Tibetan plateau has considerable importance with regard to monsoon in Asia. This along with its repeated presence in news makes it a hot topic. In the past few years there have been many research findings regarding – the elevation change in Tibetan plateau, role on Indian monsoon, the change in the glaciers of Tibetan plateau etc.
How Tibetan plateau affects monsoon?
The Tibetan plateau is a vast structure extending long and wide. The heating or cooling of such a large geophysical structure leads to change in the jet streams during summer and winter. The change is the jet streams are due to 1) tilt of the earth changing with season 2) uplift of air from the Tibetan plateau. These changes in the jet stream in winter and summer results in change in wind over the peninsular region. As you would know when wind flow from the equatorial region to the subcontinent, then rainfall will occur. The rate of heating, duration of heating of Tibetan plateau has considerable influence on Monsoon.
The role of the Tibetan plateau has been given in Savindra Singh’s Geography book .In case you have a friend with geo optional, just have a glance over it.
The above psychedelic diagrams shows the flow of jet streams in winter. The lower arm disappears in summer. This results in monsoon flow.
We have been trying to predict the Indian monsoon correctly for years. One of the parameters (among several others) is the Tibetan plateau. So unless we clearly get a knowhow of this parameter, it is difficult to make accurate predictions.
