Q. Which of the following are favourable conditions for the occurrence of heat waves?- Transportation of hot dry air over a region
- Absence of moisture in the lower atmosphere
- The sky should be practically cloudless
- Large amplitude cyclonic flow over the area
Select the correct answer using the codes given below:
Answer:
Only 1 & 3
Notes: Heat waves favor conditions such as transportation of hot, dry air and a practically cloudless sky, which increase insulation. Absence of moisture in the lower, not upper, atmosphere favors heat waves. Large amplitude anti-cyclonic, not cyclonic, flow favors heat waves. Therefore, only statements 1 and 3 are correct.
