Which of the following statements about inversion of temperature is/are correct ?
- 1Temperature increases with increasing altitude.
- 2A long winter night with clear skies is an ideal situation.
- 3It is a short term phenomenon and is common all over the globe except at the poles.
Select the correct answer using the code given below :
General KnowledgeGeography
- A1 and 2 only
- B2 and 3 only
- C1 only
- D1, 2 and 3
Explanation
Temperature inversion means temperature increases with altitude, reversing the normal lapse rate. Long winter nights with clear, calm skies allow maximum radiational cooling of the surface, creating ideal inversion conditions. However, statement 3 is wrong: inversions are common and persistent at the poles, where surface inversions occur frequently. Hence only statements 1 and 2 are correct.
