Question

The Rainfall that occurs during the winter season is known as ______________.
A. Monsoon
B. Cyclone
C. Mango shower
D. Mavath

Answer 1

HintWinter season comes after southwestern monsoon winds have retreated from north India. This wind reversal starts happening in October and the winter season also experiences the least amount of tropical cyclone activity and depicts the changes in weather.

Complete step-by-step solutionIndia monsoon season is one of its kind. It comes from the direction of the south-west, bringing moisture-laden air from the Arabian sea as a result of low pressure created over northern India at the end of the summer season. The major portion of annual precipitation happens during this time in northern India. But in some southern states, a considerable amount of their annual precipitation happens after the monsoon has started retreating. It happens because of wind reversal during the retreating monsoon. Winds coming from the northeast pass over the Bay of Bengal and pick up some moisture from the air above it and because of its direction, the states which come in contact with this moisture-laden wind, experience rainfall. States of this region, especially Tamil Nadu, experience almost half of its rainfall. South Andhra Pradesh, south-east Karnataka, and south-east Kerala also experience this kind of weather. This phenomenon is known as Mavath in these regions.

Thus, option (D) is correct.

NoteWinter precipitation in northern India is also a phenomenon caused by western disturbance, which is air containing moisture coming from the direction of the Mediterranean Sea. This happens in the states of Haryana, Punjab, Rajasthan, Delhi, and parts of UP. This is also the reason for winter snowfall in the Himalayan belt.
