Rajesh sir, please comment on Mumbai climate. Winter is not felt this year except few days.
Are we going to experience chill or be ready for next summer??

North East Monsoon refuses to end. What will happen to south west monsoon this year.
It will be delayed. This will accelerate the desertification of Maharashtra and Gujarat.

This phenomena needs to be studied.

Saurabh: NE Monsoon delay will have no effect on the SWM.. SWM can be affected by delay of WDs into end May... As regards desertification... :-)
