why is the eastern coast line more vulnerable to the cyclones than the western coast line in Indian Subcontinent?
Answers
Answer:
Indian subcontinent is one of the worst cyclone affected areas in the world. Unfortunately almost 80 percent of the cyclones hit the eastern coast only. The reasons for this difference in hit ratio can be following:-
(a) Temperature:- BOB is hotter than Arabian sea. Hot water temperature is the basic criteria for the development & intensification of cyclones.
(b) Salinity:- Arabian sea has higher salinity than BOB. Its easier to heat & simultaneously evaporate water having lower salinity.
(c) Location:- The typhoons originating in the Pacific ocean too influences the cyclones in BOB, not the case in Arabian sea.
(d) Movement:- According to IMD cyclones originating in Arabian sea are believed to move northwest. So they actually move away from Indian mainland.
Being a natural calamity it can not be avoided but only mitigated. Following are some measures of mitigation:-
(a) Early warning systems can be made more robust & error free to provide correct real time data.
(b) Any kind of residential colonies or hotels should be avoided near the coastline. Or if already constructed, must be evacuated as early as possible.
(c) Every village & city must have a crisis centre with basic amenities, so that people can take shelter at the time cyclones hit.
(d) Saving the lives of domesticated animals should also be on the checklist.
(e) Every city must have enough channels for the rain water to get away.
Explanation:
With the worsening environmental condition, the nature of cyclones is going to be difficult to predict. Although with the above measures we can prepare ourselves to face the calamity & restrict the damage to the minimum
