1.Energy that intensifies the storm comes from the condensation process in towering cumulonimbus clouds, surrounding center of the storm.
2.Hence, with constant supply of moisture from the sea, storm is further strengthened
3.On reaching land, moisture supply is cut off & the storm dissipates
4.Place where tropical cyclone crosses the land is called landfall of the cyclone
5.Central low pressure is known as eye of the cyclone → Calm with subsiding air having lowest pressure & highest temp.
6.Surrounding this area is zone of strong winds with clouds extending vertically
7.Surrounding the eye is eye wall, a place of strong spirally ascending winds to a height reaching tropopause, having max. wind velocity
