Q- What do you understand by the phenomenon of ENSO?

Answer- ENSO normally refers to when the tropical eastern South Pacific Ocean experiences high pressure, the tropical eastern Indian Ocean experiences low pressure. But bin certain years, there is a reversal in pressure conditions and the eastern pacific has low pressure in comparison to the Indian Ocean. The periodic change in the pressure conditions is commonly known as Southern Oscillation (SO). The difference in pressure over Tahiti, in the Pacific Ocean and Darwin in the northern Australia is computed to predict the intensity of the monsoon.

A feature connected with the SO is called E1 Nino. It plays a big role in SO, the warm ocean current that blows at past of the Paruvian coast, in place of the cold Paruvian current every 2 to 5 years.
