The Explanation Behind the Reduction of Cyclonic Storm Intensity After Hitting Land

The intensity of most of the cyclonic storm reduces after hitting land. Explain giving suitable reasons.

The intensity of most cyclones reduces after hitting land because land takes away the heat and moisture of tropical ocean water. In order to survive, cyclone storms need evaporation from the warm sea surface. Intensity also decreases because of greater fiction on land, compared to the sea surface.

The intensity of most of the cyclonic storm reduces after hitting land due to the transfer of storm energy to the land because of friction between them and also as the shortage of moisture in land.

Explanation:

The cyclonic storm has very high speed and also a lot of moisture content is present in the cyclonic storms as they are formed from the interior of the ocean.

The cyclonic storms originate by getting energy from the warm tropical oceans and in open space.

The storm originating region should have a constant temperature of about 26.5 °C.

So when these storms with high moisture content and temperature reach the land, the objects on land like houses, trees, bushes, vehicles, and many more hinder the movement of the storm, thus transferring the storm energy to destroy them in the path of the storm.

This causes a frictional force which leads to some loss in the storm strength and the other factor is the difference between the temperature gradient of the land compared to sea level and the absence of moisture in the land also leading to rainfall which in turn weakens the cyclonic storm.
