Sentences with phrase «upward flux»
The phrase "upward flux" means the movement or flow of something going upward or rising. Full definition
On this particular point, one said:» The overall concluding statement that «the existence of a stable climate requires a unique surface upward flux density and a unique optical depth of 1.841» makes absolutely no sense at all.

Modtran indicates that maintaining constant clear sky upward flux after a doubling of CO2 (70 KM altitude, looking down, constant relative humidity) requires ~ 1.9 C higher surface temperature in the tropics but a bit less than 1C in the subarctic.
If it reverses, we can treat the value at the point of reversal (marking a maximum height or depth of the hill or valley in the net upward flux spectrum) as the saturation value, and then include some additional effect at the center of the band for additional increases in CO2 that have the opposite sign as the band widenning in their contributions to radiative forcing.
This shows upward fluxes through the top of the pycnocline of about 1 watt in the Beayfort Sea, and 2 - 3 watts over the Chukchi Shelf, an area influenced by the Pacific inflow.
Enhanced snow cover over Eurasia during October stimulates the development and westward expansion of the Siberian high, which subsequently produces anomalous upward fluxes of wave energy into the stratosphere that lead to warming and a weakening of the polar vortex.
The increase in downward flux, F ↓, is matched by the decrease in upward flux, F ↑.
Patrick (348)-- I wonder whether you're using the terms «upward flux» and «net upward flux» interchangeably.
But then there's feedbacks within the stratosphere (water vapor), which would increase the stratospheric heating by upward radiation from below, as well as add some feedback to the downward flux at TRPP that the upward flux at TRPP would have to respond to via warming below TRPP.
CO2 puts a valley in the upward flux; at the tropopause it puts a hill in the downward flux, which combine to form a valley in the net upward flux.
That doens» t affect the equilibrium increase in the upward flux at TRPP in response, though it may change how much of that is absorbed by the stratosphere (perhaps a reduction due to shielding of water vapor and CO2 wings in the stratosphere by increased tropospheric water vapor (as it would by an increase in clouds, particularly higher clouds)-- PS feedbacks also change the baseline spectral flux in the vicinity of the CO2 band.
So, assuming the same baseline net upward flux (transparent (except for CO2) stratosphere in the vicinity of the CO2 band), if the CO2 valley in net upward flux is saturated (at the center) at TRPP, the depth of the TRPP valley is deeper than the valley at TOA both before doubling, after doubling, and even at TOA saturation.
