Radiative Heating in Global Climate Models
نویسنده
چکیده
Climate model dynamics are driven by external and internal forcing. The primary forces affecting the thermal field are long wave radiative (LWR) heating, short wave radiative (SWR) heating, and convection (cumulus, etc.). These forcing effects are cycled through the thermal field to the motion field by nonlinear transfer. The model dependent variables, in particular temperature (T), moisture (Q), and especially clouds, evolve in time in a Global Climate Model (GCM) and thereby determine the subsequent forcing. If the dependent variables are not accurately calculated in space and time, the predicted forcing functions will be adversely affected. As integration time proceeds, such inaccuracies will lead to systematic errors in the prediction of climate.

Combining satellite data and models to estimate cloud radiative effect at the surface and in the atmosphere
Satellite measurements and numerical forecast model reanalysis data are used to compute an updated estimate of the cloud radiative effect on the global multi-annual mean radiative energy budget of the atmosphere and surface. The cloud radiative cooling effect through reflection of short wave radiation dominates over the long wave heating effect, resulting in a net cooling of the climate system ...
متن کاملLongwave Radiative Forcing in Global Climate Models
Long wave radiation (LWR) forcing is determined in atmospheric global climate models (AGCMs) by a heating algorithm embedded in the model. These algorithms compute vertical heating rate (HR) profiles from profiles of temperature (T), moisture (Q), clouds, and minor atmospheric constituents; thus the HRs depend on the vertical structure of the input variables plus internal physics. The sensitivi...
متن کاملCloud Radiative Heating Rate Forcing Using Profiles of Retrieved Arctic Cloud Microphysics
Clouds and their radiative impacts are of primary importance to the Arctic climate and, therefore, global climate. Clouds dominate the radiation balance within the cold, dry Arctic atmosphere, and cloudradiation feedbacks are closely linked with the snow/ice-albedo feedback. Despite the importance of clouds in the Arctic, our current understanding of these clouds remains limited. Global climate...
متن کاملA Generalized Energy Balance Climate Model with Parameterized Dynamics and Diabatic Heating
Energy balance models have proven useful in understanding mechanisms and feedbacks in the climate system. An original global energy balance model is presented here. The model is solved numerically for equilibrium climate states defined by zonal average temperature as a function of latitude for both a surface and an atmospheric layer. The effects of radiative, latent, and sensible heating are pa...

Land-use and land-cover changes (LULCC) significantly affect weather and climate as iswell documented in the scientific literature. These impacts include changes in air temperature, precipitation, atmospheric moisture content, energy fluxes, and mesoscale and potentially large-scale circulations. Recently, the United States National Research Council (2005) highlighted the importance of LULCC an...
