Question

write a short note on trophical cyclones?

Answer 1

Tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain. Drawing energy from the sea surface and maintaining its strength as long as it remains over warm water, a tropical cyclone generates winds that exceed 119 km (74 miles) per hour. In extreme cases winds may exceed 240 km (150 miles) per hour, and gusts may surpass 320 km (200 miles) per hour. Accompanying these strong winds are torrential rains and a devastating phenomenon known as the storm surge, an elevation of the sea surface that can reach 6 metres (20 feet) above normal levels. Such a combination of high winds and water makes cyclones a serious hazard for coastal areas in tropical and subtropical areas of the world.

Answer 2

$\textbf{Cyclone}$:

A small low pressure system with very high speed winds revolving around it is called cyclone.

$\textbf{How Cyclones Forms ? }$

The most air over the sea and ocean gets heated by sun rays and rises up creating a low pressure region. This warm air get cool and starts condensing.

During condensation heat is released and air around it gets warm. This warm air rises upwards creating a low pressure region.

This space is filled by cooler air. This cycle of events continue till a very low pressure system with very high speed winds revolving around it is formed. This forms cyclone.
