Investigating Cloud Radiative Forcing in the Tropical West Pacific Using a Single-Column Model
نویسنده
چکیده
The Tropical Western Pacific (TWP) is an important region for world climate (Webster and Lucas 1992) and was the subject of the Tropical Ocean Global Atmosphere-Coupled Ocean Atmosphere Response Experiment (TOGA-COARE) in 1992/3. This experiment included an intensive observational period (IOP) from November 1992 through March 1993, which provided observations suitable for creating datasets that can be used for forcing either single-column models (SCMs) or cloud-resolving models (CRMs).

Influence of Dynamics on the Changes in Tropical Cloud Radiative Forcing
Satellite measurements of the radiation budget and data from the U.S. National Centers for Environmental Prediction–National Center for Atmospheric Research reanalysis are used to investigate the links between anomalous cloud radiative forcing over the tropical west Pacific warm pool and the tropical dynamics and sea surface temperature (SST) distribution during 1998. The ratio, N, of the short...
متن کاملEnsemble single column model validation in the tropical western Pacific
[1] Single column models (SCMs) are useful tools for the evaluation of parameterizations of radiative and moist processes used in general circulation models (GCMs). SCM applications have usually been limited to regions where high-quality observations are available to derive the necessary boundary condition or forcing data. Recently, researchers have developed techniques for deriving SCM forcing...

[1] Single column models (SCMs) are useful tools for the evaluation of parameterisations of radiative and moist processes used in general circulation models (GCMs). Most SCM studies to date have concentrated on regions where there is a sufficiently dense observational network to derive the required forcing data. This paper describes an ensemble single column modeling (ESCM) approach where the f...
متن کاملDynamic Effects on the Tropical Cloud Radiative Forcing and Radiation Budget
Vertical velocity is used to isolate the effect of large-scale dynamics on the observed radiation budget and cloud properties in the tropics, using the methodology suggested by Bony et al. Cloud and radiation budget quantities in the tropics show well-defined responses to the large-scale vertical motion at 500 hPa. For the tropics as a whole, the ratio of shortwave to longwave cloud forcing (he...
متن کاملOn the Fundamental Role of Day Versus Night Radiation Differences in Forcing Nocturnal Convective Maxima and in Assessing Global Warming Prospects
An analyses of Geostationary Meterological Satellite (GMS) data for the tropical West Pacific yields new perspectives on clear/cloud area radiative forcing of enhanced nocturnal convection. Consideration of the tendency for two-to-three-day cycles of intense broadscale convection becomes an important factor in assessing the actual amplitude of clear/cloudy area diurnal forcing. Recurrent system...
