Cloudy, humid days reverse the cooling from both radiation and sublimation — cloud cover prevents snow from emitting energy, and
condensation of water vapor on the snow releases latent heat, warming the snow.
«
Condensation of water vapor over forests creates pressure gradients that have been shown to be sufficient to drive winds that bring moisture from ocean to land.»
Latent heat flux - The flux of heat from the Earth's surface to the atmosphere that is associated with evaporation or
condensation of water vapor at the surface; a component of the surface energy budget.
Some of the cooling is offset by the heat released
by condensation of water vapor, leading temperature to go down at a rate which is currently a little over 6.5 degrees C per kilometer of altitude.
The reason this warms the surface is most easily understood by starting with a simplified model of a purely radiative greenhouse effect that ignores energy transfer in the atmosphere by convection (sensible heat transport) and by the evaporation and
condensation of water vapor (latent heat transport).

condensation of water vapor that occurs because of cooling.
Cloud condensation nuclei: Aerosol particles that provide a platform for
the condensation of water vapor, resulting in clouds with higher droplet concentrations and increased albedo.
It is also known that the nature and size of the particles are important factors in
the condensation of water vapor.

Hurricanes can be thought of, to a first approximation, as a heat engine; obtaining its heat input from the warm, humid air over the tropical ocean, and releasing this heat through
the condensation of water vapor into water droplets in deep thunderstorms of the eyewall and rainbands, then giving off a cold exhaust in the upper levels of the troposphere (~ 12 km / 8 mi up).
