January and July Global Distributions of Atmospheric Heating for 1986, 1987, and 1988
Publisher: American Meteorological Society
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 ...
Seasonal Distributions of Mountain Torques during FGGE
Publisher: American Meteorological Society
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 ...
Global Heating Distributions for January 1979 Calculated from GLA Assimilated and Simulated Model-based Datasets
Publisher: American Meteorological Society
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 ...
Stratospheric–Tropospheric Mass Exchange during the Presidents' Day Storm
Publisher: American Meteorological Society
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 ...
A Global Analysis of Stratospheric–Tropospheric Exchange during Northern Winter
Publisher: American Meteorological Society
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 ...
Heating Distributions from January and July Simulations of NCAR Community Climate Models
Publisher: American Meteorological Society
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 ...
Global Objective Tropopause Analysis
Publisher: American Meteorological Society
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 ...
Global Climate Simulation with the University of Wisconsin Global Hybrid Isentropic Coordinate Model
Publisher: American Meteorological Society
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 ...
A Comparison of Inert Trace Constituent Transport between the University of Wisconsin Isentropic–Sigma Model and the NCAR Community Climate Model
Publisher: American Meteorological Society
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 ...
Numerical Uncertainties in Simulation of Reversible Isentropic Processes and Entropy Conservation: Part II
Publisher: American Meteorological Society
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 ...
