Simultaneously, as the
average liquid droplet becomes smaller through
evaporation, the vapor's density increases, so more vapor molecules merge at a faster
rate to become microscopic liquid droplets, and more water molecules are ionized.
Average annual rainfall is measured at 3,560 mm with an
evaporation rate of 1,708 mm per year.
The
rate of
evaporation at 21 C is about 88 Joules per sec which if that was
averaged over a large enough area would be about 88 Wm - 2 per sec.
Rates of water loss, due in part to
evaporation, were double the long - term
average.
The steady increase in global temperatures, including
average temperatures in Australia, means that even when rainfall is at or near the historical
average, conditions are drier than before because
evaporation rates are higher.
The TEMPERATURE of the water (its
average kinetic energy) determines the
rate of both
evaporation and radiation.
Instead it is a composite of the
rates of
evaporation and condensation, melting and freezing and thus the
average time that a water molecule remains in the air in vapour form, or in the ocean as a liquid or in ice and snow as a solid.
