Regeneration of the Southerly Buster of Southeast Australia
(American Meteorological Society, 2000)The southerly buster has been successfully simulated using a numerical weather prediction (NWP) model and verified (particularly the sea level pressure field). This simulation was then used to study the behavior of the ... -
Multiscale Overview of a Violent Tornado Outbreak with Attendant Flash Flooding
(American Meteorological Society, 2000)On 1 March 1997 violent tornadoes caused numerous fatalities and widespread damage across portions of central and eastern Arkansas and western Tennessee. In addition, the associated thunderstorms produced very heavy rainfall ... -
A Quantitative Assessment of the NESDIS Auto-Estimator
(American Meteorological Society, 2000)A systematic evaluation of the National Environmental Satellite, Data and Information Service Auto-Estimator (A-E), a satellite-based algorithm for the estimation of rainfall, was performed for a 13-month period ending ... -
Extratropical Transition of Western North Pacific Tropical Cyclones: An Overview and Conceptual Model of the Transformation Stage
(American Meteorological Society, 2000)Extratropical transition (ET) in the western North Pacific is defined here in terms of two stages: transformation, in which the tropical cyclone evolves into a baroclinic storm; and reintensification, where the transformed ... -

Supertyphoon Forrest (September 1983): The Overlooked Record Holder of Intensification in 24, 36, and 48 h
(American Meteorological Society, 2000)Reanalysis of aircraft reconnaissance data shows that in September 1983 Supertyphoon Forrest reached a sea level pressure of 876 hPa instead of 883 hPa as previously accepted. It is estimated that at the time, Forrest was ... -
Applying the Betts–Miller–Janjic Scheme of Convection in Prediction of the Indian Monsoon
(American Meteorological Society, 2000)The performance of the Betts?Miller?Janjic scheme of convection has been investigated for prediction of the Indian monsoons. For this purpose a limited area numerical weather prediction model with two schemes of convection, ... -
A Diagnosis of Tropospheric Effects upon Surface Precipitation Amount for a Sample of East Coast Snowstorms
(American Meteorological Society, 2000)Upper-air variables have been correlated with near-simultaneous precipitation observations from 35 winter storms that produced heavy snowfall in the eastern coastal region of the United States. Standard radiosonde observations ... -
Radar Data Processing and Visualization over Complex Terrain
(American Meteorological Society, 2000)MountainZebra is a data flow configuration that processes and displays radar data over complex terrain. The system combines three elements: the data stream from an operational radar, 3D topographical information, and the ... -
Accuracy of RUC-1 and RUC-2 Wind and Aircraft Trajectory Forecasts by Comparison with ACARS Observations
(American Meteorological Society, 2000)As part of an investigation into terminal airspace productivity sponsored by the NASA Ames Research Center, a study was performed at the Forecast Systems Laboratory to investigate sources of wind forecast error and to ... -
Real-Time Prediction of the Lake Breeze on the Western Shore of Lake Michigan
(American Meteorological Society, 2000)A forecast verification study of the occurrence and inland penetration of the lake breeze on the western shore of Lake Michigan was conducted. A real-time version of The Pennsylvania State University?National Center for ... -
The Application of Synoptic Stratification to Precipitation Forecasting in the Trade Wind Regime
(American Meteorological Society, 2000)A 1129-day high quality rainfall dataset was collated, from the months of March to November 1993?97, where trade wind flow predominates across the northeast Queensland tropical coast. This dataset was matched with numerical ... -
Operational Implementation of the Fritsch–Chappell Convective Scheme in the 24-km Canadian Regional Model
(American Meteorological Society, 2000)The objective and subjective evaluations that led to the implementation of the Fritsch and Chappell (FC) convective scheme in the new 24-km Canadian operational regional model are described in this study. Objective ... -
A Static Stability Index for Low-Topped Convection
(American Meteorological Society, 2000)Static stability indexes provide a simple representation of a complex aspect of the atmosphere and are widely used in operational forecasting. However, their applicability is limited, since most are specifically designed ... -
Improving Tropical Cyclone Intensity Guidance in the Eastern North Pacific
(American Meteorological Society, 2000)The primary objective of this research is the development of a statistical model that will provide tropical cyclone (TC) intensity guidance for the eastern North Pacific (ENP) superior to that provided by climatology and ... -
Use of the “Odds Ratio” for Diagnosing Forecast Skill
(American Meteorological Society, 2000)This study investigates ways of quantifying the skill in forecasts of dichotomous weather events. The odds ratio, widely used in medical studies, can provide a powerful way of testing the association between categorical ... -
Improved WSR-88D Scanning Strategies for Convective Storms
(American Meteorological Society, 2000)The Weather Surveillance Radar-1988 Doppler (WSR-88D) is an important operational and research tool for detecting and monitoring convective storms. Two scanning strategies, or volume coverage patterns, VCP 11 and 21, are ... -
Conditional Instability and Shear for Six Hurricanes over the Atlantic Ocean
(American Meteorological Society, 2000)One hundred and thirty Omega dropwindsondes deployed within 500-km radius of the eye of six North Atlantic hurricanes are used to determine the magnitudes and trends in convective available potential energy, and 10?1500-m ...
