WHAT ARE CYCLONES AND ITS TYPES

WHAT ARE CYCLONES ? & ITS TYPES [ EVERY DAY SCIENCE] CSS/PMS/FPSC/PPSC

The whirlpools formed due to low air pressure [ P= F/A ( force per unit Area) ] are known as cyclones. When air moves upward due to heat it produces low air pressure there. Therefore, air moves from areas of high pressure to the areas of low pressure, which makes cyclones. The centres and surrounding of cyclones heavy clouds and there are heavy rains. If a sudden change occurs in air pressure of cyclones or distance among isobars reduces then strong winds move severe rainfall occurs. These cyclones are the cause of rainfalls in Balouchistan of Pakistan.(https://eastwestknowledge.com/cyber-crime/)

TYPES OF CYCLONES.

There are following types:

[1] WHAT ARE TROPICAL CYCLONES ?

These are formed on oceans. These are mostly formed between 8-15 degree latitude in North-south. These are disastrous in nature and destroy the areas in their way. On the south eastern coasts of Pacific Ocean they are known as Hurricane. They are known as Tropical cyclones in Indian Oceans where they are formed in Bay of Bengal. These hurricanes leave severe effects on India and Bangladesh. They cause severe loss of loves and material in coastal areas.

[2] WHAT ARE TEMPERATE CYCLONES ?

These flow from North to South in 40 to 70 degree latitude. These usually cover large areas. They flow along Western winds. The main reason of temperate formation is the collision between cold Polar and a bit hot sub-polar wind. This collision makes a polar front. Eventually hot air moves upward and a cyclone condition happens. Sub-polar low pressure belt is also created due to these.

[3] WHAT IS TORNADO ?

Tornado is a small cyclone whose central part consist of a small area. In this central part, winds flow very fast. These are heavy black clouds in centre. Tornadoes make disaster in Northern America and some parts of Australia. Humidity, dust and other materials add in the central part of tornado and nothing is visible.(https://oceanservice.noaa.gov/facts/cyclone.html)
