A Synoptic Investigation of Anticyclogenesis Accompanying North American Polar Air Outbreaks
Publisher: American Meteorological Society
Abstract: Results are presented for a synoptic-dynamic investigation of certain polar anticyclones originating in northwestern Canada.. A composite, consisting of three similar high pressure systems, is constructed. This cold ...
Automated Temperature Guidance Based on Three-Month Seasons
Publisher: American Meteorological Society
Abstract: For the last few years the National Weather Service has been producing centralized guidance forecasts of calendar day maximum and minimum temperatures by applying multiple regression equations derived statistically from ...
Statistical Forecasts Based on the National Meteorological Center's Numerical Weather Prediction System
Publisher: American Meteorological Society
Abstract: The production of interpretive weather element forecasts from dynamical model output variables is now an integral part of the centralized guidance systems of weather services throughout the world. The statistical forecasting ...
Improved Automated Surface Temperature Guidance
Publisher: American Meteorological Society
Abstract: Currently, two sets of automated numerical-statistical forecasts of maximum/minimum (max/min) temperatures for calendar day periods are produced in the day-to-day operations of the National Weather Service. The ?early? ...
New NGM-Based MOS Guidance for Maximum/Minimum Temperature, Probability of Precipitation, Cloud Amount, and Surface Wind
Publisher: American Meteorological Society
Abstract: 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. ...
Evaluating the Impact of RAFS Changes on the NGM-Based MOS Guidance
Publisher: American Meteorological Society
Abstract: In the spring of 1990, the National Meteorological Center (NMC) tested several modifications to the Regional Analysis and Forecast System (RAFS). In order to compare the proposed version of the RAFS to the current operational ...
Trends in Comparative Verification Scores for Guidance and Local Aviation/Public Weather Forecasts
Publisher: American Meteorological Society
Abstract: In this paper, we present trends in the verification scores of the Techniques Development Laboratory's (TDL's) operational guidance forecasts and the National Weather Service local forecasts made at Weather Service Forecast ...
