Hot and dry local wind of Northern Plains of India is called:

Question

Accepted Answer

The correct option is 1:

The correct option is 1: Loo

The Loo is a strong, hot, and dry summer wind that blows across the western Indo-Gangetic Plain of Northern India and Pakistan during the late spring and early summer months, typically from April to June. These winds originate from the large landmass of the Thar Desert and the high-temperature regions of Iran and Balochistan. Since the Loo is an intense, dry, thermal wind blowing from west to east, it is a classic example of a local wind system specific to the Northern Plains, characterized by very high temperatures (often exceeding 45°C) and low humidity. Its unique characteristics perfectly match the question's description.

The incorrect option is 2: Monsoon

The Monsoon is a regional wind system and not a local wind. It refers to the seasonal reversal of winds, bringing significant rainfall (South-West Monsoon) to the subcontinent, or dry cool air (North-East Monsoon). The term 'Monsoon' describes a large-scale climatic pattern involving moisture-laden winds, which contradicts the question's requirement for a 'hot and dry local wind'.

The incorrect option is 3: Trade Winds

Trade Winds are planetary, or permanent, global wind systems that blow predominantly from the subtropical high-pressure belts towards the equatorial low-pressure belt (ITCZ). They are vast, persistent winds covering large areas of the tropics and subtropics, and they are neither exclusively hot and dry nor local to the Northern Plains of India, thus distinguishing them from the Loo.

The incorrect option is 4: All options are wrong

Since 'Loo' (Option 1) correctly identifies the hot and dry local wind of the Northern Plains of India, this statement is factually incorrect. The Loo is a well-documented and geographically significant local wind phenomenon in this region.
