Where Does Diurnal Temperature Occur?

Diurnal temperature variations are greatest very near Earth's surface. The Tibetan and Andean Plateaus present one of the largest differences in daily temperature on the planet. High desert regions typically have the greatest diurnal-temperature variations, while low-lying humid areas typically have the least.

Why is there diurnal temperature variation at a place?

The variation is greatest very close to the ground and occurs because the thin, dry atmosphere allows the surface to radiate its heat quickly during the night. During dust storms this ability is impaired, and the temperature swing is reduced.

What places experience high diurnal temperature?

The Thar desert area of Rajasthan experiences the highest diurnal range of temperature because it is in the interior part where the temperature differences are very high.
