Hot local wind that flows over north India in summer is known as:

Correct option is A

The correct answer is (a) Loo.

The Loo is a strong, hot, and dry summer wind that blows over the Indo-Gangetic Plain region of North India and Pakistan during the months of May and June. Originating from the west, these winds are characterized by extremely high temperatures, often ranging between 45°C and 50°C (113°F to 122°F). Exposure to the Loo can lead to severe heatstrokes and dehydration, making it hazardous for humans and animals.

• Impact on Vegetation: The Loo's high temperatures and low humidity have a severe drying effect on vegetation, leading to widespread browning in the affected areas during May and June.

• Cultural Significance: In popular Indo-Pakistani culture, the Loo is sometimes referred to as an "evil wind" due to its dangerous effects. Traditional cooling drinks, such as sharbats made from rose, khus-khus, shahtoot, bel, and phalsa, are consumed during this season to mitigate its impact.
