There has been an increase in tropical storms and hurricanes from the previous 30-year record NOAA announced Friday. 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. 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. This combination of extreme weather can bring devastation to areas. As a result, they rarely form within 5 of the equator. Wind Shear == differences between wind speeds at different heights. This is because tropical cyclones develop over warm sea waters and follow trade winds that blow westward. All the wind that is carried upwards loses its moisture and becomes cold and dense. This effect is then tipped vertically by rising air moving up through the thunderclouds. An analysis of the frequency of cyclones on the east and west coasts of India between 1891 and 1990 shows that nearly 262 cyclones occurred on the east coast and 33 cyclones occurred on the west coast during this period. May Then, because of the rising warm humid air, a true cyclonic vortex may develop very rapidly. The cloud size decreases from center to periphery. Subsidence is distributed over a wide area on the outside of the rain band but is concentrated in the small inside area. Therefore, the polar front jet stream's location and the southern edge of the polar vortex essentially line up. The velocity of wind in a tropical cyclone is much higher and it is more damaging. Along these bands, low-level convergence is a maximum, and therefore, upper-level divergence is most pronounced above. In India, there are detection radars along both the coasts. A tornado forms when changes in wind speed and direction create a horizontal spinning effect within a storm cell. 1. Polar Vortex Impacts In the video, there is a question in which the statement Wind pattern is Clockwise in Northern Hemisphere., is incorrect as mentioned in the video. The cyclones are often characterized by existence of an anticyclone between two cyclones. Along with these bands, low-level convergence is a maximum, and therefore, upper-level divergence is most pronounced above. The United States records about 1200 tornadoes per year, whereas the Netherlands records the highest number of tornadoes per area compared to other countries. Thus. Elaborate. A well developed divergence in the upper layers of the atmosphere is necessary so that the rising air currents within the cyclone continue to be pumped out and a low pressure maintained at the center. Tropical Cyclone. (250 words) (UPSC 2014) Difficulty level: Moderate. In the northern hemisphere, the deflection is to the right (seen with the wind in the back) and in southern hemisphere, it . Convection in tropical cyclones is organized into long, narrow rain bands which are oriented in the same direction as the horizontal wind. 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. The ones at the periphery are made up of nimbostratus and cumulus clouds. Storms generally move east to west because of trade winds in the tropics, so a greater westward shift usually puts them closer to where the land is, Wang said. Tornadoes also cause damage through air pressure reductions. Tropical Cyclones Tropical cyclones are regarded as one of the most devastating natural calamities in the world. It is in a cold core (non-tropical cyclone) can also spread far away from the center of the storm. The extra tropical cyclones move from west to east but tropical cyclones, move from east to west. Cyclones occur in the pre-monsoon months of May-June and the post-monsoon months of October-November. Trade winds from both the hemispheres meet along inter-tropical front. The reason why the gusts are stronger because turbulence increases and acts to bring faster winds down to the surface in a short burst. India's geographical location marks it as a prime target for tropical cyclones originating from both the east and the west. Tropical cyclones move from east to west tracking roughly along the base of the Hadley global circulation cell. Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large scale destruction due to violent winds (squalls), very heavy rainfall (torrential rainfall) and storm surge. Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large scale destruction due to violent winds, very heavy rainfall (torrential rainfall) and storm surge. 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 falls across the band since warm air is lighter than cold air. As divergence prevails on the eastern side of the troughs, a rising motion occurs; this leads to the development of thunderstorms. Condensation occurs in this air and the cycle is repeated as long as the moisture is supplied. The remains of an upper tropospheric cyclone from the Westerlies move deep into the tropical latitude regions. The condensation of moisture releases enough. (Specific question wrt confusing options in prelims). The devastation in West Bengal in the wake of cyclone Amphan cost $13 billion in damage. 1 Year Validity == Validity of the Download links (both Static & Current Affairs) is 1 Year from the date of purchase. Hurricanes are steered by global winds. Monitoring is also done by aircraft which carry a number of instruments including a weather radar. It becomes a . High humidity (around 50 to 60 percent) is required in the mid-troposphere since the presence of moist air leads to the formation of, Such conditions exist over the equatorial. It is also the primary reason for the formation of cyclones that . These originate over oceans in tropical areas & move to coastal areas. All the wind that is carried upwards loses its moisture and becomes cold and dense. UPSC CDS 1 2023 Syllabus and Latest Exam Pattern IMA INA OTA AFA 1 hour ago; A tropical cyclone turns into a typhoon in the western Pacificnear Asiawhen it has winds of 74 MPH or greater. Subsidence is distributed over a wide area on the outside of the rain band but is concentrated in the small inside area. 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. What is the relationship between the temperature of seawater and cyclones? Clockwise in the southern hemisphere and counter clockwise in the northern hemisphere. This warm water lies well within the belt of easterly winds, so almost all the storms that form there move away from the coast, toward the west. They form near the equator over warm ocean waters. Violent cyclone or storm that originates from the oceans in a tropical area and further they move over to the coastal areas bringing about large scale destruction which is caused by violent high-speed winds, very heavy rainfall and storm surges, it is called a tropical cyclone. Large sea surface with a temperature higher than. why tropical cyclones move from east to west upsc. Torrent == a strong and fast-moving stream of water or other liquid. The wind velocity in a tropical cyclone is much higher and it is more destructive. #kt-info-box_77ac74-53 .kt-blocks-info-box-link-wrap{border-color:#ffefd9;border-radius:8px;background:var(--global-palette8, #F7FAFC);padding-top:5px;padding-right:5px;padding-bottom:5px;padding-left:5px;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;}#kt-info-box_77ac74-53 .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#ffefd9;}#kt-info-box_77ac74-53 .kadence-info-box-image-inner-intrisic-container{max-width:40px;}#kt-info-box_77ac74-53 .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_77ac74-53 .kt-info-svg-icon, #kt-info-box_77ac74-53 .kt-info-svg-icon-flip, #kt-info-box_77ac74-53 .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_77ac74-53 .kt-blocks-info-box-media{color:#444444;background:transparent;border-color:#444444;border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;padding-top:10px;padding-right:10px;padding-bottom:10px;padding-left:10px;}#kt-info-box_77ac74-53 .kt-blocks-info-box-media-container{margin-top:0px;margin-right:15px;margin-bottom:0px;margin-left:15px;}#kt-info-box_77ac74-53 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:transparent;border-color:#444444;}#kt-info-box_77ac74-53 .kt-blocks-info-box-title{color:#363636;font-size:14px;margin-top:7px;margin-right:3px;margin-bottom:12px;margin-left:3px;}#kt-info-box_77ac74-53 .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_77ac74-53 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} If you purchase the notes with Download Validity == 2 Years, on 17/01/2023, then you will be able to download the Static Files + Current Affairs files till 18/01/2025. Also called typhoons, tropical cyclones generally have been moving westward by about 18 miles per decade (30 kilometers) since 1982, putting them closer to land and making them more dangerous, a study in Thursday's journal Science said. The notes available are too much appreciable. After developing, these cyclones advance till they find a weak spot in the trade wind belt. The velocity of air is comparatively lower. 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. 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. 2. or the direction from which we are looking (equator/north pole), Is there something such as default wind pattern/direction here? This closed air circulation (whirling motion) is a result ofrapid upward movement of the hot airwhich is subjected toCoriolis force. Why are cyclones so destructive? If ocean can supply more moisture, the storm will reach a mature stage. A mature tropical cyclone west of the International Date Line (180W) and north of the Equator is a typhoon. Answer: Tropical cyclones typically form over large bodies of relatively warm water. Tropical cyclones die at 30 latitude because of cool ocean waters and increasing wind shear due to westerlies. #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;} The movement of air is. Tropical waves form in the easterly flow along the equatorial . 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. If ocean can supply more moisture, the storm will reach a mature stage. The cloud size decreases from center to periphery. Small variations in the vertical wind speed. Tropical oceans spawn approximately 80 tropical storms annually, and about two-thirds are severe (category, Copyright 2023 EarthProfessor | Powered by Astra WordPress Theme.

This is because summers and pre-monsoons see dry and hot air moving from north-western India towards the Bay. Presence of the Coriolis force enough to create a cyclonic vortex. 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. Why do temperate cyclones move from west to east? Had it been Anti-clockwise in Northern Hemisphere, it would have been correct. Also called typhoons, tropical cyclones generally have been moving westward by about 18 miles per decade (30 km) since 1982, putting them closer to land and making them more dangerous, a study in Thursday's journal Science said. These act to steer our storms and move them across the country. If the storm front is east-west, the center moves swiftly eastwards. 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. Tropical cyclones are also known as hurricanes. #kt-info-box_cf1378-a6 .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_cf1378-a6 .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_cf1378-a6 .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_cf1378-a6 .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_cf1378-a6 .kt-blocks-info-box-media .kt-info-box-image{width:30px;height:auto;}#kt-info-box_cf1378-a6 .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_cf1378-a6 .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_cf1378-a6 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_cf1378-a6 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_cf1378-a6 .kt-info-svg-icon, #kt-info-box_cf1378-a6 .kt-info-svg-icon-flip, #kt-info-box_cf1378-a6 .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_cf1378-a6 .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_cf1378-a6 .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_cf1378-a6 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_cf1378-a6 .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_cf1378-a6 .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_cf1378-a6 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} How are the tropical cyclones named across the world? In the United States, the wind above our head tends to move in a direction from west to east. .kadence-column_2962c4-77 > .kt-inside-inner-col{padding-top:1px;padding-bottom:1px;padding-left:3px;padding-right:3px;border-color:#d7d4d4;border-top-width:2px;border-right-width:2px;border-bottom-width:2px;border-left-width:2px;border-top-left-radius:10px;border-top-right-radius:10px;border-bottom-right-radius:10px;border-bottom-left-radius:10px;} The dry air flowing along the central dense overcast descends at the periphery and the eye region. Today, it is possible to detect a cyclone right from its genesis in the high seas and follow its course, giving a warning at least 48 hours prior to a cyclone strike. Tropical cyclones develop when the wind is uniform. As the air subsides, adiabatic warming takes place, and the air dries. A 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. 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. Reasons why the western coast sees fewer cyclones than . Tornadoes occur commonly in spring and the fall season and are less common in winters, Tornados have been spotted in all continents except Antarctica. Tropical cyclones across the globe, except Atlantic hurricanes, are moving closer to land in recent decades, a new study found. The source of the occurrence lies between 5-30 latitudes in both the hemisphere. They affect every single state along the eastern coast each year Odisha tops the list with 98 cyclones between 1891 and 2002. Why do Atlantic hurricanes move East to West?

Tornadoes, as well as cyclones both, occur in India. The tropical cyclones are associated with heavy rain fall and high velocity of winds for short duration at small area, sometimes the rain and associated winds are so high that it can cause damage to life and property mostly at eastern coastal areas. Because of weak vertical wind shear, cyclone formation processes are limited to latitude equatorward of the subtropical jet stream. Squall a sudden violent gust of wind or localized storm, especially one bringing rain, snow, or sleet. When a hurricane is still in the Caribbean, the tropical jet blows east to west, and the hurricane moves west to gain power. The dry air flowing along the central dense overcast descends at the periphery and the eye region. An anticyclone's winds rotate clockwise in the Northern Hemisphere around a center of high pressure. This carries the developing storms toward the east coast of the US, which means that hurricanes are prone to strike this area unless the currents veer back out to sea. Remote sensing by radars, aircraft and satellites helps predict where exactly the cyclone is going to strike. It descends to the surface through the cylindrical eye region and at the edges of the cyclone. 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. Tropical cyclones are regarded as one of the most devastating natural calamities in the world. In the thunderstorm, the air is uplifted as it is. The extra tropical cyclones move from west to east but tropical cyclones, move from east to west. A few storms recurve right next to the coast. #kt-info-box_2611e5-91 .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_2611e5-91 .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_2611e5-91 .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_2611e5-91 .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_2611e5-91 .kt-info-svg-icon, #kt-info-box_2611e5-91 .kt-info-svg-icon-flip, #kt-info-box_2611e5-91 .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_2611e5-91 .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_2611e5-91 .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_2611e5-91 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_2611e5-91 .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_2611e5-91 .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_2611e5-91 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} Origin: The origin of a tropical cyclone is thermal because it is caused by the evaporation of ocean water due to insolation in the ocean, whereas the origin of a temperate cyclone is dynamic because it occurs at the boundary of two air masses, due to the difference in temperature and pressure of the air masses. These are ferocious storms that originate over oceans in tropical areas and move over to the coastal areas causing violent winds, very heavy rainfall, and storm outpourings. Meteorologists believe the. A tropical cyclone is characterized by lack of warm/cold fronts attached, a "warm core" (air is . #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;} & amp ; move to coastal areas descends to the complete lotus arise team a typhoon UPSC 2014 Difficulty!
