We drink more water during summer and
do not drink the same amount of water during winter. Why do we wear
cotton or lighter clothes during summer season and heavy woollen clothes
during cold weather season in north India? Why do not we wear woollen
clothes in south India? This is because of the prevalence of
varying weather conditions between north and south India.The southwest monsoon begins to retreat from north India by the end of September due to the southward shifting pressure belts. The southwest monsoon wind returns from Indian
landmass and blows towards Bay of Bengal. The coriolis force deflects this wind and makes it to blow from northeast. Hence, it is known asNortheast monsoon or Post-monsoon season.The season is associated with the establishment
of the north-easterly wind system over the Indian subcontinent. Andhra Pradesh, Tamilnadu, Kerala and south interior Karnataka receive good amount of rainfall accounting for35% of their annual total. Many parts of Tamilnadu and some parts of Andhra Pradesh and Karnataka receive rainfall during this season due to the storms forming in the Bay of Bengal.Large scale losses to life and property occur due to heavy rainfall, strong winds and storm surge in the coastal regions. The day time temperatures start falling sharply all over the country.

These are found in the areas with 100 to200cm. annual rainfall. These are called
‘Monsoon Forests’. The mean annual temperature of this region is about 27 o C and
the average annual relative humidity is 60 to70 percent. The trees of these forests drop their leaves during the spring and early summer. (SubHimalayan - Region from Punjab to Assam,Great Plains- Punjab, Haryana, Uttar Pradesh,
Bihar, West Bengal, Central India - Jharkhand,Madhya Pradesh, Chattisgarh, South India -Maharashtra, Karnataka, Telangana, Andhra Pradesh, Tamilnadu and Kerala states are notable for this type of natural vegetation.)Teak and sal are the most important trees.Sandalwood, rosewood, kusum, mahua, palas,haldu, amla, padauk, bamboo and tendu arethe other trees of economic importance. Theseforests also provide fragrant oil, varnish, sandal oil and perfumes These are found in the areas with 50 to 100 cm. annual rainfall. They represent a transitional type of forests. These are found in east Rajasthan, Haryana, Punjab, Western Uttar Pradesh, Madhya Pradesh, Eastern Maharashtra, Telangana, West Karnataka and
East Tamilnadu. The important species are mahua, banyan, amaltas, palas, haldu, kikar, bamboo, babool, khair etc.,
