Which of the following is the primary reason for the formation of coastal deserts?
A. Subtropical high pressure
B. Rain shadow effect
C. Cold ocean currents
D. Monsoon winds
Answer: Option C
Solution (By JKSSB Mock Tests)
Coastal deserts, such as the Atacama and Namib Deserts, form primarily due to cold ocean currents that cool the air, suppress evaporation, and stabilize the atmosphere, preventing rainfall.
Explanation:
The 'Burst' of the monsoon refers to the sudden and abrupt onset of heavy rains that marks the beginning of the monsoon season after a period of pre-monsoon showers.
Explanation:
A negative IOD event is characterized by warmer than normal sea surface temperatures in the eastern Indian Ocean and cooler than normal in the west. This often leads to increased rainfall over Indonesia and Australia and reduced rainfall over East Africa.
Explanation:
The Indian monsoon is influenced by multiple factors, including El Niño-Southern Oscillation (ENSO), the land-sea temperature contrast (which creates a thermal low over Asia), and the movement of the Intertropical Convergence Zone (ITCZ).
