Answer 1

The correct option is B When rain fails to occur for one or more weeks during the southwest monsoon period after having rained for a few days.

Explanation:

Break/Burst of the Monsoon

The rain in the southwest monsoon season begins rather abruptly. One result of the first rain is that it brings down the temperature substantially. This sudden onset of the moisture-laden winds associated with violent thunder and lightning is often termed as the “break” or “burst” of the monsoon.

Break in the Monsoon

If rain fails to occur for one or more weeks during the southwest monsoon period after having rained for a few days.

These breaks in the different regions are due to different reasons:

• In northern India, rains are likely to fail if the rain-bearing storms are not very frequent along the monsoon trough or the ITCZ over this region.
• Over the west coast, the dry spells are associated with days when winds blow parallel to the coast.
