Explain the characteristic features of summer and winter seasons of Tamil Nadu. Summer Seasons:
Answer:
The apparent migration of the sun towards north during March, April and May result in the reception of vertical sun’s rays by South India. Thus there is a steady rise in temperature from the equator. Hence, Tamil Nadu located to the south of Tropic of Cancer experiences high temperature. Generally, the temperature varies from 30°C to more than 40°C. During this season particularly in the month of May, the southern part of the state receives some rainfall from pre-monsoon showers (Mango/Blossom showers) and some parts experience convectional rainfall.
Winter Seasons:
During January’ and February, the vertical rays of the sun fall between the Tropic of Capricorn and the Equator. Hence, Tamil Nadu and India on the whole receive slanting rays from the sun. So, the weather is slightly cooler during these months. The difference between summer and winter temperature is not very high. Winter temperature in Tamil Nadu varies from 15°C to 25°C. However, in the hill stations, the winter temperature drops below 5°C occasionally. Some valleys in the Nilgiris record even 0°C.
