Impact of the upper tropospheric cooling trend over Central Asia on the Indian summer monsoon rainfall and the Bay of Bengal cyclone tracks
The Indian summer monsoon rainfall had a threedecade long alternate dry and wet epochs during about 150 years from 1840 to 1989. The dry epochs resulted in frequent drought monsoons affecting agriculture, power generation and the overall economy of the country. A high percentage of severe cyclones in the Bay of Bengal moved northwards during the dry epochs causing disasters in Bangladesh, Myanmar and the Indian States of Odisha and West Bengal.
