Question

The deepest radiation inversion would be observed:
A.At the equator any day of the year.
B.In polar regions in the winter.
C.At the top of a high mountain in winter.
D.On a desert in winter.

Answer 1

Hint: Radiation inversion is the process by which a cold layer of air gets formed, just adjacent to the ground surface which is cooled down by the loss of radiation or heat which increases with the increase of height and air temperature.

Complete answer:In meteorology, radiation inversion is a process in which normal atmospheric conditions or characters change from the ground with the increase in height or altitude. Normally, air temperature decreases with the increase in height. But during radiation inversion, hotter air is kept above the cold air and the normal temperature profile of the area gets inverted with the increasing height. Hence, inversion will happen.
Radiation inversion generally happens in the areas where cools off a lot at night times. There during the night, the ground cools off and heat will radiate to the sky and
Radiation inversion may also lead to the trapping of air pollutants, smog, and dust particles if the humidity levels of the area are high. This may also lead to harmful disasters. It may also notoriously result in the freezing of rainwater in cold climates.
Thus, we can say that the deepest radiation inversion can be observed in polar regions in the winters. So, option ‘B’ is the correct option.
Inversion is a rare condition and cannot happen on a daily basis. Thus, the other three options are neglected.

Note:It is a very rare condition when elevated radiation inversions form because cooling creates a relatively low in potential temperature at some heights above the surface which would cause cool air to decrease from the inversion, which will create turbulence that has the capability to destroy the inversion.
