These cyclones start with a westward movement, but turn northwards around 20 latitude. The remains of an upper tropospheric cyclone from the Westerlies move deep into the tropical latitude regions. One fun fact about tropical storms is that it is actually the rotation of the Earth that causes them to spin. Write about the steps that you will take. The extratropical cyclones move from west to east but tropical cyclones, move from east to west. #kt-info-box_115628-3c .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_115628-3c .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_115628-3c .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_115628-3c .kadence-info-box-image-inner-intrisic-container .kadence-info-box-image-intrisic{padding-bottom:100%;width:300px;height:0px;max-width:100%;}#kt-info-box_115628-3c .kt-info-svg-icon, #kt-info-box_115628-3c .kt-info-svg-icon-flip, #kt-info-box_115628-3c .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_115628-3c .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_115628-3c .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_115628-3c .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_115628-3c .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_115628-3c .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_115628-3c .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} #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;} Required fields are marked *, PMF IAS Environment is a One-Stop solution. Places where cold and warm fronts converge. After developing, these cyclones advance till they find a weak spot in the trade wind belt. The ones at the periphery are made up of nimbostratus and cumulus clouds. They mainly originate mainly in zones betwee n 5- 30 C Norther & South of latitude. 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. 1. the wind pattern itself (cyclone/anticyclone) Southern Pacific Ocean, Indian Ocean. Tropical cyclones are also known as hurricanes. 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. When you're outside, you might notice that one day the wind blows one direction and the next day, wind is blowing a different direction. Subsidence is distributed over a wide area on the outside of the rain band but is concentrated in the small inside area. Between 1891 and 2000, 48 tropical cyclones impacted the west coast, of which 24 were severe cyclonic storms, while about 308 cyclones, including 103 severe cyclonic storms, impacted the east coast of the country from the Bay of Bengal. It descends to the surface through the cylindrical eye region and at the edges of the cyclone. The Coriolis force explains why winds circulate around high and low pressure systems as opposed to blowing in the direction of the pressure gradient. If ocean can supply more moisture, the storm will reach a mature stage. #kt-info-box_a0fbb6-09 .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_a0fbb6-09 .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_a0fbb6-09 .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_a0fbb6-09 .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_a0fbb6-09 .kt-info-svg-icon, #kt-info-box_a0fbb6-09 .kt-info-svg-icon-flip, #kt-info-box_a0fbb6-09 .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_a0fbb6-09 .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_a0fbb6-09 .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_a0fbb6-09 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_a0fbb6-09 .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_a0fbb6-09 .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_a0fbb6-09 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} A typical mature mid-latitude cyclone or Temperate cyclones has a diameter of 1600 kilometers (1000 miles) or so. Tropical depressions are the primary reason for the monsoon rains that the Indo-Gangetic plains and most of northern India receive. Can be just almost anywhere. After developing, these cyclones advance till they find a weak spot in the trade wind belt. 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. Cyclones in the northwest Pacific that reach (exceed) 74 mph are typhoons. In the tropics, however, weather systems tend to move from east to west, because in those latitudes, the prevailing airflow is from the east. Therefore, the polar front jet stream's location and the southern edge of the polar vortex essentially line up. A As the tropical cyclone transfers energy from the ocean into the atmosphere, the ocean cools. The wind velocity in a tropical cyclone is much higher and it is more destructive. 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. Tornado formation typically needs four ingredients: Once you get a strong updraft of air being transported from the ground to the atmosphere, that column of air becomes vertical. These thunderstorms merge and create an intense low pressure system (wind is warm and lighter). Current Affairs of 2021 & earlier are available for free on PMF IAS Google Drive Folder. A category 5 cyclone, on the other hand, is extremely dangerous and has the potential for major damage. Canada reports the second largest number of tornadoes. 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. #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;} Around south-east African coast and Madagascar-Mauritius islands. I wish you do well in your life .you are a beacon of light to us in upsc preparation. How are the tropical cyclones named across the world? Andhra Pradesh has been battered by 60 cyclones in . This blocks the rise of air from the water, and the subsequent formation of clouds . A mature tropical cyclone west of the International Date Line (180W) and north of the Equator is a typhoon. It clears all the doubts arising for tropical cyclones .Thanks a ton. The velocity of wind in a tropical cyclone is much higher and it is more damaging. 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. Under normal circumstances, the red planet appears to move to the East (upwards in the gif below), but when its being overtaken by the Earth, our faster motion makes Mars appear to be going backwards (downwards in the gif below). Tropical cyclones are regarded as one of the most devastating natural calamities in the world. 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. What Is a Tropical Cyclone? In the thunderstorm, the air is uplifted as it is. Tropical cyclones move from east to west tracking roughly along the base of the Hadley global circulation cell. The Short Answer: The trade winds are winds that reliably blow east to west just north and south of the equator. #kt-layout-id_96cb19-f4{margin-top:0px;margin-bottom:0px;}#kt-layout-id_96cb19-f4 > .kt-row-column-wrap{padding-top:5px;padding-bottom:5px;padding-left:0px;padding-right:0px;} Squall a sudden violent gust of wind or localized storm, especially one bringing rain, snow, or sleet. #kt-info-box_3a0c3c-3c .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_3a0c3c-3c .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#f1f3ef;}#kt-info-box_3a0c3c-3c .kadence-info-box-image-inner-intrisic-container{max-width:30px;}#kt-info-box_3a0c3c-3c .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_3a0c3c-3c .kt-blocks-info-box-media .kt-info-box-image{width:30px;height:auto;}#kt-info-box_3a0c3c-3c .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_3a0c3c-3c .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_3a0c3c-3c .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image, #kt-info-box_3a0c3c-3c .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media .kt-info-box-image path{fill:#444444;}#kt-info-box_3a0c3c-3c .kt-info-svg-icon, #kt-info-box_3a0c3c-3c .kt-info-svg-icon-flip, #kt-info-box_3a0c3c-3c .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_3a0c3c-3c .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_3a0c3c-3c .kt-blocks-info-box-media .kadence-info-box-image-intrisic:not(.kb-info-box-image-ratio) img{border-radius:200px;}#kt-info-box_3a0c3c-3c .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:#ffffff;border-color:#eeeeee;}#kt-info-box_3a0c3c-3c .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_3a0c3c-3c .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_3a0c3c-3c .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} The devastation in West Bengal in the wake of cyclone Amphan cost $13 billion in damage. Cloud formation is dense at the center. 2. The main features of tropical cyclones are as follows. It also controls whether the air will rise or fall in temperature. As air masses are pulled into cyclones from all directions, they are deflected, and the storm systema hurricane seems to rotate counter-clockwise. Origin of Tropical Cyclones (Hurricanes) | UPSC - IAS. The 7517 km coastal area of India is hit by over 10 percent of the world's tropical cyclones year on year. Due to excess moisture over oceans, the thunderstorm intensifies and sucks in air at much faster rate. Along with these bands, low-level convergence is a maximum, and therefore, upper-level divergence is most pronounced above. - This is because summers and pre-monsoons see dry and hot air moving from north-western India towards the Bay. More Tropical cyclones occur in the Bay of Bengal than the Arabian Sea and the ratio is approximately 4:1. Winds 40-300+ mph. Tropical cyclones are violent storms that originate over oceans intropical 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. 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. These originate over oceans in tropical areas & move to coastal areas. Cyclones occur in the pre-monsoon months of May-June and the post-monsoon months of October-November. 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. The remains of an upper tropospheric cyclone from the Westerlies move deep into the tropical latitude regions. It is in a cold core (non-tropical cyclone) can also spread far away from the center of the storm. The air pressure at the tornado centre is approximately 800 millibars (average sea-level pressure is 1013 millibars) and many human-made structures collapse outward when subject to pressure drops of this magnitude. Reasons why the western coast sees fewer cyclones than . Primary References:NCERT Geography, IMD,Encyclopedia Britannica[Images],Spectrums Geography [Amazon and Flipkart] and Savindra Singh[Amazon and Flipkart]. Tropical Cyclone: It occurs over tropical ocean regions. However, unlike cyclones, the frequency of tornado outbreaks is very low. Tornadoes occur commonly in spring and the fall season and are less common in winters, Tornados have been spotted in all continents except Antarctica. They then lose energy and subside. At these locations, the strong local convectional currents acquire a whirling motion because of the Coriolis force. Love this website. A hurricane is a tropical cyclone that has maximum sustained surface winds of 74 mph or greater (64 knots or greater). Two factors explain why hurricanes very rarely form and come close to land on the west coast. 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. Why do Atlantic hurricanes move East to West? Answer (1 of 8): This is due to two factors: 1. Love this website. 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. By the time a hurricane reaches North America, it generally curves into a northerly direction, as a result of the Coriolis force (which forces a counterclockwise rotation) and steering winds at higher levels. If the storm front is directed northwards, the center moves towards the north, but after two or three days, the pressure difference declines and the cyclone dissipates. 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. Reasons for more tropical cyclones in the South China Sea, Bay of Bengal and Gulf of Mexico As areas of low pressure form, they interact with the jet stream which ultimately pushes them on through. Moving air is deflected by the rotation of the Earth. . They are irregular wind movements involving closed circulation of air around a low pressure center. The recent cyclone on the east coast of India was called "Phailin". They turn further north-eastwards around 25 latitude, and then eastwards around 30 latitude. Tornadoes, as well as cyclones both, occur in India. Some estimates suggest that around 10,000 people are killed on average each year as a result of these storms. Tropical cyclones develop when the wind is uniform. Precipitation: The extratropical cyclones have a clear frontal system which is not present in the tropical cyclones. Large sea surface with a temperature higher than. The eyes warm temperatures are due to compressional warming (adiabatic) of the subsiding air. The strong rotating winds of a tropical cyclone are a result of the conservation of angular momentum imparted by the Earth's rotation as air flows inwards toward the axis of rotation. 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. Tropical cyclones are violent storms that originate over oceans intropical areasand move over to the coastal areas bringing about large-scale destruction due to violent winds (squalls), very heavy rainfall (torrential rainfall), andstorm surge. While the sustained winds are reduced because of the dampening effect of larger roughness over land. Storms that form just west of. #kt-info-box_0b5ae0-04 .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_0b5ae0-04 .kt-blocks-info-box-link-wrap:hover{border-color:#eeeeee;background:#ffefd9;}#kt-info-box_0b5ae0-04 .kadence-info-box-image-inner-intrisic-container{max-width:40px;}#kt-info-box_0b5ae0-04 .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_0b5ae0-04 .kt-info-svg-icon, #kt-info-box_0b5ae0-04 .kt-info-svg-icon-flip, #kt-info-box_0b5ae0-04 .kt-blocks-info-box-number{font-size:50px;}#kt-info-box_0b5ae0-04 .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_0b5ae0-04 .kt-blocks-info-box-media-container{margin-top:0px;margin-right:15px;margin-bottom:0px;margin-left:15px;}#kt-info-box_0b5ae0-04 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-media{color:#444444;background:transparent;border-color:#444444;}#kt-info-box_0b5ae0-04 .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_0b5ae0-04 .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_0b5ae0-04 .kt-blocks-info-box-link-wrap:hover .kt-blocks-info-box-learnmore{color:#ffffff;background:#444444;border-color:#444444;} It descends to the surface through the cylindrical eye region and at the edges of the Date.
