More radiation out = lower temps and
less radiation out = higher temps.
Not exact matches
Bekelman points
out that fewer
radiation treatments not only means
less out - of - pocket costs and fewer visits to treatment centers for patients; it also means lower costs for payers and employers.
The sun puts
out less energy when its activity is low, but different types of
radiation vary to different degrees.
The particles could have acted like a shield, blocking
out the sun and preventing some
radiation from evaporating water on the planet's surface, resulting in even
less rainfall.
CO2 (and some other gases) in the atmosphere are however more opaque to LWIR; they absorb that a chunk of that outgoing
radiation and re-radiate it in all directions — so that a fraction
less than half is re-radiated downwards; which has the effect of slowing the transfer of heat (by
radiation)
out of the atmosphere.
What I meant was that Planck
radiation increases with body or amb ient temperature, but higher temperature, per the Boltzmann distribution, makes it more probable that rotation, vibration, and / or electronic levels will be excited, and therefore
less likely to emit relaxation energy, though as you point
out this may not be exactly what happens physically — emission
radiation is more flat than anything with increasing temperatures.
The back -
radiation explanation of the greenhouse effect that people used to prefer until recently is
less satisfactory because it has the kinds of problems I pointed
out 16 months ago in an article on this blog, which was received at the time with only slightly more enthusiasm than Galileo's heliocentric account of planetary motions: at least no one suggested I be placed under house arrest for it!
Cooler glazing temperatures would indicate that collector heated air is not working its way
out to the glazing and warming it, and / or that the glazing was seeing
less radiation heating from the absorber screens.
As one goes further north toward the North Pole, the length of the shortwave
radiation season is shortened with
less ability to melt
out multi-year sea ice (D. Perovich, personal communication).
If
less energy comes in, the governor will try to maintain the energy flux into the system (Willis's retarding the appearance of clouds) but once all stops have been pulled
out (the sky is clear morning to night), then the engine slows down — slower air and water currents,
less addition of heat to the polar areas, dissipation of what heat has accumulated by
radiation into space and return cold water not getting the heating it formerly did.
Nov 2007) and the comment of Meier et al. (below) point
out that at far northern latitudes, the surface receives
less solar
radiation over the summer season compared with the Beaufort Sea.
Today Earth is
out of balance because increasing atmospheric gases such as CO2 reduce Earth's heat
radiation to space, thus causing an energy imbalance, as there is
less energy going
out than coming in.
For this reason, the shell will receive
less W / sqm from Earth
radiation than is emitted by the surface, because the
radiation will spread
out by the inverse square law just as sunlight gets
less intense the further from the sun you get, and the shell will radiate more to space than back to Earth.
In the real world, increased concentrations of CO2 would theoretically block a certain proportion of incoming solar insolation so that
less solar radiance is absorbed by the ground and oceans, and it would also increase the rate of
out going
radiation at TOA.
