Question 5GS1GS1

Discuss the factors responsible for increased cyclonic activity in the Arabian Sea.

Open scan (p.15)

Main Body

There has been a significant increase in Sea-Surface Temperature (SST) in Arabian Sea which has intensified cyclone activity.

Factors responsible for increased cyclonic activity:

1. Increased temperature on the sea surfaceadds evaporationmore moisture availability
2. Less influx of fresh water from riversenhanced salinity
3. Climate change & global warmingsea level rise

4. Thermocline circulation is changing in the Indian Ocean.

5. Coriolis force is being affected due to sea level riseimpacts counter equatorial current

6. Global conveys belt is undergoing transformation.

7. Melting ice of Arctic and Glaciers of Antarctica are also impacting water density

8. Monsoon changes due to breaks in patterns of evaporation.

9. Higher moisture content in air due to sea warming

10. Low wind shear during time-July and Sept-November.

(Boxed) There is also Geospatial studies reasonable classification:

As a climate globe region, Geographers perspective of closed seaface.

Thus, there has been a rise in cyclonic activity impacting coastal economy & ecology.
