RISGlobal 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 ...
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 ...
Analysis of the Impact of Seasat Scatterometer Data and Horizontal Resolution on GLA Model Simulations of the QE II Storm
Publisher: American Meteorological Society
Abstract: Quasi-Lagrangian diagnostics of mass, angular momentum, water vapor, and kinetic energy are evaluated for four different Goddard Laboratory for Atmospheres model simulations of the Queen Elizabeth II storm of 9?11 September ...
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 ...
Assessing the Accuracy of the Cloud and Water Vapor Fields in the Hurricane WRF (HWRF) Model Using Satellite Infrared Brightness Temperatures
Publisher: American Meteorological Society
Abstract: n this study, cycled forecast experiments were performed to assess the ability of different cloud microphysics and cumulus parameterization schemes in the Hurricane Weather Research and Forecasting (HWRF) Model to accurately ...
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 ...
Numerical Uncertainties in the Simulation of Reversible Isentropic Processes and Entropy Conservation
Publisher: American Meteorological Society
Abstract: A challenge common to weather, climate, and seasonal numerical prediction is the need to simulate accurately reversible isentropic processes in combination with appropriate determination of sources/sinks of energy and ...
