Question

Why does temperature in Mumbai and Chennai not fall as low as it does in Delhi?

Answer 1

Hint: To solve this we must know about the geographical locations of Mumbai, Chennai and Delhi. Mumbai and Chennai are near to sea bodies whereas Delhi is not nearer to sea body. Thus, Mumbai and Chennai are said to be coastal areas as they are near the sea coast.

Complete step-by-step answer:
We know that Mumbai and Chennai are near to sea bodies whereas Delhi is not nearer to sea body. Thus, Mumbai and Chennai are said to be coastal areas as they are near the sea coast.In coastal areas, the climate is moderate throughout the year. This is because the sea surface absorbs heat slowly and also loses heat slowly thus influencing the temperature of the adjacent land.

Mumbai and Chennai are along the sea coast and thus, Mumbai and Chennai have maritime climate or oceanic climate. The sea tones down the extreme climatic conditions. Also, it rains heavily in Mumbai and Chennai. The rains bring down the coldness and dryness to a great extent.

The sea breeze blowing during the day reduces the day time temperature of the coastal areas.
Thus, as Mumbai and Chennai are located near sea bodies, the temperature in Mumbai and Chennai does not fall as low as it falls in Delhi. Thus, the temperature in Mumbai and Chennai does not fall as low as it does in Delhi because Mumbai and Chennai lie near the sea coast.

Note: Also, the specific heat capacity of water is high. Thus, the presence of large amounts of water modifies the climate of the nearby lands. This makes the adjacent lands warmer in winter and cooler in summer. Thus, as Mumbai and Chennai lie near sea bodies the temperature in these areas does not fall to a very low level.
