The question has been formed from the geography book by Khullar. The Arabian Sea branch of the monsoon is much more powerful than the Bay of Bengal branch because – 1. Arabian sea is larger than the Bay of Bengal and 2. entire Arabian sea current advances towards India, whereas only a part of the Bay of Bengal current enters India.

The Arabian Sea branch of the monsoon is more powerful than the Bay of Bengal branch due to several factors, including the size of the Arabian Sea and the direction of the currents.
Size of the Arabian Sea:
- The Arabian Sea is larger than the Bay of Bengal, which allows it to accumulate more moisture. This results in the formation of stronger and more intense weather systems.
- The larger size of the Arabian Sea also allows it to interact with other atmospheric systems, such as the Somali jet stream and the subtropical jet stream, which further enhance the monsoon activity.
Direction of Currents:
- The entire current of the Arabian Sea advances towards India, while only a part of the Bay of Bengal current enters India.
- The Somali Current, which flows along the coast of Somalia, carries moisture-laden winds from the Arabian Sea. These winds then converge with the southwest monsoon winds over the Indian subcontinent, leading to increased rainfall.
- On the other hand, the Bay of Bengal branch of the monsoon is influenced by the northeast trade winds, which blow across the Bay of Bengal towards Southeast Asia. These winds do not directly contribute to the Indian monsoon, resulting in less rainfall in comparison.
Impact on Rainfall:
- The powerful Arabian Sea branch of the monsoon brings heavy rainfall to the western coast of India, including the states of Maharashtra, Karnataka, and Kerala.
- The Bay of Bengal branch, although comparatively weaker, brings rainfall to the eastern coast of India and parts of Northeast India.
- The Arabian Sea branch is responsible for the majority of the rainfall received by the Indian subcontinent during the monsoon season, making it more influential and powerful.
In conclusion, the Arabian Sea branch of the monsoon is more powerful than the Bay of Bengal branch due to its larger size and the direction of the currents. These factors result in increased moisture accumulation and intense weather systems, leading to heavier rainfall in the western coast of India.
