Answer 2

Answer:

The Malabar coast lies on the Western Ghats while Tamil Nadu or Madras (Now Chennai) lies on the Eastern Ghats on the Coromandel coast. In the month of July, it so happens that when the north-east monsoon arise from the Arabian sea and first of all strike against the Western Ghats it rains heavily on the Malabar coast. When these a monsoon leave the Western Ghats they already deprived of much of their moisture and by the time thēy reach the Eastern Ghats after covering a long distance they are completely dry and as such there is almost no rain on the Eastern Ghats in the month of July. Hence, when it is raining heavily on the Malabar coast, Chennai is comparatively dry.
