**Explanation:**

The correct statement about the decrease in rainfall in the Northern Plains is option B - "There is a decrease in rainfall generally from east to west in the Northern Plains."

**Rainfall patterns in the Northern Plains:**

The Northern Plains is a region in India that includes states like Punjab, Haryana, Delhi, Uttar Pradesh, and Bihar. It is characterized by its fertile agricultural lands and is known as the "Breadbasket of India". The region experiences a monsoon climate, with the southwest monsoon bringing the majority of the annual rainfall.

**Factors influencing rainfall distribution:**

1. **Monsoon winds:** The southwest monsoon winds blow from the Arabian Sea and bring moisture-laden clouds. These winds hit the Western Ghats first, causing heavy rainfall along the coastal regions. As these winds move further inland, they encounter the Northern Plains, where the topography plays a significant role in rainfall distribution.

2. **Topography:** The Northern Plains are situated between the Himalayas in the north and the Aravalli Range in the south. The Himalayas act as a barrier to the monsoon winds, causing orographic rainfall on the windward side. As a result, areas near the foothills of the Himalayas receive higher rainfall.

**Rainfall distribution in the Northern Plains:**

The rainfall distribution in the Northern Plains is influenced by the orographic effect and the distance from the coast. Therefore, the correct statement is that there is a decrease in rainfall generally from east to west in the Northern Plains (option B).

- **Eastern regions:** The areas closer to the foothills of the Himalayas, such as Uttarakhand and parts of Uttar Pradesh, receive higher rainfall. This is due to the orographic effect, where the moist winds are forced to rise and cool, leading to condensation and precipitation.

- **Western regions:** As the monsoon winds move further westward, they lose moisture due to the orographic effect and distance from the coast. Therefore, the western parts of the Northern Plains, such as Punjab and Haryana, receive comparatively lower rainfall.

- **North-South variation:** While there may be some variation in rainfall from north to south in the Northern Plains, it is not the dominant factor. The decrease in rainfall is primarily influenced by the east-west distribution.

Therefore, option B is the correct statement as it accurately reflects the decrease in rainfall from east to west in the Northern Plains.

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.

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.
