In my understanding, the direction of wind can be quite differ if that specific location encounter different temperature of air flow. Cold air flows downward according to hot air because it is more dense and sinks while hot air rises. In hot room the air will be much thinner thus reducing the pressure so the air flows from cold room to hot rooms.

I hope this helps.

According to predictions the variation of environmental parameters would be within 5% until 2080 hence we should not expect to see large variations in the wind rose of any particular place. Indeed one could argue that variations would occur at similar rates for any direction of wind velocity.

Dear Ponkumar Ilango,

Always changeable, sometimes more, sometimes less! The general exact answer does not exist.
