Question

A physical feature that plays a vital role in controlling the winter temperature in India is _______ ?

a. Coastal area
b. Trade winds
c. Monsoon
d. Jet stream

Answer 1

Hint:
A feature of the cold weather season over the northern plains is the flow of cyclonic disturbances from the west and northwest. These low pressure systems originate in the Mediterranean Sea and West Asia and flow rapidly in India. They cause much needed winter rains in the plains on the mountains and for snowfall. In the northern parts of the country, this winter rainfall is locally known as 'Mahavat'.

Complete solution:
The climate of India encompasses a wide range of weather conditions with a wide geographical scale and varied topography, making generalization difficult. The climate in North India is generally warmer than in South India, while South India is more humid due to the nearby coasts. Most parts of the country do not experience temperatures below 10° C (50° F) in winter, and temperatures typically exceed 40° C (104° F) during summer.

Based on the Köppen system, India hosts six major climatic subtypes, including dry deserts to the west, alpine tundra and glaciers to the north, and humid tropical regions supporting rain forests to the southwest and island regions. Many regions have different microclimates, making it one of the most climatic countries in the world.

India's geography and geology are of extreme importance: the Thar Desert in the northwest and the Himalayas in the north work together to form culturally and economically important monsoon regimes. As Earth's tallest and most massive mountain range, the Himalayas stop the flow of indifferent katabatic winds from the icy Tibetan Plateau and Northerly Central Asia. Thus most of North India is kept warm or only mildly cold or cold during winters; The same thermal dam keeps most areas of India warm in summers.

Hence, the correct answer is option C.

Note:
Although the Tropic of Cancer - the boundary that lies between the tropics and subfamilies - passes through the middle of India, the bulk of the country can be considered climatically tropical. The frequency and severity of such climate events are likely to change as a result of human-climate change. Global warming is also considered to be the cause of future vegetation changes, rise in sea level and floods in the low-coastal areas of India.
