As the Jet Stream dip became more oriented toward the East Coast during March, storms that would ultimately blow up over the Atlantic at first got a big plug of moisture
from the extra evaporation flowing off that warmer than normal Gulf.
It just goes either into more evaporation or to reduce the deficit
from the extra evaporation the DLR has already induced.
Not exact matches
The Realclimate theory thus fails and the temperature gradient
from the body of the ocean to the top millimetre and then the atmosphere is maintained at or near to the natural level with the
extra warmth being ejected
from the system by the enhanced
evaporation / condensation and weather processes.
The lack of» water vapor» is, because: it was more water in Arctic ocean without ice cover as» insulation» - > water absorbed
extra coldness and the currents brought
extra coldness in North Atlantic = above the ocean is colder = less
evaporation - > less water vapor produced - > less moisture going west
from central Atlantic.
The claim that this is
from the
extra «back radiation»
from more CO2 is the scientific equivalent of bollocks because IR causes more
evaporation, not temperature rise.
If the energy required for the
extra evaporation does all or mostly come
from the water then as I have explained it has the potential to more than offset the expected reduction in energy flow that would otherwise be caused by a warmer topmost few microns according to Fourier's Law.
However the effect of downwelling infrared is always to use up all the infrared in increasing the temperature of the ocean surface molecules whilst leaving nothing in reserve to provide the
extra energy required (the latent heat of
evaporation) when the change of state occurs
from water to vapour.
Of course, if the air were to be warmer than the ocean surface then
evaporation would take the
extra energy required
from the air rather than the water and that 1 mm deep layer (0.3 C cooler than the ocean bulk) would rise to the surface and dissipate but that doesn't happen often or for long.
The
extra evaporation from the DLR would be self limiing in that if it is used to cover part of the deficit then the amount of
evaporation would decrease so only the background deficit needs to be covered.
Extra energy
from DLR can't increase radiation or
evaporation until temperature has risen.
If the energy source that adds energy to the water can not get past the evaporative region (such as DLR) then ALL of it is used up creating
extra evaporation leaving no surplus and failing to reduce the upward energy flow
from the bulk ocean.
Extra DLR
from GHGs could: a) increase the temperature of the skin layer - causing more
evaporation and radiation
from the skin layer OR b) reduce the amount of energy flowing into the skin layer
from below.
It is sufficient for the retention of
extra energy to be
from ocean skin upwards and the process of
evaporation ensures just that.
Thus direct solar heating of the air will cause increased
evaporation as will warming of the water surface by increased downwelling infra red radiation onto the water surface
from, say,
extra human CO2.
Warmer water surfaces
from extra downwelling infra red can not cause warming of the ocean bulk because the rate of
evaporation increases proportionately to the
extra energy available and the latent heat of
evaporation is then taken mostly
from the water.It is then no longer available to warm the ocean bulk.
As regards a warming of the ocean skin,
evaporation is a continuous process caused by temperaure, density and pressure (not just temperature) differentials between water and air so that the rate of
evaporation accelerates when a water surface is warmed such as
from the warming effect of
extra greenhouse gases (especially if the air is dry).
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).
