Hurricane storm

​

Hurricane storm usually comprises of two circular convergent channels of flowing air starting some 500 kilometers from the hurricane's center and ends at the hurricane's center (the “eye”).

 

Warm humid air (30 deg. celsius) at the hurricane's perimeter, flows and accelerates in convergent channels, towards the hurricane's “eye”, becomes colder, thus generates clouds. this phenomenon is according to Bernoulli's energy conservation law:

 

 

 

Where:        is air thermal energy per unit mass, and         is air kinetic energy.

     

This law states that the sum of kinetic energy and thermal energy of a gas in isentropic flow (without energy exchanges with the surrounding) is constant, and the thermal energy can be converted into kinetic energy, as demonstrated by a hurricane storm
