The cold weather season begins from midNovember in northern India and stays till February. December and January are the coldest months in the northern part of India. The temperature decreases from south to north. The average temperature of Chennai on the eastern coast, is between 24° C - 25° Celsius, while in the northern plains, it ranges between 10°C and 15° Celsius. Days are warm and nights are cold. Frost is common in the north and the higher slopes of the Himalayas experience snowfall.
During this season, the northeast trade winds prevail over the country. They blow from land to sea and hence, for most parts of the country, it is a dry season. Some amount of rainfall occurs on the Tamil Nadu coast from these winds as, here they blow from sea to land.
In the northern part of the country, a feeble high pressure region develops, with light winds moving outwards from this area. Influenced by the relief, these winds blow through the Ganga valley from the west and the northwest. The weather is normally marked by clear sky, low temperatures and low humidity and feeble, variable winds.
A characteristic feature of the cold weather season over the northern plains is the inflow of cyclonic disturbances from the west and the northwest. These low-pressure systems originate over the Mediterranean Sea and western Asia and move into India, along with the westerly flow. They cause the much-needed winter rains over the plains and snowfall in the mountains. Although the total amount of winter rainfall locally known as ‘mahawat’ is small, they are of immense importance for the cultivation of ‘rabi’ crops.

Understanding Winter Rainfall in Northern India
Winter rainfall in northern India is referred to as "mahawat." This term is significant as it pertains to the climatic conditions during the cold weather season, which lasts from mid-November to February. The coldest months, December and January, are crucial for agriculture, particularly for the rabi crops.

... more
- **Cultivation Support**: The small amount of winter rainfall, or mahawat, plays a vital role in the cultivation of rabi crops. These crops are sown in the winter season and harvested in the spring.
- **Irrigation Needs**: Although the total rainfall is limited, it provides essential moisture to the soil, supporting crop growth during the crucial germination phase.

Characteristics of Mahawat
- **Source of Rainfall**: Mahawat originates from cyclonic disturbances that form over the Mediterranean Sea and western Asia. These systems move into India, bringing much-needed precipitation.
- **Weather Conditions**: The weather during this season is typically marked by clear skies, low temperatures, and low humidity, which are conducive for the cultivation of rabi crops.

Conclusion
Thus, option 'C' is correct as it accurately identifies the term "mahawat" as the winter rainfall that is immensely important for the cultivation of rabi crops. Understanding this relationship between climatic conditions and agricultural practices is essential for students studying geography and agriculture in northern India.
