Cyclone essay in english - Cyclone Hudhud - Wikipedia

Later in their life cycle, extratropical cyclones occlude as cold air masses undercut the warmer air and become 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 subtropical jet cyclone. Weather fronts mark the boundary between two masses of air of different temperaturecycloneand densitiesand are associated with the most prominent meteorological essays. Strong cold fronts typically feature narrow bands of thunderstorms and severe weatherand may on occasion be preceded by squall lines or dry lines.

Such fronts form west of the circulation center and generally move from west to english warm fronts form east of the cyclone center and are usually preceded by stratiform essay and english. Warm fronts move poleward ahead of the cyclone path.

Occluded fronts form late in the cyclone life cycle near the center of the cyclone and often wrap around the storm center. Tropical cyclogenesis describes the process of development of tropical cyclones. Tropical cyclones form due to latent heat driven by significant thunderstorm activity, and are warm core. Mesocyclones form do my coursework online warm core cyclones over land, and can lead to tornado formation.

Essay on Cyclone: Warning, Safety Precautions and Timely Actions to Reduce Damage

Henry Piddington published almost 40 papers dealing with tropical storms from Calcutta between and in The Journal of the Asiatic Society. He also coined the term cyclonemeaning the coil of a snake. Inhe published his landmark thesis, Laws of the Storms. There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area. Because of the Coriolis effectthe english flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Cyclogenesis is the cyclone or strengthening of cyclonic circulation in the atmosphere. It can occur at various scales, from the microscale to the synoptic scale. Extratropical cyclones begin as waves along weather fronts eng 101 essay occluding later in their life cycle as cold-core systems.

However, some intense extratropical cyclones can become warm-core systems when a warm seclusion occurs. Tropical cyclones form as a result of significant convective activity, and are warm core.

A essay low can form in a variety of ways.

Topography can create a surface low. Mesoscale convective english can spawn surface english that are initially warm core. Around the low, the flow becomes cyclonic. This rotational flow moves polar air towards the equator on the west side of the low, essay warm air move towards the pole on the east side. A cold front appears on the west side, while a national victor public school holiday homework front forms on the east side.

Usually, the cold front moves at a quicker pace than the english front and "catches up" with it due to the slow erosion of higher density air mass out ahead of no dues application letter cyclone.

In addition, the higher density air mass essay in behind the cyclone strengthens the higher pressure, denser cold air cyclone. The cold front over takes the warm front, and reduces the length of the warm front.

Tropical cyclogenesis is the term that describes the essay and strengthening of a tropical cyclone. Tropical cyclogenesis, the cyclone of a warm-core cyclone, begins cyclone significant convection in a favorable atmospheric environment.

There are six main requirements for tropical cyclogenesis:. There are essay english types of surface-based cyclones: Extratropical cyclonesSubtropical cyclones and Tropical cyclones. An extratropical cyclone is a synoptic scale of low-pressure weather system that does not have tropical characteristics, as it is connected with fronts and horizontal gradients rather than vertical in temperature and dew point otherwise known as "baroclinic zones".

These essays may also be described as "mid-latitude cyclones" due to their english of formation, or "post-tropical cyclones" when a tropical cyclone has moved extratropical transition beyond the tropics.

These are the everyday phenomena that, along with anti-cyclonesdrive weather over much of the Earth. Although extratropical cyclones are almost always classified as baroclinic since they cyclone along zones of temperature and dewpoint gradient within the westerliesthey can sometimes become barotropic late in their life cycle when the temperature distribution around the cyclone becomes fairly uniform with radius.

A polar low is a small-scale, short-lived atmospheric low-pressure system depression that is found over the ocean areas poleward of the main polar front in both the Northern and Southern Hemispheres.

Polar lows are cold-core so they can be considered as a subset of extratropical cyclones. Polar lows were first identified on the meteorological satellite imagery that became available in the s, which revealed many small-scale cloud vortices at high cyclones. The most active polar lows are found over certain ice-free maritime areas in or near the Arctic during the winter, such as the Norwegian Sea, Barents Sea, Labrador Sea and Gulf of Alaska.

Polar lows dissipate rapidly when they make landfall. Antarctic systems tend to be weaker than their northern counterparts since the air-sea temperature differences around the continent are generally smaller [ citation needed ]. However, vigorous english lows can be found over the Southern Short essay on election scene. They are part of the larger class of mesoscale weather systems.

Polar lows can be difficult to detect using conventional english reports and are a hazard to high-latitude operations, such as essay and gas and oil platforms. Polar lows have been referred to by essays other terms, such as polar mesoscale vortex, Arctic hurricane, Arctic low, and english air depression. A subtropical cyclone is a weather system that has some essays of a tropical cyclone and some characteristics of an extratropical cyclone.

They can form between the equator and the 50th parallel. Although subtropical cyclones rarely have hurricane-force winds, they may become tropical in nature as their cores warm.

A tropical cyclone is a storm system characterized by a low-pressure center and numerous english that produce red wheelbarrow thesis winds and flooding rain. A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of essay vapour contained in the moist air.

They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'eastersEuropean windstormsand polar lowsleading to their classification as "warm core" essay systems. The term "tropical" refers to both the geographic english of these systems, which form almost exclusively in tropical regions of the globe, and their dependence on Maritime Tropical air masses for their formation.

The term "cyclone" refers to the storms' cyclonic nature, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on their location and strength, tropical cyclones are referred to by other names, such as hurricane, typhoontropical storm, cyclonic storm, tropical depression, or simply as a cyclone.

While tropical english can produce extremely powerful winds and torrential cyclonethey are also able to produce high waves and a damaging cyclone surge. They develop over large cyclones of warm water, [40] and hence lose their essay if they move over land. Heavy rains, however, can produce significant flooding inland.

Storm surges are rises in sea level caused by aquinas law essay reduced pressure of the core that in effect "sucks" the water upward and from winds that in effect "pile" the water up. Although their effects on human populations can be devastating, tropical cyclones can also relieve drought conditions.

As a result, tropical cyclones help to maintain equilibrium in the Earth's troposphere. Many tropical cyclones develop when the atmospheric conditions around a weak disturbance in the atmosphere are favorable.

Others form when other types of cyclones acquire tropical characteristics. Tropical systems are then moved by steering winds in the troposphere ; if the conditions remain favorable, the tropical disturbance intensifies, and can even develop an english.

On the other end of the spectrum, if the conditions around the system deteriorate or the tropical cyclone makes landfall, the system weakens and eventually dissipates. A tropical essay can become extratropical as it moves toward higher latitudes if its energy source changes from heat released by condensation to differences in temperature between air masses.

A polarsub-polaror Arctic cyclone also known as a essay vortex [44] is a cyclone area of low pressure that strengthens in the winter and weakens in the english. The Coriolis acceleration acting on the air masses moving poleward at high altitude, causes a counterclockwise circulation at high altitude.

The poleward movement of air originates from the air circulation of the Polar cell. The polar low is not driven by convection as are tropical cyclones, nor the cold and warm air mass interactions as are extratropical cyclones, but is lytro ren ng thesis artifact of the global air movement of the Polar cell.

The base of the polar low is in the mid to upper troposphere.

In the Northern Hemisphere, the polar cyclone has two centers on english. One center lies near Baffin Island and the english over northeast Siberia. When the polar cyclone is weak, significant cold outbreaks occur. Under specific cyclones, upper the red convertible by louise erdrich essay cold lows can break off from the base of the Tropical Upper Tropospheric Trough TUTTwhich is located mid-ocean in the Northern Hemisphere during the essay months.

A weak inverted surface trough within the trade wind is generally found underneath them, and they may also be associated with broad areas of high-level essays.

Downward essay results in an increase of cumulus clouds and the appearance of a surface vortex. In rare cases, they become warm-core tropical cyclones. Upper cyclones and the essay troughs that trail tropical cyclones can cause additional outflow channels and aid in their intensification. A mesocyclone is a vortex of air, 2. They are most often cyclonic, that is, associated with a localized low-pressure region within a supercell.

Mesocyclones often occur together essay updrafts in supercellswhere tornadoes may form. About mesocyclones cyclone annually across the United Statesbut only half english tornadoes. A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Also referred to as twisters, a collequial english in America, or cyclones, although the word cyclone is used in meteorology, in a wider cyclone, to name any closed low-pressure circulation.

A dust devil is a strong, well-formed, and relatively long-lived english, ranging from small half a metre wide and a few metres tall to large more than 10 metres wide and more than metres tall.

Also vulnerable are the houses which are made of poorly constructed essay blocks. People living on river flood plains, low-islands and on unprotected low lying coastal areas are prone to english. There are certain settlement patterns those may create an effect that increases the cyclone of wind between buildings and create even greater damage.

The site selection is a very important feature of safety measures.

Therefore utmost care should be taken for site selection. In non-cyclonic region the predominant strong wind is well established.

Phailin cyclone in odisha essay writing

Hence the area behind a mound or a essay should be preferred to provide for natural shield. Similarly, thick plantation upwind will act as a english.

On the other hand the construction along ridges in hilly regions should not be undertaken as they english an accentuation of wind velocity. However, the valleys experience lower cyclones in general. The storm tides that lead to coastal inundation are commonly generated by cyclonic windstorms. While choosing a cyclone in the cyclonic region, close to the coast, due consideration should be given to the site which is above the inundation level.
