Question

What is the local wind that blows in the central plain of India during the summer season?
A) Chinook
B) Fohn
C) Loo
D) Bora

Answer 1

Hint: Local winds only blow in a small region at a certain time of day or year. Land Breeze and Sea Breeze are two examples of local winds.

Winds that pass over a small area are known as local winds. Between small low- and high-pressure systems, local winds blast. Local geography has an effect on them. Local winds may be influenced by proximity to an ocean, a lake, or a mountain range.

Complete answer:
Local wind - The process of downslope compressional heating, also known as adiabatic heating, produces hot local winds in most cases. Chinook, Harmattan, Foehn, Sirocco, Norwester, Brickfielder, Khamsin, Santa Ana, Loo, and other hot local winds are examples.

The central plain of India - The Indo-Gangetic Plain, also known as the North Indian Plain, is a large area of the Indian subcontinent extending westward from the combined delta of the Brahmaputra River valley and the Ganges (Ganga) River to the Indus River valley.

Option A) Chinook: Chinook winds, or simply Chinooks, are föhn winds in the interior West of North America, where the Canadian Prairies and Great Plains meet numerous mountain ranges, despite the fact that the term was coined to describe wet, warm coastal winds in the Pacific Northwest. Chinook is a warm, dry, gusty westerly wind that blows down the eastern slopes of the Rocky Mountains and across the western prairies. Hence, this option is incorrect.

Option B)Fohn: In the lee of a mountain range, a föhn also spelt foehn, is a kind of dry, warm down-slope wind. The rain shadow wind is caused by the adiabatic warming of air that has lost the majority of its moisture on windward slopes.
Hence, this option is incorrect.

Option C) Loo: The ‘loo' is a striking characteristic of the hot weather season. During the day, heavy, gusty, hot, dry winds blow across northern and northwest India. They can go on until late at night in some cases. Direct contact with these winds may also be fatal. Hence, this option is correct.

Option D) Bora: Bora is a very strong cold wind that blows from the northeast through the Adriatic Sea, affecting Italy, Slovenia, and Croatia. Hence, this option is incorrect.

Therefore, Option C ‘Loo’ is the correct answer, since Loo is the local wind that blows in the central plain of India during the summer season.

Note: The Indo-Gangetic belt is the world's largest continuous expanse of alluvium, created by silt deposition by numerous rivers. The plains are flat and largely treeless, making canal irrigation a viable option. The region also has a lot of underground water sources.
