Tropical Cyclones and Their Distribution
Tropical Cyclones and Their Distribution. Tropical Cyclones are Low Pressure system in which turbulent wind blows. tropical cyclones typhoons , hurricanes and tornadoes are different names of tropical cyclones according to different regions. Typhoons in China sea; Tropical Cyclones or super cyclones in Indian Ocean; Hurricanes in Caribbean sea; willy-willies in north western Australia.
What is type tropical cyclone?
Tropical cyclone are defined by their region of origin. As the name indicated they are formed in tropical region around the globe.There are two types of cylcones first one is tropical cyclone and later one is temperate cyclone. Unlike temperate cyclone tropical cyclone does not contain warm front and cold front nor it contains warm airmass or cold air mass. It is developed from warm sea water’s latent heat and coriolis force in tropical areas between 5N to 25 N and 5S to 25S in both hemisphere.
How a tropical cyclone is formed?
Initial Formation
The formation and initial development of a cyclonic storm depends upon the transfer of water vapour and latent heat from the warm ocean water to the air, by evaporation from the sea surface.
It encourages formation of vertical cumulus clouds due to convection with condensation of rising air above the ocean surface.
Mature Stage
When a tropical storm escalate, the air rises in vigorous thunderstorms and tends to spread out horizontally at the tropopause. Once air spreads out, a high pressure at high levels is produced, which stimulates the downward motion of air due to convection.
With the inducement of subsidence, air warms up by compression and a warm Low pressure centre is generated which is called Eye of Cyclone.
Decay
A tropical cyclone begins to weaken after its landfall or when it passes over cold waters.
