From where does monsoon rain come in Bihar?
The correct answer is option 'C', the Bay of Bengal.
Explanation:
Monsoon rain in Bihar is primarily influenced by the Bay of Bengal branch of the southwest monsoon. Here is a detailed explanation of the factors that contribute to monsoon rain in Bihar:
1. Southwest Monsoon: The southwest monsoon is a seasonal wind system that brings abundant rainfall to the Indian subcontinent during the summer months. It is characterized by moisture-laden winds blowing from the southwest direction. The southwest monsoon is divided into two branches: the Arabian Sea branch and the Bay of Bengal branch.
2. Bay of Bengal: Bihar, being an eastern state in India, falls under the influence of the Bay of Bengal branch of the southwest monsoon. The Bay of Bengal is located in the northeastern part of the Indian Ocean and is surrounded by India, Bangladesh, Myanmar, and Sri Lanka. The warm and moist air currents originating from the Bay of Bengal bring rain to Bihar during the monsoon season.
3. Moisture Transport: The Bay of Bengal branch of the southwest monsoon carries moisture-laden winds from the Bay of Bengal towards Bihar. As these winds encounter the landmass, they rise, cool down, and condense, resulting in the formation of clouds and subsequent rainfall. The proximity of Bihar to the Bay of Bengal makes it vulnerable to heavy monsoon rainfall.
4. Orographic Effect: The Himalayan mountain range, located to the north of Bihar, also plays a role in influencing monsoon rainfall in the region. The Himalayas act as a barrier for the monsoon winds, forcing them to ascend and release moisture in the form of rain. This orographic effect enhances rainfall in Bihar and other regions located in the foothills of the Himalayas.
In summary, the monsoon rain in Bihar primarily originates from the Bay of Bengal. The moisture-laden winds from the Bay of Bengal, driven by the southwest monsoon, bring rainfall to Bihar during the summer months. The proximity of Bihar to the Bay of Bengal and the orographic effect of the Himalayas contribute to the heavy monsoon rainfall experienced in the region.

- Rainfall in Bihar is mainly due to southwest monsoon winds coming from the Bay of Bengal.
- These winds cause 85% of the total annual rainfall of Bihar.
- Based on the latitudinal extent of the state, it is situated in a sub-tropical climate.
- The eastern part of Bihar has a humid climate and the western part has a semi-arid climate.
IMPORTANT FACTS-:
- Due to its proximity to the Bay of Bengal, the cyclones coming from the Bay have a special effect on the climate of the state.
- In the summer, the low pressure that develops in the region of Rajasthan extends from Bihar, Jharkhand to Orissa in the east.
- Due to being situated in the path of the winds blowing from the Bay of Bengal towards this low pressure, it rains in the state of Bihar.
CONFUSING POINTS-:
- Bihar receives rainfall during the monsoon due to the southwest monsoon.
- The rainy season is from June to September.
- Monsoon winds start on June 8 in the eastern part and June 15 in the western part.
- When a high-pressure centre develops over the northern Bay of Bengal, a low-pressure centre develops over the plains.
- The highest rainfall in the plains occurs in Kishanganj district, where the average rainfall is 2177 mm.
