Consider the diurnal (daily) cycle of temperature at the surface. Why is the tem-
perature maximum in the mid-to-late afternoon?
(a) There is a net energy gain at the surface from dawn to mid-
afternoon.
(b) Clouds form in mid-to-late afternoon, cutting down the solar heating and
cooling the surface.
(c) The intensity of solar radiation is at a maximum at this time.
(d) Late in the day, evaporation from the surface increases and this cools the
surface.
