HEAT TRANSFERÉ
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 earthÕs surface
and is known as latent heat flux. The dryness
of the desert surface means it canÕt 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.
