Monsoon Winds of Arabian Sea| Class 11 Geography Notes

The cold breezes that carry showers with them when they move from the ocean’s surface to the land are known as monsoon winds. India’s environment is fundamentally affected by monsoon winds. The branch monsoon winds over the Arabian Sea are the source of the rainstorm winds. Over the North Eastern Ocean, rainstorm winds begin in the northeast and shift toward the southwest with the changing of the seasons. In the colder time of year, winds begin in Southwest Asia and move toward the ocean.

You will find out about the Arabian Sea monsoon winds from this article, which will assist you with getting ready for the UPSC civil service test in geography.

Monsoon Winds of Arabian Sea

The monsoon winds originating from the Arabian Sea diverge into three main branches:

1. One branch encounters the barrier of the Western Ghats. As these winds ascend the slopes of the Western Ghats to heights of 900-1200 meters, they cool down, leading to heavy rainfall on the windward side of the Sahyadris and the Western Coastal Plain, typically ranging from 250 cm to 400 cm. Upon crossing the Western Ghats, these winds descend and warm up, resulting in decreased humidity and minimal rainfall in the region east of the Western Ghats, known as the rain-shadow area. This phenomenon can be observed in the significant difference in rainfall between Kozhikode, Mangalore, Pune, and Bengaluru.
2. Another branch of the Arabian Sea monsoon strikes the coast north of Mumbai. These winds travel along the Narmada and Tapi river valleys, bringing rainfall to extensive areas of central India. The Chotanagpur plateau receives around 15 cm of rainfall from this branch. Subsequently, these winds enter the Ganga plains and merge with the Bay of Bengal branch.
3. A third branch of the monsoon wind hits the Saurashtra Peninsula and Kachchh. It then traverses west Rajasthan and along the Aravalis, resulting in scanty rainfall. In Punjab and Haryana, this branch also joins the Bay of Bengal branch. The reinforcement of these two branches leads to rainfall in the western Himalayas.

Monsoon winds of the Arabian Sea- Interesting Facts

Let us learn some important points about this topic –

1. In contrast to the trade winds, the monsoon has a throbbing nature that is influenced by various air conditions experienced on its excursion across the warm tropical seas.
2. At the point when the Southwest monsoon winds show up in India in June, the nation encounters its Southwest Rainstorm season, which goes on until mid-September.
3. At the southernmost mark of the Indian landmass, the storm frequently shows up during the first week of June.
4. The Arabian Sea branch and the Bay of Bengal branch are the two divisions that follow.
5. The Arabian Sea branch lands in Mumbai on June 10, about ten days later. This process happens rather quickly.
6. Over the Arabian Sea, monsoon winds originate in the northeast and shift to the southwest with the changing of the seasons.
7. In the winter, winds originate in Southwest Asia and blow toward the sea.
8. While the majority of the wind from the Bay of Bengal flows towards India, the remainder flows towards Myanmar, Thailand, and Malaysia. The entire wind from the Arabian Sea flows towards India.
9. There are three additional branches to the monsoon winds that emerge over the Arabian Sea:
10. One of its branches is blocked by the Western Ghats. These winds climb the 900-1200 m slopes of the Western Ghats.
11. They cool swiftly, resulting in very substantial rainfall (250–400 cm) on the windward side of the Sahyadris and Western Coastal Plain.
12. After passing over the Western Ghats, these winds descend and become warmer. This results in a decrease in the humidity in the breezes.
13. Because of strong winds, the Western Ghats receive very little rainfall. There is not much rain in the rain-shadow area.
14. North of Mumbai, the shoreline is hit by another branch of the Arabian Sea monsoon.
15. In much of central India, these winds, which pass across the basins of the Narmada and Tapi Rivers, produce rain. The Chotanagpur plateau receives 15 cm of rain from this part of the branch.
16. After that, they merge with the Bay of Bengal branch when they enter the Ganga plains.
17. This monsoon wind’s third branch strikes the Kachchh and the Saurashtra Peninsula.
18. After that, it passes into the Aravallis and western Rajasthan, bringing with it barely a little rain.
19. Additionally, it links to the Punjab and Haryana branches of the Bay of Bengal. These two branches, which reinforce one another, are what cause the rains in the western Himalayas.

Conclusion

Around the world, tropical regions between 20° N and 20° S frequently experience monsoons. India’s climate is categorized as monsoon. Most of Asia’s south and southeast have this kind of climate. While just a portion of the Bay of Bengal presently faces India, the entirety of the Arabian Sea wind currently faces Myanmar, Thailand, and Malaysia.

Monsoon winds of Arabian Sea- FAQs

What are the monsoon winds of the Arabian Sea?

What are the main characteristics of Arabian Sea branch of the monsoon?

• They come from the Arabian Sea and hit the western ghats, bringing with them heavy precipitation exceeding 250 cm.
• Another branch of theirs causes very little rain to fall in the Thar desert as it heads northeastern, parallel to the Aravalli highlands.

What is the difference between Arabian Sea and Bay of Bengal Class 11?

The Bay of Bengal is smaller than the Arabian Sea. While only a portion of the Bay of Bengal current penetrates India, the entire Arabian Sea current moves in that direction. The Bay of Bengal branch has greater strength.

What are the two types of monsoon winds?

There are two types of monsoon winds. These are the Southwest monsoon and the Northeast monsoon winds.

What is a short note on monsoon?

A monsoon is a seasonal shift in the predominant, or strongest, winds in a certain area. In much of the tropics, monsoons bring about rainy and dry seasons.
