Whatever the mechanism, it has to be quite fast to
transfer sea temperature properties to air over land so rapidly.
Not exact matches
And because clouds reflect sunlight, cloud dissipation causes more sunlight to
transfer to the ground and
seas, ultimately resulting in warmer ground and air
temperatures.
Hansen mentioned faster
sea level rise as a possibility based on the idea that as the
temperature rises, the rate of heat
transfer to ice rises.
The surface
temperature responds to energy
transfer between the oceans and atmosphere which varies dynamically as a result of changes in
sea surface
temperature.
The
temperature effects were in one sense not all that mysterious — energy
transfer to and from the ocean in shifting regimes of
sea temperature.
This means that if the surface
temperature is constant and energy is slowly
transferring into the water column all the way to the
sea floor, the ocean will keep expanding and
sea level will continue rising.
As evident in the figures the near surface air
temperatures are actually warmer over the Arctic Ocean (by over 1 °C in large areas) when the
sea ice absorbs solar radiation and
transfers some of this energy as sensible heat back into the atmosphere.
Since the rate of energy
transfer is proportional to ∆ T, the air -
sea temperature difference, this changes the total heat going into the atmosphere.
Combining land surface
temperatures and
sea surface
temperatures is a particularly meaningless metric, because SSTs measure the rate at which heat is
transferred from the oceans to the atmosphere.
The
transfer of sensible heat and evaporation fluxes are particularly critical because they feed back on the atmospheric circulation, clouds,
sea ice,
temperature, and humidity.
In a new paper, researchers conclude that changes in sensible heat
transfer and evaporation fluxes — in response to strong regional trends in the air - surface
temperature contrast related to the changing character of the
sea ice cover — are becoming increasingly consequential to Arctic climate variability and change.
Ron, «By using night marine air
temperatures to normalize all
sea data Huang effectively
transferred the tas tend to tos for ERSSTv4» No, it doesn't have that effect.
The sun, currents and energy
transfer processes affect the global pattern of
sea surface
temperatures.
As many climate scientists note in their papers, the relevant
sea surface
temperature for heat
transfer between ocean and atmosphere is the very surface, the skin
temperature.
By using night marine air
temperatures to normalize all
sea data Huang effectively
transferred the tas tend to tos for ERSSTv4 (NOAA's ocean temp index used by GISTEMP).
Spray droplets are cooled to their wet bulb
temperature by evaporation before falling back into the
sea, thereby
transferring a huge amount of heat from
sea to air.
If the net increase in
sea surface
temperature produces a net increase in the rainfall, that entails a net increase in the rate of non-radiative
transfer of energy from the surface to the upper troposphere.
I was only thinking in terms of the heat
transfer and
temperature changes, and have not thought through the implications for
sea level rise.
Variations in SST due to variations in heat transport by ocean currents or diffusion into the thermocline are neglected while contributions by changes in evaporation, turbulent
transfer, and surface radiation are estimated as being proportional to the anomalous air -
sea temperature difference.
