The lower stratosphere is very much linked dynamically, chemically and radiatively with the upper troposphere, even though the characteristics of these regions are different. We cannot limit our studies in the troposphere, in order to understand monsoon and other weather phenomenon take place in the troposphere. There are very few studies conducted to understand the role of stratosphere in weather and climate. The present study mainly concentrated on the interannual variability of zonal wind, temperature and ozone in the upper troposphere and lower stratosphere in association with Asian summer monsoon with special reference to the Indian context.
