Question

A.The absence of rain
B.Combination of high temperature and excessive humidity
C.Dry hot weather
D.None of the above

Answer 1

Hint:The south-west monsoon starts retreating from northern India in early October. Hence, the months of October and November are known for the retreating monsoon. This retreating monsoon causes rainfall in winters.

Complete answer:
Some parts of the country receive heavy rainfall from this winter monsoon.
The reason behind retreat is that the monsoon trough of low pressure over the Ganga plains becomes weaker as the movement of the sun is Southward. The high pressure replaces the low pressure trough. During this time skies are clear and there's a drop in night temperature. The land remains moist. This combination of high temperature and humidity gives rise to oppressive weather. This is commonly known as 'October heat'. Day temperature rises due to clear skies. clear cloudless sky, high temperature and high humidity is experienced in the month of October. This oppressive weather is referred to as 'October Heat.'There is a transition period between the hot rainy season and cold dry season.Fine weather conditions prevail over the rest of the subcontinent in the end of October and beginning of November.

Hence, the correct answer is option (B).

Note:Tamil nadu ,Odisha,Karnataka (some parts)receive rainfall from retreating monsoon.Most of the region remains dry.October is marked by clear cloudless sky, high temperature and high humidity. As explained earlier, this sultry and oppressive weather is referred to as 'October Heat.'
