HEAT TRANSFER…
can be accomplished through
four means:
(2) Phase changes: A liquid evaporates into an overlying gas, a process which
requires energy and therefore removes heat from the liquid. This also occurs often between the
atmosphere and earth’s surface and is known as latent heat flux. The dryness of the desert surface
means it can’t cool through latent heat flux and therefore must cool almost exclusively through
sensible heat flux. The inefficient ventilation of the
desert surface is the reason the deserts are so hot.
