Influence of Southern Oscillation on the Climate of India

The southern oscillation is a pattern of meteorological changes which are often observed between Indian and Pacific oceans.

It has been noticed that whenever the surface level pressure is high over Indian Ocean, it is low over Pacific Ocean and vice-versa.

When the pressure is high over the Pacific Ocean and low over Indian Ocean, the Southwest monsoons’ in India tend to be weaker.

In the reverse case, the monsoons are most likely to be stronger.
