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 lot of moisture content is present in the cyclonic storms as they are formed from interior of ocean.

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

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

So when these storms with high moisture content and temperature reaches the land, the objects in land like houses, trees, bushes, vehicles and many more hinders the movement of the storm, thus transferring the storm energy to destroy them on the path of 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 land compared to sea level and the absence of moisture in the land also leading to rain fall which in turn weakens the cyclonic storm.
