Chapter 31, Problem 5RAT

When upper regions of the atmosphere are warmer than lower regions we have

(a) convective lifting.

(b) a temperature inversion.

(c) absolute instability.

(d) an adiabatic process.

To determine

The correct option for the statement “When upper regions of the atmosphere are warmer than lower regions we have”

Answer to Problem 5RAT

The correct option for the statement “When upper regions of the atmosphere are warmer than lower regions we have” is an option (b).

Explanation of Solution

A temperature inversion is the unexpected change in the temperature of the atmosphere along with the altitude and the visibility through the layer, clouds forms, and precipitation are explained in terms of this process.

The tropospheric region where most of the clouds formed, the temperature inversion can be observed as the warm layers move over the cool layer of air and it ceases the upward movement of the air.

The result of temperature inversion is that the convection is produced by the heat of the air from below to some limits. The visibility gets reduced mostly below the inversion and convective clouds cannot grow high enough to form showers.

Conclusion:

Therefore, the correct option for the statement “When upper regions of the atmosphere are warmer than lower regions we have” is an option (b).
