Question

mention any two favourable condition for the occurrence of temperature inversion?

Answer 1

ANSWER;__✍️

Temperature inversions ... temperatures increasing with height in the atmosphere ... occur predominantly in two ways. One is the cooling of the atmosphere near the surface when incoming solar radiation declines as the sun goes down, resulting in loss of heat at the surface by outgoing thermal radiation. This is the process by which the so-called "nocturnal surface inversion" is created. It occurs virtually every day, but is inhibited by cloudiness.

The other way temperature inversions are produced is by winds aloft bringing in warm air above a layer of relatively cool air by a process called "differential advection".

It's common for air in the stratosphere to be warmed through absorption of sunlight by ozone, which can result in a temperature inversion at the "tropopause" (that marks the boundary level between the troposphere below and the stratosphere above).

Answer 2

Meaning of Temperature Inversion:

Temperature decreases with increasing altitudes in the troposphere at an average rate of 6.5°C per 1000 metres (normal lapse rate) but sometimes this normal trend of decrease of tempera­ture with increasing heights is reversed under special circumstances i.e., temperature increases upward upto a few kilometres from the earth’s surface. This is called negative lapse rate.
