If there were no Himalayas, what would the climate be like in China and India?

There are no Himalayas. Not just the United States, China and India. The climate will become very bad. The climate of the whole human earth will also become very bad. Himalayas is the highest mountain range in the world, located in the south of Qinghai-Tibet Plateau. The Himalayas were formed by the collision and extrusion of the Eurasian plate and the Indian Ocean plate. The Himalayas used to be a part of Wang Yang, and the Indian Ocean plate dived from the Yarlung Zangbo River to the Eurasian plate. The strong extrusion uplifted the Eurasian continent and formed the "world backbone" that we are familiar with.

Himalaya is not only the "backbone of the world", but also China and India. Natural borders of Nepal, Pakistan, Bhutan and other countries. There is little rainfall in northern China, and some areas even become uninhabited deserts. Why is this? This is because the Himalayas block most of the humid sea breeze from South Asia. India has a large rainfall, and it is precisely because of the blocking of the Himalayas that it can only stay in India, so that Indian crops can fully grow!

Without the barrier of Himalayas, due to the strong wind in the south, the geographical morphology of the north and south sides of the mountain will tend to be the same. There will be no polarization of rainfall. The arid desert in the northwest will bring abundant rainfall and make water plants flourish!

Besides the ocean wind from the south, there is also the cold wind from the north. Without the barrier of the Himalayas, the cold wind would pass through India. Then the dense population structure in northern India will become scarce. And China will not be killed by the Himalayas! Whether the Himalayas exist or not has advantages and disadvantages. The existence of the Himalayas is a natural choice, which cannot be changed, but can only be adapted.
