Diurnal Variability of the Hydrologic Cycle in a General Circulation Model
Publisher: American Meteorological Society
Abstract: This paper presents an analysis of the diurnal and semidiurnal variability of precipitation, evaporation, precipitable water, horizontal moisture flux convergence, cloudiness, and cloud radiative forcing, as simulated by ...
Relationship between the Longwave Cloud Radiative Forcing at the Surface and the Top of the Atmosphere
Publisher: American Meteorological Society
Abstract: Attempts to map the global longwave surface radiation budget from space have been thwarted by the presence of clouds. Unlike the shortwave, there is no physical relationship between the outgoing longwave and the surface ...
Interactions among Radiation, Convection, and Large-Scale Dynamics in a General Circulation Model
Publisher: American Meteorological Society
Abstract: We have analyzed the effects of radiatively active clouds on the climate simulated by the UCLA/GLA GCM, with particular attention to the effects of the upper tropospheric stratiform clouds associated with deep cumulus ...
The Ill-posed Nature of the Satellite Temperature Retrieval Problem and the Limits of Retrievability
Publisher: American Meteorological Society
Abstract: The inverse problem of satellite temperature profile retrieval is well known to be ill-posed. Ibis means that not only is a vertical temperature profile solution not unique, but that two solutions can be very different ...
Pattern Recognition in the Satellite Temperature Retrieval Problem
Publisher: American Meteorological Society
Abstract: Two Pattern recognition procedures are developed to provide improvements to first-guess fields for satellite temperature retrievals. The first is a technique whereby a radiometer measurement may be used to select one or ...
Impact of Evapotranspiration on Dry Season Climate in the Amazon Forest
Publisher: American Meteorological Society
Abstract: oisture recycling can be an important source of rainfall over the Amazon forest, but this process relies heavily upon the ability of plants to access soil moisture. Evapotranspiration (ET) in the Amazon is often maintained ...
A Revised Land Surface Parameterization (SiB2) for Atmospheric GCMS. Part II: The Generation of Global Fields of Terrestrial Biophysical Parameters from Satellite Data
Publisher: American Meteorological Society
Abstract: The global parameter fields used in the revised Simple Biosphere Model (SiB2) of Sellers et al. are reviewed. The most important innovation over the earlier SiB1 parameter set of Dorman and Sellers is the use of satellite ...
