Question

Explain the following term.

Loo

Answer 1

1. The loo is a strong, hot, dry wind that blows across the northern plains of the Indian subcontinent during the pre‑monsoon hot season (roughly March - May). It originates over heated land and arid regions, is strongest in the afternoons, and raises daytime temperatures dramatically while lowering humidity. Loos are driven by intense surface heating that creates a thermal low, drawing air from surrounding dry areas; they may carry dust and cause sudden heat‑spells.
2. Health and environmental impacts include heatstroke, dehydration, crop stress, wilting, and increased evaporation; they also worsen air quality when dusty. Local coping measures include staying indoors during peak hours, drinking fluids, wetting roofs and walls, and shading exposed areas. Meteorological studies and school geography texts often mention the loo when describing seasonal climate patterns in northern India.
