The diurnal temperature range (DTR) is the difference between the daily maximum and minimum temperature. Changes in DTR have multiple possible causes (cloud cover, urban heat, land use change, aerosols, water vapor and greenhouse gases). Different regions are affected by different factors. Some researchers say decrease of DTR is evidence of "climate change". Others say the decrease in DTR leveled off in the 1990s.

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

The north-western part of India comprising the Indian Desert experiences the highest diurnal range of temperature. This is because of the fact that sand (found in ample quantity in this region) gains and loses heat very quickly. As a result of this phenomenon, there is a wide difference between day and night temperatures in this region. The day temperature may rise to 50°C and drop down to near 15°C the same night.


Why is the diurnal range of temperature low in the equatorial regions?

The diurnal range of temperature is low in equatorial regions because these areas receive consistent high levels of insolation throughout the day due to their position near the equator. This leads to minimal variation between daytime and nighttime temperatures. Additionally, the high humidity in equatorial regions helps regulate temperature by trapping heat and maintaining warmth during the night.
