Which of the following is the primary reason for the low rainfall in the rain shadow region of the Eastern Ghats? MCQ with Answer and Explanation

Explanation:
The Southern Oscillation Index (SOI) is a measure of the difference in sea level pressure between Tahiti (central Pacific) and Darwin (northern Australia). A negative SOI indicates El Niño conditions, while a positive SOI indicates La Niña conditions.

Explanation:
The Eastern Ghats receive rainfall from the Northeast Monsoon (October-December), as the winds pick up moisture from the Bay of Bengal.

The Indian monsoon is driven by the differential heating of the Asian landmass and the Indian Ocean, creating a large pressure gradient that causes moisture-laden winds to blow from the sea to the land.
