Question

Explain the difference between diurnal range of temperature and annual range of temperature. Give examples.

Answer 1

Hint: One of them refers to the difference between minimum and maximum temperature of the day. The other refers to average temperature throughout the year.

Complete answer:

S.No	Diurnal range of temperature	Annual range of temperature
1.	The difference between the maximum and minimum daily temperatures is known as the Diurnal temperature range.	The difference between the hottest and coldest months, with monthly mean temperatures, is called the annual temperature range in each case.
2.	There are several potential reasons for increases in this form of temperature (cloud cover, urban heat, land-use change, aerosols, and water vapor and greenhouse gases).	There are several potential causes of changes in this form of temperature that depend on the regions where the temperatures are being measured.
3.	In the Thar Desert, the temperature of the day may rise to 50 degree C and fall on the same night to about 15 degree C. In other areas, such as Karnataka and Maharashtra, there is hardly any difference in day and night temperatures.	In the Northern Hemisphere, the annual temperature variation is larger than that of the Southern Hemisphere.
4.	Different regions are influenced by various considerations. Some experts say that a reduction in DTR is proof of "climate change."	Reduction in Annual range of temperature does not affect climate change.
5.	Diurnal range of temperature is measured by Identify the lowest number, as well as the highest number, in the data collection. The lowest number in the set is subtracted from the highest number. The range of the set of temperature values is the resulting value.	Annual range of temperature is measured by subtracting the average monthly minimum temperature from the average monthly maximum temperature each year.

Note: Example of Diurnal Temperature Range: The difference between the maximum temperature and the minimum temperature in a day. Say max is 35 ° C and min is 18 ° C, then 17 ° C is the diurnal range.
Example of Annual Temperature Range: June average temperature 30 days: (max + min)/2 of daily average temperature 31 days (max + min)/2 of daily average temperature minus December.
