Heat wave and cold wave days in different States of India

Abstract

Criteria for defining heat and cold wave days have been proposed based on human comfort. Using these criteria the extent the Indian sub continent that is affected by heat and cold waves and the frequencies of heat and cold wave days in different states of India. have been presented and discussed. Cold air out-breaks from the continental anticyclone over the Asian main land across the eastern parts of the Himalayan ranges has been suggested as a secondary source of cold waves m northeast India.
