As an unsaturated parcel of air rises and cools to its dew point, what is the likely result?
- A.Immediate dissipating-stage thunderstorm
- B.A temperature inversion at the surface
- C.Cloud formation as water vapor condenses
Correct answer
C. Cloud formation as water vapor condenses
Why
Rising air expands and cools, and once it reaches saturation the vapor condenses on microscopic particles to form cloud droplets. This process builds the cumulus clouds a remote pilot watches on convective days.
