Question

Which part of India does experience the highest diurnal range of temperature and why?

Answer 1

• In Thar desert, the temperature at night drops to near 15°C and during the day time the temperature may rise to 50°C.
• During the same day, the variation between a low temperature and a high air temperature is known as Diurnal temperature variation.
• On the contrary, there is a very small difference or no difference in night and day temperatures in the state of Kerala or in the Andaman and Nicobar islands.

Reason behind highest diurnal range of temperature – Influence of Sea

• People experience extreme weather conditions, as the distance from the sea increases.
• Sea has a moderating influence on the climate.
• The moderating influence on the climate of a location reduces as the distance between the sea and a location increases.
• Continentality is the term that is used to describe this condition.
• Hence there is a huge variation in places like Thar desert as the distance between Thar desert and sea is very high, on the other hand, coastal areas of Kerala, Karnataka, Goa etc do not have very high variation in temperature on the same day.

Factors affecting the Climate of a location

• The six major factors affecting the climate of a location are relief features, ocean currents, distance from the sea, wind and pressure system, altitude, latitude.
