Analysis of the Record Mesosnowfall Event of 1997 in Central Mississippi
(American Meteorological Society, 2001)Although rare, heavy snowfalls in the southern United States have significant impact and are often associated with distinct surface low pressure systems. However, the central Mississippi record snowfall event of 14 December ... -
Standardized Anomalies Applied to Significant Cold Season Weather Events: Preliminary Findings
(American Meteorological Society, 2001)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 ... -
High-Resolution GOES-8 Visible and Infrared Cloud Frequency Composites over Northern Florida during the Summers 1996–99
(American Meteorological Society, 2001)GOES-8 visible and infrared cloud frequency composites have been created from imagery collected during June, July, and August for the years 1996?99 over northern Florida. These cloud frequency composites are unique because ... -
Error Evaluation of NCEP and LAHM Regional Model Daily Forecasts over Southern South America
(American Meteorological Society, 2001)NCEP short-range operational forecast and Limited Area HIBU (Federal Hydrometeorological Institute and Belgrade University) Model (LAHM) regional model performance during a 2-month period over the southern part of South ... -
Impact of Improved Initialization of Mesoscale Features on Convective System Rainfall in 10-km Eta Simulations
(American Meteorological Society, 2001)A 10-km version of the NCEP Eta Model has been run over a roughly 1000 km ? 1000 km domain centered over the upper Midwest for 20 cases where heavy warm season rainfall occurred from mesoscale convective systems to investigate ... -
An Automated System for the Analysis of Gravity Waves and Other Mesoscale Phenomena
(American Meteorological Society, 2001)An automated near-real-time system for the surface analysis of gravity waves and other mesoscale phenomena is developed, tested, and applied to several cases. Five-minute observations from the Automated Surface Observing ... -
Some Common Ingredients for Heavy Orographic Rainfall
(American Meteorological Society, 2001)The purpose of this paper is to synthesize some common synoptic and mesoscale environments conducive to heavy orographic rainfall. Previous studies of U.S. and Alpine cases and new analyses of some Alpine and east Asian ... -
Correlation of Real and Model Wind Speeds in Different Terrains
(American Meteorological Society, 2001)Wind speeds over a 6-month period from 21 surface stations, 3 upper-wind stations, and 2 different models are compared. Similar data are used for three different topographic regions of New Zealand broadly classed as having ... -
Verification of the ECMWF Ensemble Prediction System Forecasts: A Study of Large-Scale Patterns
(American Meteorological Society, 2001)The aim of this work is the evaluation of some basic measures of skill of the Ensemble Prediction System used operationally at the European Centre for Medium-Range Weather Forecasts. Probabilistic forecasts for the occurrence ... -
A Bayesian Neural Network for Severe-Hail Size Prediction
(American Meteorological Society, 2001)The National Severe Storms Laboratory has developed algorithms that compute a number of Doppler radar and environmental attributes known to be relevant for the detection/prediction of severe hail. Based on these attributes, ... -
Evaluation of COAMPS Forecasts of Coastal Stratus Using Satellite Microphysical Retrievals and Aircraft Measurements
(American Meteorological Society, 2001)A field project was carried out offshore of central Oregon during August 1999 to evaluate mesoscale model simulations of coastal stratiform cloud layers. Procedures for mapping cloud physical parameters such as cloud optical ... -
