Upper-level Forcing of Explosive Cyclogenesis Over the Ocean Based on Operationally Analyzed Fields
(American Meteorological Society, 1988)Some of the recent research studies of explosive extratropical cyclogenesis have been based on detailed soundings or special reconstructions of the evolution in poststorm analysis. The focus of this cyclogenesis study is ... -
Opposing Mesoscale Circulations: A Case Study
(American Meteorological Society, 1988)Two mesoscale convective systems developed over the central plains in and near the OK PRE-STORM observing network on 23?24 June 1985. Mesoscale outflows from these two systems collided in central Kansas at 0430 UTC 24 June. ... -
Convective Tendency Images Derived from a Combination of Lightning and Satellite Data
(American Meteorological Society, 1988)A technique is presented for generating convective tendency products by combining satellite images with observations of cloud-to-ground lightning activity. Rapid scan (5-min) infrared satellite images are used to define ... -
Corrigendum
(American Meteorological Society, 1988)Correction to Weather and Forecasting, Volume 2, Issue 1, page 17. -
Basis for the Forecast for Summer 1987 Following a Radically Different Spring
(American Meteorological Society, 1988)This paper describes and partially explains the unusual development of an anomalous summer circulation and weather pattern in 1987 following a spring that had much different characteristics. Since the forecast for this ... -
A Statistical Comparison of Methods for Determining Ocean Surface Winds
(American Meteorological Society, 1988)The performance of various techniques which determine ocean surface winds using information from large-scale analyses and forecast models is discussed. The techniques evaluated are the geostrophic relation, a simple empirical ... -
A Short-Range Forecasting Experiment Conducted during the Canadian Atlantic Storms Program
(American Meteorological Society, 1988)During the Canadian Atlantic Storms Program (CASP), a dedicated forecast center conducted experiments in mesoscale forecasting. Several forecast products, including a marine forecast and a site-specific public forecast, ... -
A Comparison of Three Radar-Based Severe-Storm-Detection Algorithms on Colorado High Plains Thunderstorms
(American Meteorological Society, 1988)Volumetric reflectivity data collected with the National Center for Atmospheric Research's (NCAR) 10-cm Doppler radar during the Program for Regional Observing and Forecasting Services (PROFS) 1985 Real-Time Forecast ... -
Forcing Mechanisms and Other Characteristics of Significant Summertime Precipitation
(American Meteorological Society, 1988)Satellite, radar, surface, and upper-air data from the June?August periods of 1982?83 are examined to determine the mechanisms, and their relative contributions, for producing warm-season precipitation in the United States. ... -
Real-Time Short-Term Forecasting of Precipitation at an Australian Tropical Station
(American Meteorological Society, 1988)The results of a major real-time trial of techniques for the short-term (12 h ahead) prediction of precipitation for the Australian tropical city of Darwin are described. The trial compared current operational manual ... -
Application of Seasat Scatterometer Wind Measurements for Operational Short-Range Weather Forecasting
(American Meteorological Society, 1988)The availability of the Seasat Scatterometer provided the first opportunity to study the impact of adding satellite-derived surface wind data to short-range regional analyses and forecasts. Six cases on the west coast of ... -
Evaluation of Western North Pacific Tropical Cyclone Objective Forecast Aids
(American Meteorological Society, 1988)The Joint Typhoon Warning Center's (JTWC) official and objective aid forecasts for the western North Pacific tropical cyclones during 1978?85 are evaluated. Forecast accuracy is measured by the forecast error, cross-track ... -
Long-Range Weather Prediction: Limits of Predictability and Beyond
(American Meteorological Society, 1988)The details of the weather are not predictable beyond one to two weeks. At longer time ranges, averages of the weather over space and time can be usefully predicted only to the extent that the variations of the averages ... -
Mesoscale and Synoptic Scale Interactions Leading to Intense Convection: The Case of 7 June 1982
(American Meteorological Society, 1988)A case study is presented involving an unusually intense mesoscale convective system (MCS) which produced extensive hail and wind damage in northeast Kansas and northern Missouri, including the Kansas City metropolitan ... -
Use of VAS Data to Diagnose the Mesoscale Environment of Convective Storms
(American Meteorological Society, 1988)The utility of VISSR Atmospheric Sounder (VAS) retrieval datasets for mesoscale analysis is explored. A detailed mesoscale air mass analysis method is presented in which VAS soundings, satellite imagery, and conventional ... -
Three-Dimensional Airflow and Precipitation Structure in a Nondeepening Cyclone
(American Meteorological Society, 1988)During the period 1200 UTC 3 March to 1200 UTC 5 March 1985 a cyclone located over eastern Colorado tracked northeastward across the Great Plains to southern Ontario. Although the low-pressure system decayed considerably ... -
Objectively Forecasting Sunshine
(American Meteorological Society, 1988)Statistical regression was used to relate observations of the percent of possible sunshine to objective cloud forecasts. A multiple linear regression equation was developed and later applied to produce forecasts of the ... -

A Decision Tree Method of Forecasting Thunderstorms, Severe Thunderstorms and Tornadoes
(American Meteorological Society, 1987)A decision tree approach to forecasting thunderstorms, severe thunderstorms and tornadoes is described which uses only meteorological parameters considered essential for these phenomena to develop. The physical relevance ... -
Skill of NMC Operational Dynamical Models in Prediction of Explosive Cyclogenesis
(American Meteorological Society, 1987)The skill of the Nested-Grid Model (NGM) and the global spectral model (GLBL) at the National Meterological Center in the prediction of explosive cyclogenesis was evaluated for the period 1 September 1986?30 April 1987. ...
