RISA Global Version of the PSU–NCAR Mesoscale Model
Publisher: American Meteorological Society
Abstract: A global version of the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (PSU?NCAR MM5) is described. The new model employs two polar stereographic projection domains ...
Case Study of an Unusual Long-Range Sulfur Transport Episode
Publisher: American Meteorological Society
Abstract: Observations of extremely high fine particulate sulfur concentrations during early April 1983 in the western United States are linked to a strong cyclone over the midwestern United States. The strong winds around this ...
An Intense Small-Scale Wintertime Vortex in the Midwest United States
Publisher: American Meteorological Society
Abstract: An intense small-scale low pressure system that moved across portions of the midwest United States is examined. The system produced a continuous band of significant snowfall, typically only 50 km wide but extending over ...
Comparison of Impacts of WRF Dynamic Core, Physics Package, and Initial Conditions on Warm Season Rainfall Forecasts
Publisher: American Meteorological Society
Abstract: A series of simulations for 15 events occurring during August 2002 were performed using the Weather Research and Forecasting (WRF) model over a domain encompassing most of the central United States to compare the sensitivity ...
Diagnosed Characteristics of Precipitation Systems over Taiwan during the May–June 1987 TAMEX
Publisher: American Meteorological Society
Abstract: Characteristics of Mei-Yu precipitating cloud systems over Taiwan during the May?June 1987 Taiwan Area Mesoscale Experiment (TAMEX) have been studied using sounding, surface precipitation, and radar data. Vertical motion ...
A Polar-Low Development over the Bering Sea: Analysis, Numerical Simulation, and Sensitivity Experiments
Publisher: American Meteorological Society
Abstract: A polar low that developed over the western Bering Sea on 7 March 1977 and tracked across St. Paul Island is investigated using observations and the Pennsylvania State University?National Center for Atmospheric Research ...
Vertical Interpolation of Meterological Variables
Publisher: American Meteorological Society
Abstract: The initialization of numerical prediction models usually requires the transformation of variables observed in a p-coordinate system into some other coordinate frame of reference (e.g., α-coordinates or Θ-coordinates). ...
Some Aspects of the Effects of Sensible Heating on the Development of Summer Weather Systems over the Tibetan Plateau
Publisher: American Meteorological Society
Abstract: The influence of sensible heating from the earth's surface on the development of summertime vortices over the Tibetan Plateau was investigated using a numerical model. It was found that sensible heating could cause local ...
The Stratosphere–Troposphere Analyses of Regional Transport 2008 Experiment
Publisher: American Meteorological Society
Abstract: The Stratosphere?Troposphere Analyses of Regional Transport 2008 (START08) experiment investigated a number of important processes in the extratropical upper troposphere and lower stratosphere (UTLS) using the National ...
The O2/N2 Ratio and CO2 Airborne Southern Ocean Study
Publisher: American Meteorological Society
Abstract: AbstractThe Southern Ocean plays a critical role in the global climate system by mediating atmosphere?ocean partitioning of heat and carbon dioxide. However, Earth system models are demonstrably deficient in the Southern ...
