प्रश्न
Why does the Tamil Nadu coast get rainfall in October?
उत्तर
The south-west monsoon begins to withdraw from India by the first week of October. It leaves Jammu-Kashmir, the Northern Plains, then peninsular India, moving southwards and westwards. When it reaches the Chennai coast on its way backwards, it is checked by the Eastern Ghats and imparts rain to the Chennai coast. Chennai gets about 60 cm of rain from the retreating monsoon.
