Intercomparison of the Performance of Operational Ocean Wave Forecasting Systems with Buoy Data
(American Meteorological Society, 2002)The monthly exchange of ocean wave model data has successfully been taking place among five operational weather centers. The data are compared with observations obtained from moored buoys and platforms. The analysis of 3 ... -
An Impact Study of Five Remotely Sensed and Five In Situ Data Types in the Eta Data Assimilation System
(American Meteorological Society, 2002)The impact of 10 data types used in the Eta Data Assimilation/Forecast System (EDAS) is studied for extended-length time periods during three seasons. Five of the data types are remotely sensed satellite data, and the other ... -
Description and Evaluation of a Hydrometeorological Forecast System for Mountainous Watersheds
(American Meteorological Society, 2002)This paper describes and evaluates an automated riverflow forecasting system for the prediction of peak flows during the cool season of 1998?99 over six watersheds in western Washington. The forecast system is based on the ... -
Verification of Precipitation Forecasts over the Alpine Region Using a High-Density Observing Network
(American Meteorological Society, 2002)The demand for verification of forecasting systems to ascertain their strengths and weaknesses is increasing dramatically as models evolve more rapidly. Precipitation forecasts have always been of great interest to forecasters ... -
Improved Detection Using Negative Elevation Angles for Mountaintop WSR-88Ds: Simulation of KMSX near Missoula, Montana
(American Meteorological Society, 2002)KMSX, near Missoula, Montana, is one of the Weather Surveillance Radars-1988 Doppler (WSR-88Ds) that are located on the top of a mountain. Because all WSR-88Ds employ scanning strategies that were developed for flatland ... -
The Canadian Updateable Model Output Statistics (UMOS) System: Design and Development Tests
(American Meteorological Society, 2002)The use of model output statistics (MOS) in operational weather element prediction has been hindered since the mid-1980s by frequent changes in the operational numerical weather prediction models that supply the predictors ... -
Initial Results of a Mesoscale Short-Range Ensemble Forecasting System over the Pacific Northwest
(American Meteorological Society, 2002)Motivated by the promising results of global-scale ensemble forecasting, a number of groups have attempted mesoscale, short-range ensemble forecasting (SREF), focusing mainly over the eastern half of the United States. To ... -
The Impact of Horizontal Resolution and Ensemble Size on Probabilistic Forecasts of Precipitation by the ECMWF Ensemble Prediction System
(American Meteorological Society, 2002)The effect of horizontal resolution and ensemble size on the ECMWF Ensemble Prediction System (EPS) is assessed for probabilistic forecasts of 24-h accumulated precipitation. Two sets of experiments are analyzed. The primary ... -

Comments on “An Operational Ingredients-Based Methodology for Forecasting Midlatitude Winter Season Precipitation”
(American Meteorological Society, 2002)Wetzel and Martin present an ingredients-based methodology for forecasting winter season precipitation. Although they are to be commended for offering a framework for winter-weather forecasting, disagreements arise with ... -
Some Meteorological Characteristics of Significant Tornado Events Occurring in Proximity to Flash Flooding
(American Meteorological Society, 2002)A study was performed to determine meteorological aspects of environments in which thunderstorms produced both strong or violent tornadoes and flash floods within a limited temporal and spatial domain. It was found that ... -
Validation and Use of GOES Sounder Moisture Information
(American Meteorological Society, 2002)The Geostationary Operational Environmental Satellite (GOES) sounders have provided quality hourly radiances and derived products over the continental United States and adjacent oceans for more than five years. The products ... -
Satellite Observations of a Severe Supercell Thunderstorm on 24 July 2000 Made during the GOES-11 Science Test
(American Meteorological Society, 2002)This paper utilizes a severe thunderstorm case from 24 July 2000 to demonstrate the relevance of Geostationary Operational Environmental Satellite (GOES) rapid-scan imagery and sounder data in the short-range forecasting ... -
An Intelligent User Interface to Support Weather Report Generation
(American Meteorological Society, 2002)Modern-day computers have greatly advanced our ability to generate reasonably accurate weather forecast models in a timely manner. High-powered workstations have put the output from these models, as well as a tremendous ... -
The Sensitivity of the Numerical Simulation of the Southwest Monsoon Boundary Layer to the Choice of PBL Turbulence Parameterization in MM5
(American Meteorological Society, 2002)Summertime convection over Arizona typically begins in the early afternoon and continues into the night. This suggests that the evolution of the daytime planetary boundary layer is important to the development of Arizona ... -
Warm Season Lightning Distributions over the Florida Peninsula as Related to Synoptic Patterns
(American Meteorological Society, 2002)Cloud-to-ground lightning data from the National Lightning Detection Network are examined over the Florida peninsula during the warm seasons of 1989 through 1998. The lightning data are stratified according to the location ... -
Norwegian-Type and Cold Front Aloft–Type Cyclones East of the Rocky Mountains
(American Meteorological Society, 2002)Conventional data and mesoscale model simulations are used to analyze two cyclones that developed east of the Rocky Mountains in June and November 1998. Both cyclones formed when a Pacific cold front overtook a lee ... -
