Solution

Diurnal range of temperature and annual range of temperature are the two different kinds of temperature. As the name suggests ‘Diurnal’ implies daily, while ‘annual’ implies yearly. Let us know the difference between the two ranges of temperature.

Difference between diurnal range of temperature and annual range of temperature

The difference between the diurnal range of temperature and annual range of temperature is tabulated below

Diurnal range of temperature Annual range of temperature

The difference between the daily maximum and minimum temperature is called Diurnal range of temperature. The difference between the hottest and coldest months, taking monthly mean temperatures in each case is called the annual range of temperature.

Changes in this kind of temperature have multiple possible causes (cloud cover, urban heat, land-use change, aerosols, water vapour and greenhouse gases). Changes in this kind of temperature have multiple possible causes that depend on the regions where the temperatures are being measured.

In the Thar desert, the day temperature may rise to 50ºC and drop down to near 15°C the same night. whereas, there is hardly any difference in day and night temperatures in other places like Karnataka and Maharashtra. The annual range of temperature is greater in the Northern Hemisphere than that in the Southern Hemisphere
