Sentences with phrase «radiative equilibrium level»

Not exact matches

To say it a bit worse but in modern lingo: to maintain radiative equilibrium, the planet has to put out a certain amount of heat, and if it can't radiate it out from the surface, the lower atmosphere somehow has to get warmer until there's some level that radiates the right amount.

In full equilibrium, at any given level, there may be some net radiative heating at some frequencies compensated by some net radiative cooling at other frequencies, with convection balancing the full spectrum radiative cooling of the troposphere and heating of the surface.

The stratosphere will, absent sustained non-radiative perturbations (see 57i), approach radiative equilibrium on a time scale under a year (Holton, «An Introduction to Dynamic Meteorology», 1992, p. 410), so taking stratospheric adjustment to instantaneous stratospheric forcing first and then applying the adjusted tropopause - level forcing to the troposphere + surface and stratospheric feedbacks is similar to the actual order of events in reality.

But that level very likely will be less than that based on the extremely over-simplified, zeroth - order radiative - equilibrium so - called model.

ECS is the increase in the global annual mean surface temperature caused by an instantaneous doubling of the atmospheric concentration of CO2 relative to the pre-industrial level after the model relaxes to radiative equilibrium, while the TCR is the temperature increase averaged over 20 years centered on the time of doubling at a 1 % per year compounded increase.

Re 416 Bernd Herd — in climate science, for global climate change, specifically a global (average surface) temperature change in response to a global (typically average net tropopause - level after stratospheric adjustment) radiative forcing (or other heat source — although on Earth those tend not to be so big), where the radiative forcing may be in units of W / m ^ 2, so that equilibrium climate sensitivity is in K * m ^ 2 / W (it is often expressed as K / doubling CO2 as doubling CO2 has a certain amount of radiative forcing for given conditions).
