An air parcel having 40°C temperature moves from ground level to 500 m elevation in dry air following the “adiabatic lapse rate”. The resulting temperature of air parcel at 500 m elevation will be
-
- 35°C
- 38°C
- 41°C
- 44°C
Correct Option: A
Adiabatic lapse rate = 9.8°C/km
∴ Fall in temperature = 0.5 × 9.8 = 4.9°C
∴ Resulting temperature = 40 – 4.9 ≈ 35°C.
