METHODOLOGY FOR CYCLONE HAZARD ZONATION
Step 1:
Step 2:
The Indian land mass has been divided in to 1 degree Lat X 1
degree Long to blocks. Each block is 111 km X 111 km for
tropical Latitudes. Total number of blocks covering entire Indian
landmass and immediate neighborhood are 277 No’s.
For each block, the number of depressions, cyclonic storms and
sever cyclonic storm have been identified with their intensity and
duration of residency.
