Validation of ECMWF Sea Level Pressure Analyses over the Bellingshausen Sea, Antarctica
(American Meteorological Society, 2003)Surface pressure measurements from instruments deployed on ice floes in the southern Bellingshausen Sea were used to assess the accuracy of European Centre for Medium-Range Weather Forecasts (ECMWF) analyses in this region ... -
Refined Supercell and Tornado Forecast Parameters
(American Meteorological Society, 2003)This note updates a previous study that utilized a baseline climatology of soundings associated with large hail, significant tornadoes, and 10 or more cloud-to-ground lightning flashes from 1992. Expanding on the earlier ... -
Whither the Weather Analysis and Forecasting Process?
(American Meteorological Society, 2003)An argument is made that if human forecasters are to continue to maintain a skill advantage over steadily improving model and guidance forecasts, then ways have to be found to prevent the deterioration of forecaster skills ... -
Severe Convective Windstorms over the Northern High Plains of the United States
(American Meteorological Society, 2003)During the warm seasons (May?September) of 1996?99, Weather Surveillance Radar-1988 Doppler (WSR-88D) data and severe wind reports (either gusts >25 m s?1, or damage-related reports) over the northern High Plains (NHP) of ... -
Analysis of Three Situations of the Foehn Effect over the Andes (Zonda Wind) Using the Eta–CPTEC Regional Model
(American Meteorological Society, 2003)The zonda is a warm and extremely dry wind that occurs east of the Andes Cordillera in the extratropical latitudes of South America. Its orographic origin is similar to the foehn that blows in Germany and Austria and the ... -
Multiseason Verification of the MM5. Part II: Evaluation of High-Resolution Precipitation Forecasts over the Northeastern United States
(American Meteorological Society, 2003)This paper evaluates the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5) precipitation forecasts over the northeastern United States to show the effects of ... -
Multiseason Verification of the MM5. Part I: Comparison with the Eta Model over the Central and Eastern United States and Impact of MM5 Resolution
(American Meteorological Society, 2003)This paper describes the multiseason verification of the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5) and the National Centers for Environmental Prediction ... -
Depiction of Upper-Level Precursors of the December 1999 Storms from TOVS Observations
(American Meteorological Society, 2003)At the end of December 1999, two extremely severe storms only one day apart affected western Europe and caused considerable damage. A variable derived from satellite observations, the so-called temperature of the lower ... -
Assessment of Implementing Satellite-Derived Land Cover Data in the Eta Model
(American Meteorological Society, 2003)One of the challenges in land surface modeling involves specifying accurately the initial state of the land surface. Most efforts have focused upon using a multiyear climatology to specify the fractional coverage of ... -
Improved Detection Using Negative Elevation Angles for Mountaintop WSR-88Ds. Part II: Simulations of the Three Radars Covering Utah
(American Meteorological Society, 2003)About one-third of the Weather Surveillance Radar-1988 Doppler (WSR-88D) radars located in the western third of the United States are on the tops of mountains. These mountaintop radars employ scanning strategies that were ... -

The Rapid Intensification and Subsequent Rapid Weakening of Hurricane Lili as Compared with Historical Hurricanes
(American Meteorological Society, 2003)The purpose of this paper is to compare the rapid intensification and rapid decay of Hurricane Lili with historical records to determine whether similar events have occurred in the past. Data for this study were compiled ... -
The Evolution of Morning Convective Systems over the U.S. Great Plains during the Warm Season. Part I: The Forecast Problem
(American Meteorological Society, 2003)The factors that influence the evolution of convective systems during the late morning over much of the Great Plains are not understood well. It is known that in this region the majority of such systems dissipate or decrease ... -
Precipitation Efficiency of Warm-Season Midwestern Mesoscale Convective Systems
(American Meteorological Society, 2003)The precipitation efficiencies for mesoscale convective systems (MCS) over the central United States are calculated. During July?September 2000 and June?September 2001, 24 MCS for which sufficient data were available ... -
Characteristics of Vertical Wind Profiles near Supercells Obtained from the Rapid Update Cycle
(American Meteorological Society, 2003)Over 400 vertical wind profiles in close proximity to nontornadic and tornadic supercell thunderstorms are examined. The profiles were obtained from the Rapid Update Cycle (RUC) model/analysis system. Ground-relative wind ... -
Close Proximity Soundings within Supercell Environments Obtained from the Rapid Update Cycle
(American Meteorological Society, 2003)A sample of 413 soundings in close proximity to tornadic and nontornadic supercells is examined. The soundings were obtained from hourly analyses generated by the 40-km Rapid Update Cycle-2 (RUC-2) analysis and forecast ... -
The Impact of Radar Data on Short-Term Forecasts of Surface Temperature, Dewpoint Depression, and Wind Speed
(American Meteorological Society, 2003)A statistical system that uses surface observations and radar data to provide 1-, 3-, and 6-h forecasts of temperature, dewpoint depression, and wind speed is developed. Application of the system to independent data ...
