Practice MCQ for SSC, UPSC, RRB Exams

A. El Nino A.

B. Westerlies B.

C. Trade winds C.

D. La Nina D.

The correct answer is D) La Nina.

Key Details:

La Nina is a climate pattern characterized by the cooling of the sea surface temperature in the central and eastern tropical Pacific Ocean.
This phenomenon has a significant impact on global weather patterns, including the Indian monsoon.
Strengthening the monsoon: During a La Nina year, the trade winds are stronger than usual, which pushes warmer water towards Asia and strengthens the atmospheric circulation that drives the Indian monsoon. This results in above-average rainfall for most of the Indian subcontinent.
Weakening effect: Conversely, an El Nino event (the warming of the same waters) typically weakens the Indian monsoon, often leading to drought-like conditions.
