Abstract: Three-dimensional global distributions of atmospheric heating are estimated for January and July of the 3-year period 1986?88 from the ECMWF/TOGA assimilated datasets. Emphasis is placed on the interseasonal and interannual ...

Abstract: Based on surface pressure and terrain height analyses from the National Meteorological Center, mountain torques are calculated for January, April, July and October 1979 during the First GARP Global Experiment. The zonally ...

Abstract: Global distributions of atmospheric heating for January 1979 are estimated from two Global Weather Experiment (GWE) Level III datasets generated at the Goddard Laboratory for Atmospheres (GLA). One set utilized data from ...

Abstract: Using data generated from a model simulation, the exchange of mass between the stratosphere and the troposphere is estimated for the Presidents' Day storm during a 24-h period beginning at 1500 UTC 18 February 1979. This ...

Abstract: Using a mathematical formulation of stratospheric-tropospheric (ST) exchange, the cross-tropopause mass flux is diagnosed globally for January 1979. Contributions by physical mechanisms including the diabatic transport and ...

Abstract: Simulations of the global distribution of heating (the sum of latent, sensible, short and longwave radiation) are presented for January and July using the R15 NCAR Community Climate Model (CCM). The vertical and horizontal ...

Abstract: The European Center for Medium Range Weather Forecasts (ECMWF) level IIIb dataset is used to construct global pressure analyses of the tropopause surface during January 1979. Two methods are employed: a dynamical method ...

Abstract: The purpose of this study is to briefly describe the global atmospheric University of Wisconsin (UW) hybrid isentropic?eta coordinate (UW ???) model and document results from a 14-yr climate simulation. The model, developed ...

Abstract: Five- and 10-day inert trace constituent distributions prognostically simulated with the University of Wisconsin (UW) hybrid isentropic?sigma (??σ) model, the nominally identical UW sigma (σ) model, and the National Center ...

Abstract: The objectives of this study are 1) to provide the framework for an in-depth statistical analysis of the numerical uncertainties in the simulation of conservation of entropy, potential vorticity, and like properties under ...
