They believe infrequent bathing helps keep skin hydrated because it avoids
constant evaporation of water, which can be drying.
Not exact matches
The planet when understood, is in
constant change from
water loss to space to distance changes from the sun... but a general assessment
of areas for decades is possible with watching salt ocean patterns as that dictates
evaporation.
But assuming this, given a
constant residence time for
water vapor molecules, the rates
of evaporation and precipitation should rise in step with the absolute humidity.
This number is based on the commonly presented estimate that 0.25 %
of the mass
of the atmosphere is
water vapor, heat
of evaporation of water, and specific heat
of air at
constant pressure.
As you say «Simples» Think
of the ocean as an open pot
of warm
water with
constant heat input (TSI) at a level where
water is held at
constant temperature by
evaporation and internal convection.
Here how it works: Think
of the ocean as an open pot
of warm
water with
constant heat input (TSI) at a level where
water is held at
constant temperature by
evaporation and internal convection.
For example, the atmospheric warming due to increased CO2 might well be expected to increase
water evaporation so as to keep Relative Humidity
constant (albeit raising Specific Humidity), so amplifying the small warming effect
of CO2 itself.
If our idealized reservoir is «U» - shaped (not «V» - shaped) then the surface area remains
constant, irrespective
of the
water level, and so the
evaporation occurs at a
constant (zero - order flux) vs. (dry) temperature.
Note that any extra energy taken by
evaporation from warm air above cooler
water or from warm
water below cooler air will be used to bring forward the timing
of the change
of state
of those molecules already on the cusp
of changing state (there are always many such molecules because
evaporation is a
constant process when the air above the
water is not saturated which is nearly all the time).
