Principles of Building Planning MCQ with answer and solution

Concept

Prevailing monsoon wind direction in India

Formula

NONE

Step-by-step solution

1. In India, summer heating creates a low-pressure area over the mainland, drawing air from the Indian Ocean. 2. These prevailing monsoon winds travel from the south-western direction towards the north-east. 3. Therefore, the wind direction during summer and monsoon in India is South-west. Answer: C

Explanation

In India, the prevailing summer and monsoon winds originate over the Indian Ocean and travel toward the mainland from the south-west. These moist winds carry the seasonal rainfall crucial for the region's climate and agriculture. Designing buildings with this wind direction in mind allows for effective natural ventilation during hot and humid months.

Why the other options are wrong

A) North-east represents the prevailing wind direction during the winter monsoon season. B) South-east is not a primary prevailing wind direction during the summer monsoon in India. D) North-west is associated with winter winds or local disturbances rather than the summer monsoon.

Shortcut

India's summer and monsoon winds originate from the South-West (SW).

Common mistake

Confusing the prevailing South-West summer monsoon wind direction with the North-East winter monsoon.
