Describe the role of El Nino and Southern Oscillation to control the climate of India. [CBSE 2016]
The periodic change in pressure conditions in eastern Pacific and eastern Indian Ocean is known as the Southern Oscillation. The difference in pressure’in the Indian arid Pacific Oceans is computed to predict the intensity of the monsoons. Negative pressure differences predict below average and late Monsoons. This affects the El Nino, a warm current which flows along the Peruvian current instead of the cold current. The changes in pressure conditions are connected to the EL Nino.
