Which of the following is a major factor in the weakening of a tropical cyclone?
A. Cold ocean waters
B. Weak wind shear
C. High humidity
D. Warm ocean waters
Answer: Option A
Solution (By JKSSB Mock Tests)
Tropical cyclones weaken when they move over cold ocean waters, encounter strong wind shear, make landfall, or move into areas of high vertical wind shear, which disrupts their structure.
Explanation:
The troposphere is characterized by decreasing temperature with altitude (normal lapse rate) due to adiabatic cooling, and it contains most of the weather phenomena.
Explanation:
Cold fronts are characterized by a steep temperature gradient (rapid temperature drop), strong winds, heavy rain, and thunderstorms, and they move faster than warm fronts.
Explanation:
The Bay of Bengal is more prone to tropical cyclones than the Arabian Sea, with cyclones frequently forming during the pre-monsoon and post-monsoon seasons.
