An Observational Study of Derecho-Producing Convective Systems
(American Meteorological Society, 2004)This study identifies the common large-scale environments associated with the development of derecho- producing convective systems (DCSs) from a large number of events. Patterns are identified using statistical clustering ... -
On the Relationship of Tornado Path Length and Width to Intensity
(American Meteorological Society, 2004)Reported path lengths and widths of tornadoes have been modeled using Weibull distributions for different Fujita (F) scale values. The fits are good over a wide range of lengths and widths. Path length and width tend to ... -
A 10-Yr Climatology Relating the Locations of Reported Tornadoes to the Quadrants of Upper-Level Jet Streaks
(American Meteorological Society, 2004)Observations and numerical model simulations associate rising motions below the right-entrance and left-exit quadrants of an upper-level straight jet streak with the development of convection and severe weather. The ... -
The Relationship between Meteorological Parameters and Daily Summer Rainfall Amount and Coverage in West-Central Florida
(American Meteorological Society, 2004)Considerable daily variations of summer convective rainfall average areal coverage and rainfall amount were identified in west-central Florida for the period May?September 1997?2000 using a 29-site rainfall network. Pearson ... -
Simulation of the New England Sea Breeze: The Effect of Grid Spacing
(American Meteorological Society, 2004)The fifth-generation Pennsylvania State University?National Center for Atmospheric Research (Penn State? NCAR) Mesoscale Model (MM5) was run for seven cases from 2001 in which a sea breeze develops along the eastern New ... -
Hydrologic Scales, Cloud Variability, Remote Sensing, and Models: Implications for Forecasting Snowmelt and Streamflow
(American Meteorological Society, 2004)Accurate prediction of available water supply from snowmelt is needed if the myriad of human, environmental, agricultural, and industrial demands for water are to be satisfied, especially given legislatively imposed ... -
A Damaging Downburst Prediction and Detection Algorithm for the WSR-88D
(American Meteorological Society, 2004)The problem of predicting the onset of damaging downburst winds from high-reflectivity storm cells that develop in an environment of weak vertical shear with Weather Surveillance Radar-1988 Doppler (WSR-88D) is examined. ... -
Real-Time Implementation of Single-Doppler Radar Analysis Methods for Tropical Cyclones: Algorithm Improvements and Use with WSR-88D Display Data
(American Meteorological Society, 2004)The NOAA/NWS/NCEP/Tropical Prediction Center/National Hurricane Center has sought techniques that use single-Doppler radar data to estimate the tropical cyclone wind field. A cooperative effort with NOAA/Atlantic Oceanographic ... -
An Evaluation of Mesoscale-Model-Based Model Output Statistics (MOS) during the 2002 Olympic and Paralympic Winter Games
(American Meteorological Society, 2004)The skill of a mesoscale-model-based model output statistics (MOS) system that provided hourly forecasts for 18 sites over northern Utah during the 2002 Winter Olympic and Paralympic Games is evaluated. The MOS system was ... -
Wind Forecasting for the Sailing Events at the Sydney 2000 Olympic and Paralympic Games
(American Meteorological Society, 2004)The Australian Bureau of Meteorology was the official provider of weather services for the 2000 Olympic and Paralympic Games in Sydney, Australia. The sailing events took place on Sydney Harbor and an offshore area adjacent ... -
The Societal, Social, and Economic Impacts of the World Weather Research Programme Sydney 2000 Forecast Demonstration Project (WWRP S2000 FDP)
(American Meteorological Society, 2004)The Sydney 2000 (S2000) Forecast Demonstration Project (FDP) was initiated by the World Meteorological Organization (WMO) World Weather Research Programme (WWRP) to enable the world meteorological community to cooperatively ... -
Analysis and Forecasting of the Low-Level Wind during the Sydney 2000 Forecast Demonstration Project
(American Meteorological Society, 2004)During the Sydney 2000 Forecast Demonstration Project (FDP) a four-dimensional variational assimilation (4DVAR) scheme was run to analyze the low-level wind field with high spatial and temporal resolution. The 4DVAR scheme ... -
Sydney 2000 Forecast Demonstration Project: Convective Storm Nowcasting
(American Meteorological Society, 2004)Five of the nowcasting systems that were available during the Sydney 2000 Forecast Demonstration Project (FDP) were selected for evaluation. These systems, from the United States, the United Kingdom, and Australia, had the ... -
