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.
