Question

Q. Which of the following are favourable conditions for temperature inversion?

Select the correct answers using the code given below:

• A. 1, 2 and 4 only
• B. 2 only
• C. 2, 3 and 4 only
• D. 1, 2, 3 and 4

Answer 1

The correct option is A 1, 2 and 4 only

Explanation:

Favourable Conditions for Temperature Inversion are:

• Long winter nights: Loss of heat by terrestrial radiation from the ground surface during night may exceed the amount of incoming solar radiation.
• Cloudless and clear sky: Loss of heat through terrestrial radiation proceeds more rapidly without any obstruction.
• Dry air near the ground surface: It limits the absorption of the radiated heat from the Earth’s surface.
• Slow movement of air: It results in no transfer or mixing of heat in the lower layers of the atmosphere.
• Snow covered ground surface: It results in maximum loss of heat through reflection of incoming solar radiation.
