Improving Extraseasonal Summer Rainfall Prediction by Merging Information from GCMs and Observations
(American Meteorological Society, 2010)A new prediction approach for summer (June?August) rainfall in China was designed by considering both preceding observations and numerically predicted summer rainfall through a multivariate linear regression analysis. ... -
Summertime Precipitation Regimes Associated with the Sea Breeze and Land Breeze in Southern Mississippi and Eastern Louisiana
(American Meteorological Society, 2010)This study assesses the monthly climatology of the timing and placement of convective precipitation events induced by sea and land breezes in the Louisiana?Mississippi?Alabama region, and determines possible reasons for ... -
A Frequent-Updating Analysis System Based on Radar, Surface, and Mesoscale Model Data for the Beijing 2008 Forecast Demonstration Project
(American Meteorological Society, 2010)The Variational Doppler Radar Analysis System (VDRAS) was implemented in Beijing, China, and contributed to the Beijing 2008 Forecast Demonstration Project (B08FDP) in support of the Beijing Summer Olympics. VDRAS is a ... -
The Dynamic and Thermodynamic Structures Associated with a Series of Heavy Precipitation Events over China during January 2008
(American Meteorological Society, 2010)In the winter of 2008, China experienced once-in-50-yr (or once in 100 yr for some regions) snow and ice storms. These storms brought huge socio economical impacts upon the Chinese people and government. Although the storms ... -
TIGGE: Comparison of the Prediction of Northern Hemisphere Extratropical Cyclones by Different Ensemble Prediction Systems
(American Meteorological Society, 2010)The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble (TIGGE) is a World Weather Research Programme project. One of its main objectives is to enhance collaboration on the ... -
Characteristics of Summer Trade Wind Rainfall over Oahu
(American Meteorological Society, 2010)In this study, characteristics of summer trade wind rainfall over Oahu, Hawaii, are analyzed. In the early morning before sunrise, flow deceleration on the windward coastal area is the greatest when the island land surface ... -
Combining TRMM and Surface Observations of Precipitation: Technique and Validation over South America
(American Meteorological Society, 2010)The measure of atmospheric model performance is highly dependent on the quality of the observations used in the evaluation process. In the particular case of operational forecast centers, large-scale datasets must be made ... -
Tracking and Verification of East Atlantic Tropical Cyclone Genesis in the NCEP Global Ensemble: Case Studies during the NASA African Monsoon Multidisciplinary Analyses
(American Meteorological Society, 2010)This study evaluates the performance of the NCEP global ensemble forecast system in predicting the genesis and evolution of five named tropical cyclones and two unnamed nondeveloping tropical systems during the NASA African ... -
On the Orthogonalization of Bred Vectors
(American Meteorological Society, 2010)The key to the improvement of the quality of ensemble forecasts assessing the inherent flow uncertainties is the choice of the initial ensemble perturbations. To generate such perturbations, the breeding of growing modes ... -
Numerical Investigations on the Formation of Tropical Storm Debby during NAMMA-06
(American Meteorological Society, 2010)Mesoscale model forecasts were carried out beginning at 0000 UTC 19 August for simulating Tropical Disturbance 4, which was named Tropical Storm Debby on 22 August 2006. The Weather Research and Forecasting model, with ... -
Short-Term Convective Mode Evolution along Synoptic Boundaries
(American Meteorological Society, 2010)This paper investigates the relationships between short-term convective mode evolution, the orientations of vertical shear and mean wind vectors with respect to the initiating synoptic boundary, the motion of the boundary, ... -
Performance of NCEP Regional Wave Models in Predicting Peak Sea States during the 2005 North Atlantic Hurricane Season
(American Meteorological Society, 2010)Unprecedented numbers of tropical cyclones occurred in the North Atlantic Ocean and the Gulf of Mexico in 2005. This provides a unique opportunity to evaluate the performance of two operational regional wave forecasting ... -
The Meteorological Development Laboratory’s Aviation Weather Prediction System
(American Meteorological Society, 2010)The Meteorological Development Laboratory (MDL) has developed and implemented an aviation weather prediction system that runs each hour and produces forecast guidance for each hour into the future out to 25 h covering the ... -

Equitability Revisited: Why the “Equitable Threat Score” Is Not Equitable
(American Meteorological Society, 2009)In the forecasting of binary events, verification measures that are ?equitable? were defined by Gandin and Murphy to satisfy two requirements: 1) they award all random forecasting systems, including those that always issue ... -
Spring and Summer Midwestern Severe Weather Reports in Supercells Compared to Other Morphologies
(American Meteorological Society, 2010)This study compares severe weather reports associated with the nine convective system morphologies used in a recent study by Gallus et al. to an additional morphology, supercell storms. As in that previous study, all ... -
High-Resolution GEM-LAM Application in Marine Fog Prediction: Evaluation and Diagnosis
(American Meteorological Society, 2009)A three-level nested rendering of a high-resolution limited-area model version of the Global Environment Multiscale configuration (GEM-LAM), running quasi-operationally at the Canadian Meteorological Centre, is evaluated ...
