Characteristics of Surface Cyclone Forecasts in the Aviation Run of the Global Spectral Model
Publisher: American Meteorological Society
Abstract: The performance of the Aviation Run (AVN) of the National Meteorological Center's (NMC) Global Spectral Model (GSM) in predicting surface cyclones was examined during the autumn of 1990 through the winter of 1992, a period ...
Cloud Distributions in a Bay of Bengal Monsoon Depression
Publisher: American Meteorological Society
Abstract: A monsoon depression over the Bay of Bengal on 7 July 1979 has been studied using a variety of observations, in particular, cloud photographs from aircraft. Ascent in the lower troposphere was concentrated in mesoscale ...
Standardized Anomalies Applied to Significant Cold Season Weather Events: Preliminary Findings
Publisher: American Meteorological Society
Abstract: Forecasting significant weather events, such as floods, heat waves, arctic outbreaks, ice storms, large severe weather outbreaks, and major winter storms, is a critical function for all weather services. However, conventional ...
The Prediction of Rapidly Deepening Cyclones by NMC's Nested Grid Model: Winter 1989–Autumn 1991
Publisher: American Meteorological Society
Abstract: A study of rapidly deepening cyclones (RDC) produced by the National Meteorological Center's (NMC) Nested Grid Model (NGM) was conducted over a three-year period from the winter of 1988/89 through the autumn of 1991. The ...
Systematic Model Forecast Errors of Surface Cyclones in the NGM and AVN, January 1990
Publisher: American Meteorological Society
Abstract: Results from a study examining the performance of the nested grid model (NGM) and the aviation run of the global spectral model (AVN) in predicting surface cyclones during January 1990 revealed that the AVN slightly ...
Systematic Surface Anticyclone Errors in Nested Grid Model Run at NMC: December 1988–August 1989
Publisher: American Meteorological Society
Abstract: 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 ...
Mesoscale Band Formation in Three Major Northeastern United States Snowstorms
Publisher: American Meteorological Society
Abstract: The National Centers for Environmental Prediction?s 29-km version Meso Eta Model and Weather Surveillance Radar-1988 Doppler base reflectivity data were used to diagnose intense mesoscale snowbands in three northeastern ...
Using Wind Anomalies to Forecast East Coast Winter Storms
Publisher: American Meteorological Society
Abstract: Forecasting major winter storms is a critical function for all weather services. Conventional model-derived fields from numerical weather prediction models most frequently utilized by operational forecasters, such as ...
Utilizing Normalized Anomalies to Assess Synoptic-Scale Weather Events in the Western United States
Publisher: American Meteorological Society
Abstract: Synoptic-scale weather events over the western United States are objectively ranked based on their associated tropospheric anomalies. Data from the NCEP 6-h reanalysis fields from 1948 to 2006 are compared to a 30-yr ...
