Abstract: The performance of the nested grid model (NGM) in predicting heavy rain is assessed for those cases in the cool season when moderato-to-strong low-level southerly inflow from the Gulf of Mexico is present. This study ...

Abstract: The National Meteorological Center (NMC) initiated Quantitative Precipitation Forecasts (QPF) and an intensive QPF verification program in 1960. These forecast products have evolved from a manual effort, relying on extensive ...

Abstract: This paper details the performance characteristics of the two regional dynamical models used at the National Meteorological Center to forecast for North America. Strengths and weaknesses of these models?the limited-area ...

Abstract: A synoptic?dynamic climatology was constructed using all 24-h 2-in. (50.8 mm) or greater rainfall events in nine states affected by heavy rains and flooding from June through September 1993 using 6- or 12-h gridded analyses ...

Abstract: This paper assesses the performance of the National Meteorological Center (NMC) Nested-Grid Model (NGM) during a period from March 1988 through March 1990, and the NMC medium-range forecast model (MRF) in two 136-day tests, ...

Abstract: Extreme rainfall events contribute a large portion of wintertime precipitation to northern California. The motivations of this paper were to study the observed differences in the patterns between extreme and more commonly ...

Abstract: This note describes changes that have been made to the National Centers for Environmental Prediction (NCEP) operational ?early? eta model. The changes are 1) an decrease in horizontal grid spacing from 80 to 48 km, 2) ...
