Sentences with phrase «radiative feedback»

The cloud feedback remains the most uncertain radiative feedback in climate models.

It's not quantitative for several reasons (ocean heat uptake, the dependence of radiative feedbacks on the spatial structure of the SST changes, etc).

Acting as a safety valve of sorts, this response creates a negative radiative feedback that allows more of the accumulating heat to be released into space through the top of the atmosphere.

The net radiative feedback due to all cloud types is likely (> 66 % chance) positive, although a negative feedback (damping global climate changes) is still possible.

This was revealed through a key aspect of the simulation called radiative feedback, which accounted for the way X-rays emitted by the black hole affected distant gas.

There are many radiative feedbacks: some positive, some negative.

Continuous measurements was used for the first time to estimate the direct radiative feedback of natural aerosols

The large spread in cloud radiative feedbacks leads to the conclusion that differences in cloud response are the primary source of inter-model differences in climate sensitivity (see discussion in Section 8.6.3.2.2).

Allan, R.P., V. Ramaswamy, and A. Slingo, 2002: A diagnostic analysis of atmospheric moisture and clear - sky radiative feedback in the Hadley Centre and Geophysical Fluid Dynamics Laboratory (GFDL) climate models.

Jerome Fast has lead a team of PNNL scientists that have contributed a gas - phase chemistry mechanism, an sectional aerosol model, cloud chemistry, cloud - aerosol interactions, and radiative feedback processes into the chemistry version of Weather Research and Forecasting (WRF - chem) model.

The 1D diffusion equation model described in Rose et al. (2014) GRL, with spatially varying radiative feedback and diffusion of moist static energy.

Part of this sensitivity is attributed to a physically realistic positive radiative feedback, whereby a propensity toward higher cloud fractions in any given simulation is amplified by longwave radiative cooling.

Their analysis shows that radiative heating is roughly 20 % of convective heating, right around the predicted critical threshold for a convective - radiative feedback loop.

The diagnosis of global radiative feedbacks allows better understanding of the spread of equilibrium climate sensitivity estimates among current GCMs.

Radiative feedbacks act the same way as radiative forcings, except that they themselves are dependent on temperature changes (the distinction depends on timescale and context; also, in some contexts the feedbacks» effects are described as radiative forcings — for example, the radiative forcing of the increase in water vapor that would occur for a given temperature increase).

Continuous measurements was used for the first time to estimate the direct radiative feedback of natural aerosols

Radiative feedback from liquid water in the atmosphere far exceeds anything CO2 can do.

The biggest conclusion, as one report stated, was that «cloud radiative feedback is the single most important effect determining the magnitude of possible climatic responses to human activity.»

After more thorough analysis I found a problem in which there was too much ice in the upper troposphere, which really messed up the radiative feedbacks.

It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.
