What is Climate ? Describe the factors affecting the climate of India
Answers
Answer:
Climate is the long-term pattern of weather in an area, typically averaged over a period of 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years
factors affecting climate
Latitude
The Tropic of Cancer crosses the middle of India which begins from the Rann of Kachchh in the west and runs till Mizoram in the east. The states located at the south of the tropic of cancer represent tropical climates, whereas those in the north have subtropical climatic conditions. Hence, India has both tropical and subtropical climates.
Altitude
There are mountains in the north of India. The Himalayas act as a barrier against the cold winds from Central Asia. This causes milder winters in India than in central Asia.
Pressure and Winds
The following atmospheric conditions govern the climates in India:
Pressure and surface winds
Upper air circulation
Western cyclonic disturbances
India lies in the region of northeasterly surface winds. During winters, the subtropical high-pressure belt of the Northern hemisphere leads to the origin of Northeastern winds. The winds blow in the southern direction and get deflected to the right. In winters, high-pressure areas develop over the north of Himalayas. Hence, cold, dry winds blow from the Himalayas towards the low-pressure areas over the oceans in the south.
However, in summers, a low-pressure area develops over northwestern India. Therefore, the wind direction is reversed. Now, the winds move from the high-pressure area over the Indian Ocean to cross the equator and then turn right to reach the low-pressure areas. Since these winds move over the warm ocean, they carry a large amount of moisture leading to widespread rainfall.

Explanation:
Climate is the long-term pattern of weather in a particular area. Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. A region's weather patterns, usually tracked for at least 30 years, are considered its climate
