Intro to cylones:
In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth.[1][2] This is usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure.[3][4] The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. According to the NHC glossary, warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale.[5] Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale.[6] Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the Tropical Upper Tropospheric Trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars and Neptune.[7][8] Cyclogenesis describes the process of cyclone formation and intensification.[9] Extratropical cyclones form as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract to form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, cyclones occlude as cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the cancer or subtropical jet stream.
Phailin into: The 'very severe' cyclonic storm will make a landfall on Odisha and Andhra on Saturday. The Odisha government has issued a high alert.
Here's all that you need to know about the tropical cyclone Phailin: # It is classified as a Severe Cyclonic Storm. The India Meteorological Department's (IMD), latest bulletin says it originated over east central Bay of Bengal and has now intensified as it moved Northwestwards 800km southeast of Paradip, and 870

    Hurricanes can form very quickly and destroy communities in only a few days. Hurricanes are caused by warm, moist air being present over the ocean. The air rises up near the surface. The warm air rises so there is low pressure below. Air from nearby areas with higher pressure moves to areas with lower pressure. That air turns warm and moist and then rises. The surrounding air takes the place of that air. As the warm air cools, water in the air turns into clouds. The clouds and winds spin and grow, collecting the oceans heat and water from the surface (Erickson and Leon, 2017, p. 1-5). While the storm continues to grow it will reach different stages. At 38 miles per hour it is considered a tropical depression. Tropical depressions then become tropical storms and are given a name. Every six years a list of names is reused. These…

    Hurricane Katrina began as a very low pressure weather system, which strengthened to become a tropical storm and eventually a hurricane as it moved west and neared the Florida coast on the evening of 25 August. After crossing southern Florida - where it left some 100,000 homes without power - it strengthened further before veering inland towards Louisiana, eventually making landfall at Grand Isle, approximately 90km south of New Orleans.…

    A tropical cyclone is a storm system in the Southern Hemisphere, with a closed circulation around a center of low pressure, driven by heat energy released as moist air drawn in over warm ocean waters rises and condenses. The circular eye or centre of a tropical cyclone is an area characterised by light winds and often by clear skies. They derive their energy from the warm tropical oceans and do not form unless the sea-surface temperature is above 26.5°C, although, once formed, they can persist over lower sea-surface temperatures. Depending on their location and strength a cyclone be named otherwise like tropical storm, tropical depression, hurricane or typhoon. They can carry extremely high winds, tornadoes, torrential rain, and storm surge onto coasts, leading to mudslides, flash floods, and lightning sparked fires in addition to wind damage.…

    A tropical revolving storm is a term that covers hurricanes, tropical cyclones, typhoons and willy-willies. These intense low-pressure weather systems are associated with catastrophic wind speeds averaging at 120kmph and torrential rainfall. Tropical revolving storms are huge and extremely violent extending to about 500km in diameter. They occur in the tropics and the sub-tropics and form over the oceans where sea surface temperatures are above 27’C.…

    Low pressure atmospheric systems are also known as depressions or cyclones and they form in mid- and high-latitudes. They are formed by the mixing of cold and warm air, the warm air is lighter, so it rises above the denser, cold air and forms a centre of low pressure. High pressure atmospheric systems are also known as anticyclones and have very different characteristics to depressions. Anticyclones are large masses of subsiding air, which produces high pressure at the surface. There are a variety of difference between anticyclones and depressions, including the weather conditions, the length of time they last and the impact they have upon diverse countries and areas.…

    Most hurricanes appear in late summer or early fall, when sea temperatures are at their highest. The warm waters heat the air above it, and the updrafts of warm, moist air begin to rise. At that longitude in the tropics, there is usually a layer of warm, dry air that acts like an invisible ceiling or lid. Once in a while, the lid that prevents the hurricane from forming is destroyed. Scientists do not know why this happens; however, when it does, it's the first step in the birth of a hurricane. With the lid off, the warm, moist air rises higher and higher. Heat energy, released as the water vapor in the air, condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli clouds become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapor. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts raise faster, pulling in even larger amounts of air and water vapor from the storm's edges. And as the updrafts speed up, air swirls faster and…

    Cyclones experience air that converges and rises, creating low pressure at the surface. Northern hemisphere cyclonic circulations are mirrored in the southern hemisphere. For instance, in the northern hemisphere winds move counterclockwise and in the southern hemisphere winds move clockwise following the geostrophic pattern resemblance to isobars. In the northern hemisphere the wind flow pattern joins cool air that is from the north with warm air that is from the south. Then two fronts are created. A cold front extends to the southwest from the center along the pressure trough and a warm front extends eastward from the center consecutively along a, typically weaker, pressure trough. Different sectors are then created. A cool sector is along northern and western sides of the center and a warm sector is along the southern and eastern sides. The majority of the cool sector is at the surface and the warm sector is more widespread aloft as the cold air pushes up the warm…

    A hurricane is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 74 mph. It forms and intensifies over tropical oceanic regions. Hurricanes are generally smaller than storms in mid-latitudes, typically about 311 miles in diameter. At the ocean’s surface, the air spirals inward in a counterclockwise direction. This cyclonic circulation becomes weaker with height, eventually turning into clockwise outflow near the top of the storm.…

    The earth has been affected by the natural hazards over a long time as man emerged into the picture that the natural occurrences were becoming disaster, together with being documented in various ways providing a warning for the future generation. Nature is our wise old teacher, if we are willing to observe, listen and learn both in happier times and in our responses to the powerful forces of nature that have the capacity to destroy us, there are lessons to be learnt. Two strong lessons emerge from India’s response to cyclone Phailin — when there is a will to do something, India has the competence, capability and resources.…
