Which of the following is/are the ideal conditions for temperature inversion to occur? A. Cloudy skies B. Calm and stable air C. Long summer days Select the correct answer using the codes given below: Correct Answer B only

The correct answer is B only.

Key Points

  • The Ideal conditions for temperature inversion are:
    • Long hours, so that it is greater than the incoming radiation than the outgoing radiation.
    • Clear skies that allow radiation to escape unhindered.
    • Calm and stable air, such that, at lower speeds, there is no vertical mixing.
  • A temperature inversion is the reversal of the natural temperature activity in the troposphere, where a layer of cool air on the surface is replaced by a layer of warmer air. (The temperature normally decreases with height under normal conditions).

Additional Information

  • An inversion serves as a limit on the airflow from the layers below upwards. As a consequence, the convection produced by air heating from below is limited to levels below the inversion stage.
  • Likewise, the diffusion of dust, smoke, and other air contaminants is reduced.
  • Convective clouds do not rise high enough to create showers in regions where a pronounced low-level inversion is present.
  • Owing to the accumulation of dust and smoke particles, visibility can be significantly diminished under the inversion. Since the air at the base of inversion appears to be cold, there is sometimes fog.
