Comments on “A Winter Mesocyclone over the Midwestern United States”
(American Meteorological Society, 1990)No abstract available -
Reduction of Tropical Cyclone Position Errors Using an Optimal Combination of Independent Forecasts
(American Meteorological Society, 1990)It is shown that an optimal linear combination of independent forecasts of tropical cyclone tracks significantly reduces the mean forecast-position errors. In this study the independent forecasts are provided by a statistical ... -
Meteorological Causes of the 1881 Fire in Michigan's Thumb Area
(American Meteorological Society, 1990)During the lumbering era of the late 1800s, a number of forest firm blazed across the upper Midwest. The climatological conditions in the months before these disasters have already been presented in other studies. This ... -
Delimiting “Thunderstorm Watch” Periods by Real-Time Lightning Location for a Power Utility Company
(American Meteorological Society, 1990)During times of thunderstorm activity, the power utility serving metropolitan New York enters a potentially costly ?thunderstorm watch? mode of operation which is designed to prevent a major power outage caused by lightning. ... -
New NGM-Based MOS Guidance for Maximum/Minimum Temperature, Probability of Precipitation, Cloud Amount, and Surface Wind
(American Meteorological Society, 1990)In this paper, we describe the development and use of new nested grid model (NGM)-based model output statistics (MOS) guidance that has been available since 26 July 1989 for 204 stations in the contiguous United States. ... -
A Statistical Comparison of the Forecasts Produced by the NGM and LFM for the 1987/88 Cool Season
(American Meteorological Society, 1990)Forecasts from the National Meteorological Center's (NMC) nested grid model (NGM) and limited-area fine-mesh model (LFM) were compared objectively for the 1987/88 cool season. Mean values of various predicted variables ... -
The Role of Mesoscale Features in a Wintertime Great Lakes Cyclone
(American Meteorological Society, 1990)An analysis documenting the role of synoptic and surface mesoscale features in a cyclone has been conducted to determine the physical processes responsible for a large snowfall observed over south-central Wisconsin on 25 ... -
Wind Profiler Observations Preceding Outbreaks of Large Hail over Northeastern Colorado
(American Meteorological Society, 1990)Wind profiler, rawinsonde, and surface observations of the atmosphere over northeastern Colorado during the morning hours on 44 days were compared to the severity of subsequent thunderstorm activity. On half of thes days, ... -
Prediction of Vessel Icing for Near-Freezing Sea Temperatures
(American Meteorological Society, 1990)The operational NOAA categorical vessel icing algorithm is evaluated with regard to advances in understanding of the icing process and forecasting experience. When sea temperatures are <2?3°C above the saltwater freezing ... -
An Error Analysis of Atlantic Tropical Cyclone Track Guidance Models
(American Meteorological Society, 1990)Mean track forecast errors over the 6-yr period 1983?88 are compared for four tropical cyclone-track forecast models in use at the National Hurricane Center (NHC). The model types represented are statistical, statistical ... -
Prefrontal Troughs over Southern Australia. Part II: A Case Study of Frontogenesis
(American Meteorological Society, 1990)A case study of frontogenesis within a surface prefrontal trough over southern Australia is presented. The trough developed ahead of a surface cold front and, over a period of approximately 24 h, intensified into a mature ... -
Prefrontal Troughs over Southern Australia. Part I: A Climatology
(American Meteorological Society, 1990)A climatology of the prefrontal westerly trough of southern Australia is presented, based on data for the 10-yr period 1976?85. Trough formation was confined to the longitudes of the Australian continent in the warmer ... -
The Minneapolis Flash Flood: Meteorological Analysis and Operational Response
(American Meteorological Society, 1990)The evolution of the synoptic- and meso-α-scale meteorological setting for the 23 July 1987 Minneapolis flash flood is described. Analyses of conventional upper-air data, including quasi-geostrophic processes, are employed ... -
The Formative Rossby-Reichelderfer Period in American Meteorology, 1926–40
(American Meteorological Society, 1989)By working together between 1926 and 1940, two young meteorologists, Carl-Gustav A. Rossby and Francis W. Reichelderfer, played catalytic roles in the following facets of American meteorology: 1) starting a model airway ... -
The Evolution of Severe Thunderstorm Criteria within the Weather Service
(American Meteorological Society, 1989)The evolution of criteria for nontornadic severe thunderstorms from undefined categories and general terms to the present day definition for this class of thunderstorm is presented. Major historical events in the development ... -

Systematic Surface Anticyclone Errors in Nested Grid Model Run at NMC: December 1988–August 1989
(American Meteorological Society, 1989)A quantitative assessment has been made of the surface anticyclone forecast errors found in the operational nested grid model (NGM) run at the National Meteorological Center (NMC). Preliminary results covering a period ...
