Longwave Radiative Forcing in Global Climate Models
نویسندگان
چکیده
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 sensitivity of various algorithms (taken from AGCMs) to these input variables was tested; examples of their sensitivity can be found in Baer et al. (1996). It is particularly noteworthy that the algorithms are extremely sensitive to clouds.

Cloud-radiative forcing and climate: results from the Earth radiation budget experiment.
The study of climate and climate change is hindered by a lack of information on the effect of clouds on the radiation balance of the earth, referred to as the cloud-radiative forcing. Quantitative estimates of the global distributions of cloud-radiative forcing have been obtained from the spaceborne Earth Radiation Budget Experiment (ERBE) launched in 1984. For the April 1985 period, the global...
متن کاملEarth ’ s Annual Global Mean Energy Budget J . T . Kiehl and Kevin
The purpose of this paper is to put forward a new estimate, in the context of previous assessments, of the annual global mean energy budget. A description is provided of the source of each component to this budget. The top-ofatmosphere shortwave and longwave flux of energy is constrained by satellite observations. Partitioning of the radiative energy throughout the atmosphere is achieved throug...
متن کاملRadiative forcing by long-lived greenhouse gases: Calculations with the AER radiative transfer models
[1] A primary component of the observed recent climate change is the radiative forcing from increased concentrations of long-lived greenhouse gases (LLGHGs). Effective simulation of anthropogenic climate change by general circulation models (GCMs) is strongly dependent on the accurate representation of radiative processes associated with water vapor, ozone, and LLGHGs. In the context of the inc...
متن کاملA Study of Longwave Radiation Codes for Climate Studies: Validation with Observations and Tests in General Circulation Models-an Update
Introduction to compare calculations from a set of models with operationally observed data. The differences we find will lead to the development of new models to be tested with new data. Similarly. our GCM studies will use existing GCMs to study the radiation sensitivity problem. We anticipate that the outcome of this approach will provide both a better longwave radiative forcing algorithm and ...
متن کاملUsing the Radiative Kernel Technique to Calculate Climate Feedbacks in NCAR’s Community Atmospheric Model
Climate models differ in their responses to imposed forcings, such as increased greenhouse gas concentrations, due to different climate feedback strengths. Feedbacks in NCAR’s Community Atmospheric Model (CAM) are separated into two components: the change in climate components in response to an imposed forcing and the “radiative kernel,” the effect that climate changes have on the top-of-theatm...
متن کاملDirect radiative effect of mineral dust and volcanic aerosols in a simple aerosol climate model
[1] Airborne mineral dust can influence the climate by altering the radiative properties of the atmosphere, but the magnitude of the effect is uncertain. An idealized global model is developed to study the dust-climate system. The model determines the dust longwave and shortwave direct radiative forcing, as well as the resulting temperature changes, based on the specified dust distribution, hei...
