RISInitial Results from a Mesoscale Atmospheric Simulation System and Comparisons with the AVE-SESAME I Data Set
Publisher: American Meteorological Society
Abstract: The development of a comprehensive mesoscale atmospheric simulation system (MASS) is described in detail. The modeling system is designed for both research and real-time forecast applications. The 14-level numerical model, ...
Synergistic Interactions between an Upper-Level Jet Streak and Diabatic Processes that Influence the Development of a Low-Level Jet and a Secondary Coastal Cyclone
Publisher: American Meteorological Society
Abstract: A series of numerical simulations is presented for the February 1979 Presidents' Day cyclone in order to understand more fully the roles played by upper-level jet streaks the oceanic planetary boundary layer (PBL), and ...
A VAS-Numerical Model Impact Study Using the Gal-Chen Variational Approach
Publisher: American Meteorological Society
Abstract: Numerical experiments are conducted to assess the impact of incorporating temperature data from the VISSR Atmospheric Sounder (VAS) into a regional-scale numerical model using an assimilation technique developed by Gal-Chen. ...
The Regional Analysis and Forecast System of the National Meteorological Center
Publisher: American Meteorological Society
Abstract: The three components of the Regional Analysis and Forecast System (RAFS) of the National Meteorological Center (NMC) are described. This system was implemented in March 1985 to supplement guidance from NMC's limited-area ...
Changes to NMC's Regional Analysis and Forecast System
Publisher: American Meteorological Society
Abstract: The recent implementation of changes to the National Meteorological Center's (NMC's) Regional Analysis and Forecast System (RAFS) is described. The changes include an expansion of the innermost grids of the nested-grid ...
