THE RETREATING MONSOON
The period is from mid-September to mid-December. It marks transitional weather conditions between hot-wet and cool-dry weather. The south-westerly monsoon winds gradually retreat. Owing to the prevalence of high temperature-about 24°C-there is a period of hot weather called 'October Heat'. Due to westerly jet-stream, cyclonic rainfall is experienced in October. Violent tropical cyclone is also formed in Bay of Bengal and Arabian Sea. It causes great destruction in Godavari and Krishna deltaic regions.
The retreating monsoon is responsible for winter rainfall in Coromandal coast (Tamil Nadu) due to exclusive local relief factors.
