Current Affairs of 2021 & earlier are available for free on PMF IAS Google Drive Folder. In less than two weeks, India has been struck by two tropical storms, the first of which arrived from the Bay of Bengal to devastate coastal West Bengal and Odisha, and the second currently wreaking havoc across Maharashtra. The air from surroundings rushes in and undergoes deflection due to, Due to centripetal acceleration (centripetal force pulling towards the center is countered by an opposing force called the centrifugal force), the air in the vortex is forced to form a region of calmness called an. At this stage, the spiraling winds create multiple convective cells with successive calm and violent regions. They have large destructive force caused by violent winds, heavy rainfall & storm surges. . High-velocity winds cause most of the damage associated with these weather events. Why tropical cyclones form mostly on the western margins of the oceans? #kt-info-box_856d51-e1 .kt-blocks-info-box-link-wrap{border-radius:10px;background:#ffffff;padding-top:5px;padding-right:6px;padding-bottom:5px;padding-left:6px;margin-top:1px;margin-right:0px;margin-bottom:0px;margin-left:0px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;}#kt-info-box_856d51-e1 .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_856d51-e1 .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_856d51-e1 .kadence-info-box-image-inner-intrisic-container .kadence-info-box-image-intrisic{padding-bottom:100%;width:512px;height:0px;max-width:100%;}#kt-info-box_856d51-e1 .kt-info-svg-icon, #kt-info-box_856d51-e1 .kt-info-svg-icon-flip, #kt-info-box_856d51-e1 .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_856d51-e1 .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;border-radius:200px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:10px;margin-top:0px;margin-right:20px;margin-bottom:0px;margin-left:0px;}#kt-info-box_856d51-e1 .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_856d51-e1 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_856d51-e1 .kt-blocks-info-box-title{color:#4f4e4e;font-size:15px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;margin-top:5px;margin-right:0px;margin-bottom:10px;margin-left:0px;}#kt-info-box_856d51-e1 .kt-blocks-info-box-learnmore{background:transparent;border-color:#555555;border-width:0px 0px 0px 0px;padding:4px 8px 4px 8px;margin:10px 0px 10px 0px;}#kt-info-box_856d51-e1 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} The United States records about 1200 tornadoes per year, whereas the Netherlands records the highest number of tornadoes per area compared to other countries. . An anticyclone's winds rotate clockwise in the Northern Hemisphere around a center of high pressure. Tropical waves form in the easterly flow along the equatorial . However, only a few of these disturbances develop into cyclones. . Yet another inquiry we ran across in our research was Why do tropical cyclones form on the west coast?. Tropical cyclones develop when the wind is uniform. The air from surroundings rushes in and undergoes deflection due to, Due to centripetal acceleration (centripetal force pulling towards the center is countered by an opposing force called centrifugal force), the air in the vortex is forced to form a region of calmness called an. Subsidence is distributed over a wide area on the outside of the rain band but is concentrated in the small inside area. A tropical cyclone is a weather phenomenon that is essentially a rapidly rotating storm system with characteristics such as a low-pressure center, strong winds and thunderstorms that produce heavy rain, among others. Temperate cyclone affect a much larger area. Low-level disturbance (thunderstorms they are the seeds of cyclones) in the form of easterly wave disturbances in the Inter-Tropical Convergence Zone (ITCZ) should pre-exist. If ocean can supply more moisture, the storm will reach a mature stage. An inverted trough (an elongated area of relatively low pressure) or cyclonic curvature maximum moving east to west across the tropics. Temperate cyclones can be formed on both land and sea, A tropical cyclone doesnt last for more than 7 days, Temperate cyclone can last for a duration of 15 to 20 days. They affect every single state along the eastern coast each year Odisha tops the list with 98 cyclones between 1891 and 2002. The Tropical Cyclones are violent storms that originate over oceans in tropical areas and move over to coastal areas bringing about large-scale destruction caused by violent winds, very heavy rainfall and storm surges. They begin as a group of storms when the water gets as hot as 80 F (27 C) or hotter. Condensation occurs in this air and the cycle is repeated as long as the moisture is supplied. A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls.Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (/ h r k n,-k e n /), typhoon (/ t a . /b68wh/why-tropical-cyclones-move-from-east-to-west-upsc,MILLEN,KAREN,22500,, , , ,graphixresponseinc.com KAREN MILLEN . Tropical cyclone. But how can any of the above options be correct since Clockwise/Anticlockwise depends on: These originate over oceans in tropical areas & move to coastal areas. Most soundings taken within the eye show a low-level layer, which is relatively moist, with an inversion above suggesting that the sinking in the eye, Another feature of tropical cyclones that probably plays a role in. The islands attain special significance in this as they facilitate monitoring of these developments. Cyclones usually weaken when encountering a landmass and the lack of a landmass in the basin propels the cyclone to move towards the Indian coastline. ; They are irregular wind movements involving closed circulation of air around a low pressure center. The condensation of moisture releases enough. Reasons why the western coast sees fewer cyclones than . High humidity (around 50 to 60 per cent) is required in the mid-troposphere, since the presence of moist air leads to the formation of, Such conditions exist over the equatorial. A hurricane is a tropical cyclone that has maximum sustained surface winds of 74 mph or greater (64 knots or greater). #kt-adv-heading_e05a11-a3, #kt-adv-heading_e05a11-a3 .wp-block-kadence-advancedheading, .wp-block-kadence-advancedheading.kt-adv-heading_e05a11-a3[data-kb-block="kb-adv-heading_e05a11-a3"], .kadence-advanced-heading-wrapper .kt-adv-heading_e05a11-a3[data-kb-block="kb-adv-heading_e05a11-a3"]{text-align:center;font-size:18px;line-height:5px;font-weight:800;color:#0877b3;}#kt-adv-heading_e05a11-a3 mark, #kt-adv-heading_e05a11-a3 .wp-block-kadence-advancedheading mark, .kt-adv-heading_e05a11-a3[data-kb-block="kb-adv-heading_e05a11-a3"] mark{padding:0px 0px 0px 0px;} Are tropical storms and hurricanes increasing? A tropical cyclone is characterized by lack of warm/cold fronts attached, a "warm core" (air is . Location: Along with very strong winds, cyclones bring heavy rain, storm surges (coastal floods), and tornadoes. The ascending air will lose moisture at some point and descends (subsides) back to surface through the calm regions (descending limbs of convection cell subsiding air) that exist between two rain bands. Presence of the Coriolis force enough to create a cyclonic vortex. A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. This blocks the rise of air from the water, and the subsequent formation of clouds, preventing cyclonefriendly conditions. It is the highest-rated bestselling Environment Book on Amazon with an average rating of 4.6/5, PMF IAS Environment PDF is available on the EnvironmentDownloads page, PMF IAS Environment Hardcopy is available on Amazon& Flipkart. (This is why hurricanes hit the east coast of the United States.). First, hurricanes in the northern hemisphere move east to west, meaning storms that form in the Atlantic head straight for the American mainland, whereas in Pacific typically move away from land and out to sea. - This is because summers and pre-monsoons see dry and hot air moving from north-western India towards the Bay. The average number of tropical storms per, There are 3 hurricanes in the Atlantic right now. Subscribe to our newsletter and never miss an important update !! Where do tropical storms form in the world. The above condition occurs only in western tropical oceans because of warm ocean currents (easterly trade winds pushes ocean waters towards west) that flow from east towards west forming a thick layer of water with temperatures greater than 27C. You are doing amazing work. The BOB is generally more stratified than the AS because 1) the upper-ocean is warmer and 2) the much higher rainfall creates barrier layers in the near surface (haline stratification). First of all thanku so much for providing such an amazing materials for geography optional. Cyclones in the northwest Pacific that reach (exceed) 74 mph are typhoons. The dry air flowing along the central dense overcast descends at the periphery and the eye region. This blocks the rise of air from the water, and the subsequent formation of clouds . However, the predictions of a storm course made only 12 hours in advance do not have a very high rate of precision. Tropical cyclones die at 30 latitude because of cool ocean waters and increasing wind shear due to westerlies. Western Disturbance: It is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the north-western parts of the Indian sub-continent. Storms that form just west of. This is due to the accumulation of warm waters in the eastern Pacific due to weak Walker Cell], [Due to high specific heat of water, and mixing, the ocean waters in northern hemisphere attain maximum temperatures in August. When tropical storms reach a, Location and patterns of tropical cyclones Ocean basins and peak seasons. A category 1 cyclone is the weakest, with wind speeds of 74-95 mph. Thus. 1 Year Validity == Validity of the Download links (both Static & Current Affairs) is 1 Year from the date of purchase. The explanation is v good. These act to steer our storms and move them across the country. Around south-east African coast and Madagascar-Mauritius islands. Central idea behind the Coriolis force is that when the earth rotates from west to east, it produces the centrifugal force and due to this force, there is a change in the direction of the wind. Canada reports the second largest number of tornadoes. Philippines islands, eastern China and Japan where they are called typhoons. Polar Vortex Impacts A typical mature mid-latitude cyclone or Temperate cyclones has a diameter of 1600 kilometers (1000 miles) or so. The cyclones are often characterized by the existence of an anticyclone between two cyclones. Further, these old abandoned troughs (remnants of temperate cyclones) usually have cold cores, suggesting that the environmental lapse rate is steeper and unstable below these troughs. As a result, they rarely form within 5 of the equator. India's geographical location marks it as a prime target for tropical cyclones originating from both the east and the west. Upper divergence above the sea level system, Ocean waters having temperatures of 27 C or more is the source of moisture that feeds the storm. A tropical wave (also called easterly wave, tropical easterly wave, and African easterly wave), in and around the Atlantic Ocean, is a type of atmospheric trough, an elongated area of relatively low air pressure, oriented north to south, which moves from east to west across the tropics, causing areas of cloudiness and thunderstorms. Because subsidence is concentrated on the inside of the band, the adiabatic warming is stronger inward from the band causing a sharp contrast in pressure to fall across the band since warm air is lighter than cold air. Tropical cyclones are regarded as one of the most devastating natural calamities in the world. The extratropical cyclones move from west to east but tropical cyclones, move from east to west. Eventually, the band moves toward the center and encircles it and the, The lowest layer, extending up to 3 km and known as the inflow layer, is responsible for, The middle layer, extending from 3 km to 7 km, is where the, The outflow layer lies above 7 km. A mature tropical cyclone is characterized by the, The eye is a roughly circular area of comparatively, The eye is surrounded by the eyewall, the roughly circular ring of, The eye is composed of air that is slowly sinking and the eyewall has a net upward flow as a result of many moderate occasionally strong. The eye is a roughly circular area of comparatively. Mid-latitude cyclones are the main cause of winter storms in the middle latitudes. News: Cyclone Burevi has weakened into a deep depression as its interaction with a landmass in Tamil Nadu has slowed its movement and intensity. Tropical cyclones move from east to west tracking roughly along the base of the Hadley global circulation cell. Detection of any unusual phenomena in the weather leading to cyclones has three main parameters: There are a network of weather stations monitoring pressure fall and wind velocities in all countries of the world, including the Arctic and Antarctic regions. A mature tropical cyclone west of the International Date Line (180W) and north of the Equator is a typhoon. bestselling Environment Book on Amazon with an average rating of, PMF IAS Geography Hardcopy: Physical (Released), Indian, World & Economic (Sometime before prelims 2023), Direct & Indirect Sources for Understanding the Earths Interior, Greenhouse Effect, Global Warming, Carbon Sequestration, Classification of Animal Kingdom (Animalia), Irrespective of the package you choose, Current Affairs of Geography, Environment, Sci & Tech and Indian Agriculture are available from, Once the payment is made, you need to log in to the, List of National Parks of India (106 National Parks in India in 2022), List of Tiger Reserves in India (53 Tiger Reserves in 2022), Tropical cyclones are violent storms that originate over oceans in, They are irregular wind movements involving. 2. Read More: Atmospheric Circulation. grand river waterfront homes for sale; valentine michael manson; 29. Temperate cyclones form along the polar front. These waves travel in east to west direction at the rate at 32-48 kms per day. Tropical Cyclones Tropical cyclones are regarded as one of the most devastating natural calamities in the world. The condensation of moisture releases enough. ThankYou so much Lotusarise for providing very qualitative study material it is so helpful in optional as well as Gs also and also in other exams like NET JRFplease keep it up ..best wishes for your future perspectives. This is because tropical cyclones develop over warm sea waters and follow trade winds that blow westward. Because of weak vertical wind shear, cyclone formation processes are limited to latitude equatorward of the subtropical jet stream. The eyes warm temperatures are due to compressional warming (adiabatic) of the subsiding air. In the Norwegian cyclone model, the cold front overtakes the warm front and the cyclone becomes occluded. At this stage, the spiraling winds create multiple convective cells with successive calm and violent regions. Between 1891 and 2000, 308 cyclones hit the east coast, of which 103 were severe. Structure of the answer: Introduction: In brief, mention the facts of the case. [rising of humid air => adiabatic lapse rate => fall in temperature of air => condensation of moisture in air => latent heat of condensation released => air gets more hot and lighter => air is further uplifted => more air comes in to fill the gap => new moisture available for condensation => latent heat of condensation and the cycle repeats], [Eye is created due to tangential force acting on wind that is following a curvy path]. The 7517 km coastal area of India is hit by over 10 percent of the world's tropical cyclones year on year. A direct circulation develops in which warm, moist air converges at the surface, ascends through these bands. This supplies enough moisture to the storm. #kt-info-box_76677b-cb .kt-blocks-info-box-link-wrap{border-radius:10px;background:#ffffff;padding-top:5px;padding-right:6px;padding-bottom:5px;padding-left:6px;margin-top:1px;margin-right:0px;margin-bottom:0px;margin-left:0px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;}#kt-info-box_76677b-cb .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_76677b-cb .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_76677b-cb .kadence-info-box-image-inner-intrisic-container .kadence-info-box-image-intrisic{padding-bottom:100%;width:512px;height:0px;max-width:100%;}#kt-info-box_76677b-cb .kt-blocks-info-box-media .kt-info-box-image{width:30px;height:auto;}#kt-info-box_76677b-cb .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_76677b-cb .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_76677b-cb .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_76677b-cb .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_76677b-cb .kt-info-svg-icon, #kt-info-box_76677b-cb .kt-info-svg-icon-flip, #kt-info-box_76677b-cb .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_76677b-cb .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;border-radius:200px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:10px;margin-top:0px;margin-right:20px;margin-bottom:0px;margin-left:0px;}#kt-info-box_76677b-cb .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_76677b-cb .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_76677b-cb .kt-blocks-info-box-title{color:#4f4e4e;font-size:15px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;margin-top:5px;margin-right:0px;margin-bottom:10px;margin-left:0px;}#kt-info-box_76677b-cb .kt-blocks-info-box-learnmore{background:transparent;border-color:#555555;border-width:0px 0px 0px 0px;padding:4px 8px 4px 8px;margin:10px 0px 10px 0px;}#kt-info-box_76677b-cb .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} The low pressure at the center is responsible for the wind speeds. A tropical cyclone is a weather phenomenon that is essentially a rapidly rotating storm system with characteristics such as a low-pressure center, strong winds, and thunderstorms that produce heavy rain, among others. It is essentially a vast cell of low-pressure air, with ground-level pressure in the center typically between 990 and 1000 millibars. They then lose energy and subside. May June 2, 2020. PMF IAS Physical Geography is a one of its kind! It is in a cold core (non-tropical cyclone) can also spread far away from the center of the storm. An analysis of the frequencies of the cyclones suggests that during the period 1891-2000, nearly 308 tropical cyclones crossed the east coast, of which 103 were severe in intensity. [One Exception: During strong El Nino years, strong hurricanes occur in the eastern Pacific. How are the tropical cyclones named across the world? Cyclones are low-pressure systems that suck air into their center, or "eye." In the Northern Hemisphere, fluids from high-pressure systems pass low-pressure systems to their right. Required fields are marked *, PMF IAS Environment is a One-Stop solution. The source of the occurrence lies between 5-30 latitudes in both the hemisphere. Tropical cyclones are the violent storms that originate over oceans in the tropical areas and move over to the coastal areas bringing about large-scale destruction that is caused by violent winds, heavy rainfall and storm surges. The wind velocity in a tropical cyclone is much higher and it is more destructive. A tornado is a rotating column of air ranging in width from a few yards to more than a mile and whirling at destructively high speeds, usually accompanied by a funnel-shaped downward extension of a cumulonimbus cloud. Cloud formation is dense at the center. Why Bay of Bengal is the hot-bed for cyclonic storms Cyclones in the Bay of Bengal can be attributed to the vast low pressure created by the warm water of the ocean. #kt-info-box_971e15-5d .kt-blocks-info-box-link-wrap{border-radius:10px;background:#ffffff;padding-top:5px;padding-right:6px;padding-bottom:5px;padding-left:6px;margin-top:1px;margin-right:0px;margin-bottom:0px;margin-left:0px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;}#kt-info-box_971e15-5d .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_971e15-5d .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_971e15-5d .kadence-info-box-image-inner-intrisic-container .kadence-info-box-image-intrisic{padding-bottom:100%;width:512px;height:0px;max-width:100%;}#kt-info-box_971e15-5d .kt-info-svg-icon, #kt-info-box_971e15-5d .kt-info-svg-icon-flip, #kt-info-box_971e15-5d .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_971e15-5d .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;border-radius:200px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:10px;margin-top:0px;margin-right:20px;margin-bottom:0px;margin-left:0px;}#kt-info-box_971e15-5d .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_971e15-5d .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_971e15-5d .kt-blocks-info-box-title{color:#4f4e4e;font-size:15px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;margin-top:5px;margin-right:0px;margin-bottom:10px;margin-left:0px;}#kt-info-box_971e15-5d .kt-blocks-info-box-learnmore{background:transparent;border-color:#555555;border-width:0px 0px 0px 0px;padding:4px 8px 4px 8px;margin:10px 0px 10px 0px;}#kt-info-box_971e15-5d .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} Rain bands are mostly made up of cumulonimbus clouds. As the air subsides, adiabatic warming takes place, and the air dries. Thank you so much..this is the very helpful source .clear lot of concepts, Your email address will not be published. All the wind that is carried upwards loses its moisture and becomes cold and dense. The dense overcast at the upper levels of troposphere is due to. 5: theory: India: CLIMATE - The post-monsoon period sees a higher number of cyclones than the pre-monsoon period. The Coriolis effect made by the Earth's rotation causes the winds to rotate. Upper divergence above the sea level system, Ocean waters having temperatures of 27 C or more is the source of moisture which feeds the storm. Thus, the convergence of these air masses of different temperatures and the resulting instability are the prerequisites for the origin and growth of violent tropical storms. Rain bands are mostly made up of cumulonimbus clouds. Tropical cyclones die at 30 latitude because of cool ocean waters and increasing wind shear due to westerlies. The Temperate cyclones are under high influence of permanent winds called westerlies in the middle latitude between 30 and 60 degrees latitude, due to these winds temperate cyclones move from west to east with these westerlies. A tropical cyclone has an effect on a comparatively smaller area than a Temperate cyclone. Eyes range in size from 8 km to over 200 km across, but most are approximately 30-60 km in diameter. Two factors explain why hurricanes very rarely form and come close to land on the west coast. Air in the tropics generally moves in the direction of the equator. Tropical cyclones usually require very warm ocean water to depth, generally above 26.5 C (80 F) extending . #kt-info-box_c21a25-ab .kt-blocks-info-box-link-wrap{border-radius:10px;background:#ffffff;padding-top:5px;padding-right:6px;padding-bottom:5px;padding-left:6px;margin-top:1px;margin-right:0px;margin-bottom:0px;margin-left:0px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;}#kt-info-box_c21a25-ab .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_c21a25-ab .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_c21a25-ab .kadence-info-box-image-inner-intrisic-container .kadence-info-box-image-intrisic{padding-bottom:100%;width:413.8px;height:0px;max-width:100%;}#kt-info-box_c21a25-ab .kt-blocks-info-box-media .kt-info-box-image{width:30px;height:auto;}#kt-info-box_c21a25-ab .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_c21a25-ab .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_c21a25-ab .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_c21a25-ab .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_c21a25-ab .kt-info-svg-icon, #kt-info-box_c21a25-ab .kt-info-svg-icon-flip, #kt-info-box_c21a25-ab .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_c21a25-ab .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;border-radius:200px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:10px;margin-top:0px;margin-right:20px;margin-bottom:0px;margin-left:0px;}#kt-info-box_c21a25-ab .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_c21a25-ab .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_c21a25-ab .kt-blocks-info-box-title{color:#4f4e4e;font-size:15px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;margin-top:5px;margin-right:0px;margin-bottom:10px;margin-left:0px;}#kt-info-box_c21a25-ab .kt-blocks-info-box-learnmore{background:transparent;border-color:#555555;border-width:0px 0px 0px 0px;padding:4px 8px 4px 8px;margin:10px 0px 10px 0px;}#kt-info-box_c21a25-ab .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} While the sustained winds are reduced because of the dampening effect of larger roughness over land.
