Lightning from Two National Detection Networks Related to Vertically Integrated Liquid and Echo-Top Information from WSR-88D Radar
(American Meteorological Society, 1995)Two national cloud-to-ground (CG) lightning-detection systems were operating across the contiguous United States during 1993. These two networks are compared to each other and to WSR-88D radar information collected by the ... -
A Climatology of the Warm Season Great Plains Low-Level Jet Using Wind Profiler Observations
(American Meteorological Society, 1995)Hourly observations from the Wind Profiler Demonstration Network during the warm season months of 1991 and 1992 were used to develop a climatology of the low-level jet (LLJ) over the Great Plains of the central United ... -
Surface Wind Comparisons with Radar Wind Profiler Observations near Tropical Cyclones
(American Meteorological Society, 1995)A special set of radar wind profiler observations during the Tropical Cyclone Motion (TCM-90) field experiment is used to relate lower-tropospheric winds to surface sustained winds and gusts on the west coast of Okinawa. ... -
Error Climatology of the 80-Wave Medium-Range Forecast Model
(American Meteorological Society, 1995)A climatology of the once-daily (0000 UTC) 1000-hPa error fields of the National Meteorological Center's 80-wave Medium-Range Forecast (MRF) model is studied. An analysis of the error field has been conducted over the ... -
A Comparison of Temperature and Wind Measurements from ACARS-Equipped Aircraft and Rawinsondes
(American Meteorological Society, 1995)A comparison was made of temperature and wind observations reported by rawinsonde and Aircraft Communications, Addressing, and Reporting System (ACARS)-equipped commercial aircraft separated by less than 150 km in distance ... -
Verification of Official Monthly Mean 700-hPa Height Forecasts: An Update
(American Meteorological Society, 1995)Quality analyses have been performed on a 21-yr record of monthly mean Northern Hemisphere extratropical 700-hPa height anomaly forecasts issued by the National Weather Service. A positive trend in skill noted a decade ago ... -
Evaluation of 33 Years of Quantitative Precipitation Forecasting at the NMC
(American Meteorological Society, 1995)The National Meteorological Center (NMC) initiated Quantitative Precipitation Forecasts (QPF) and an intensive QPF verification program in 1960. These forecast products have evolved from a manual effort, relying on extensive ... -
NOAA Weather Radio as an Emergency Communication Vehicle in West Tennessee
(American Meteorological Society, 1995)In March 1994, a telephone survey was conducted in west Tennessee to determine the extent to which NOAA Weather Radio (NWR) is used by residents of the region. Interviews were completed with 407 respondents for an error ... -
Modernization in the National Weather Service River and Flood Program
(American Meteorological Society, 1995)Hydrologic forecasting is vital not only to the National Weather Service mission of saying lives and protecting property but also to our nation's water management decision makers. Since its inception, the River and Flood ... -
Operational Responsibilities of the National Weather Service River and Flood Program
(American Meteorological Society, 1995)The River and Flood Program in the National Weather Service, in its mission to save lives and property, has the responsibility to gather hydrologic data from a variety of sources and to assemble the data to make timely and ... -
Organization of the River and Flood Program in the National Weather Service
(American Meteorological Society, 1995)The National Weather Service is charged by law with the responsibility of issuing forecasts and warnings of floods to the nation to help save lives and mitigate property damage. This mission falls under the authority of ... -
An Interesting Mesoscale Storm-Environment Interaction Observed Just Prior to Changes in Severe Storm Behavior
(American Meteorological Society, 1995)Satellite images are presented to illustrate an interesting interaction that occurred between a severe thunderstorm and a mesoscale feature that originated in its nearby environment. Immediately following that interaction, ... -
The Thermal Energy Equivalent of a Skew T “Box”
(American Meteorological Society, 1995)No abstract available -
Documentation of a Systematic Bias in the Aviation Model's Forecast of the Atlantic Tropical Upper-Tropospheric Trough: Implications for Tropical Cyclone Forecasting
(American Meteorological Society, 1995)This study uncovers what appears to be a systematic bias in the National Meteorological Center's aviation (AVN) model at 200 mb over the Caribbean Sea. In general, the 48-h forecast in the vicinity of the Tropical Upper ... -
Improving Seasonal Hurricane Predictions for the Atlantic Basin
(American Meteorological Society, 1995)This paper demonstrates that improved forecasts of the annual number of hurricanes in the Atlantic tropical basin are possible by separating tropical-only hurricanes from hurricanes influenced by extratropical factors. It ... -
Improvement of Numerical Prediction of Typhoon Tracks in the Western North Pacific Basin near Taiwan
(American Meteorological Society, 1995)In an effort to improve the tropical cyclone track forecast, two preprocessing procedures are applied to an operational baroclinic forecast system at the Central Weather Bureau (CWB) in Taipei. The first replaces the ... -
Performance of Global and Regional NWP Models in Their Prediction of Typhoon Nat (1991)
(American Meteorological Society, 1995)In 1991, Typhoon Nat over the western North Pacific made four directional reversals due to its interactions with two other tropical cyclones (TCs), Luke and Mireille. This paper analyzes the performance of three global and ... -
Simulation of an Observed Squall Line with a Meso-Beta-Scale Hydrostatic Model
(American Meteorological Society, 1995)This paper reports on simulations of an observed squall line with the meso-beta-scale hydrostatic PERIDOT model. An attempt is made to answer the question of what model changes are necessary to roughly simulate a squall ... -
The Use of Volumetric Radar Reflectivity Predictors in the Development of a Second-Generation Severe Weather Potential Algorithm
(American Meteorological Society, 1995)The operational WSR-88D Severe Weather Potential (SWP) algorithm is an automated nowcasting procedure aimed at providing guidance in the detection of severe local storms. It yields a numerical index proportional to the ... -
