Physical processes• Air converges (tries) to the low pressure areas. Due to Coriolis force it

gets anti-clockwise rotation (in he northern hemisphere).• As air moves to the center of the hurricane it increases the tangential

velocity (to conserve angular momentum):

As “r” decreases v increases. If air could reach the center (r=0) the tangential velocity would become infinity. Diffusion makes that impossible and thus vertical movement occurs some distance away from the hurricane eye.

On the troposphere a outwards flow is generated

But at the troposphere isobaths decrease level, generating
