Question

Between the cities of Mumbai and Jaisalmer, which place will have a higher diurnal range of temperature? Why?

Answer 1

Jaisalmer will have a higher diurnal range of temperature compared to Mumbai. This is because Jaisalmer is located in a desert region with a continental (extreme) climate, where the land heats up very quickly during the day and cools down rapidly at night, leading to large temperature differences between day and night.

In contrast, Mumbai is a coastal city with a maritime (moderate) climate, influenced by the sea, which heats and cools slowly. The sea’s moderating effect, along with the presence of humidity and sea breezes, keeps the temperature relatively stable throughout the day and night, resulting in a smaller diurnal temperature range.

Thus, the absence of the sea’s moderating influence and the dry, sandy surface in Jaisalmer causes a much higher temperature variation between day and night than in Mumbai.
