On the Use of Mesoscale and Cloud-Scale Models in Operational Forecasting
(American Meteorological Society, 1992)In the near future, the technological capability will be available to use mesoscale and cloud-scale numerical models for forecasting convective weather in operational meteorology. We address some of the issues concerning ... -
The Impact of Satellite-derived Winds on Numerical Hurricane Track Forecasting
(American Meteorological Society, 1992)While qualitative information from meteorological satellites has long been recognized as critical for monitoring tropical cyclone activity, quantitative data are required to improve the objective analysis and numerical ... -
An Upper-Tropospheric Low over Texas during Summer
(American Meteorological Society, 1992)National Meteorological Center 200-mb analyses are used to develop an abridged six-year climatology of the tropical upper-tropospheric trough (TUTT) over the Gulf of Mexico. The climatology reveals large intraseasonal and ... -
Systematic Model Forecast Errors of Surface Cyclones in NMC's Nested-Grid Model, December 1988 through November 1990
(American Meteorological Society, 1992)Systematic errors in the nested-grid model (NGM) forecasts of surface cyclones are examined over a two-year period from 1 December 1988 through 30 November 1990. The parameters examined include the location, central pressure, ... -
The Taku Wind of Southeast Alaska: Its Identification and Prediction
(American Meteorological Society, 1992)The purpose of this study is to investigate the occurrence of severe winds in southeast Alaska (locally known as Taku winds) based on recent theoretical advances in the understanding of severe downslope windstorms. We found ... -
Diagnosing Coupled Jet-Streak Circulations for a Northern Plains Snow Band from the Operational Nested-Grid Model
(American Meteorological Society, 1992)On 17 March 1989, moderate to heavy snow developed in a 100- to 200-km-wide band extending from South Dakota to northern Michigan. The 4- to 8-inch snowfall within this band was not associated with major cyclogenesis, and ... -
Skill of Operational Dynamical Models in Cyclone Prediction Out to Five-Days Range during ERICA
(American Meteorological Society, 1992)Investigating the skill of prediction of surface cyclones by operational models to ranges of five days, we studied the central and western North Atlantic region for the December 1988 through February 1989 period of the ... -

Forecasting Techniques Utilized by the Forecast Branch of the National Meteorological Center During a Major Convective Rainfall Event
(American Meteorological Society, 1991)Meteorologists within the Forecast Branch (FB) of the National Meteorological Center (NMC) produce operational quantitative precipitation forecasts (QPFs). These manual forecasts are prepared utilizing various forecasting ... -
The New Global Operational Analysis System at the National Meteorological Center
(American Meteorological Society, 1991)At the National Meteorological Center (NMC), a new analysis system was implemented into the operational Global Data Assimilation System on 25 June 1991. This analysis system is referred to as Spectral Statistical Interpolation ... -
The Agnes Rainstorm of June 1972: Surface Feature Evolution Culminating in Inland Storm Redevelopment
(American Meteorological Society, 1991)The passage of Tropical Storm Agnes through the eastern United States on 21?23 June 1972 was marked by a swath of exceptionally heavy rainfall amounting to 15?35 cm. The heaviest rains fell in a narrow band from eastern ... -
Characteristics of East-Central Florida Tornado Environments
(American Meteorological Society, 1991)Climatological analyses indicate that strong morning tornadoes in the dry season, and weak afternoon tornadoes in the wet season, are significant forecast problems in east-central Florida. To address this issue, an analysis ... -
Further Evaluation of the National Meterological Center's Medium-Range Forecast Model Precpitation Forecasts
(American Meteorological Society, 1991)Precipitation forecasts made by the National Meteorological Center's medium-range forecast (MRF) model are evaluated for the period, 1 March 1987 to 31 March 1989. As shown by Roads and Maisel, the MRF model wet bias was ... -
Wet Microburst Activity over the Southeastern United States: Implications for Forecasting
(American Meteorological Society, 1991)The thermodynamic properties of wet-microburst-producing days, as observed during the 1986 MIST (MIcroburst and Severe Thunderstorm) field project, conducted in northern Alabama, have been examined and are shown to exhibit ...
