Ensemble Prediction System for Hydrometeorological Testbed (HMT) Application
AMeiyu front accompanied by a band of heavy precipitation in East Asia is typically characterized by a much larger moisture gradient than temperature gradient. Many previous studies have suggested use of equivalent potential temperature as a thermodynamic variable under this circumstance. However, dynamic variables coupled with such a thermodyna...
A quantitative comparison of automated and manual precipitation gage quality control techniques
Whereas automated quality control (QC) methods must rely on statistical measures and comparisons (e.g., neighbor checks), manual procedures often bring knowledge of physical causes for gage measurement failures (clogged or dripping gages, for example).This knowledge generally produces better judgments. On the other hand, quantitative techniques ...
The NWS Office of Hydrologic Development (OHD) operates the collection and dissemination of real-time Hydrometeorological Automated Data System (HADS) and other precipitation gauge data to the end-users at River Forecast Centers (RFCs) and Weather Forecast Offices (WFOs). As most of the data are delivered to the users with minimal quality contro...
Deployment of a differential absorption lidar (DIAL) water vapor system and a Doppler wind lidar on a Falcon research aircraft provided direct, high spatial resolution profiles of northerly water vapor transport over the southern Great Plains during the IHOP field experiment. The observations, with horizontal resolution of 1.5 km and vertical re...
Two aircraft missions during the International H20 Project (IHOP; Weckwerth et al. 2004) in Oklahoma and Kansas during 2002 were dedicated to multi-scale observations of the Central Plains low-level jet (LLJ). A particular objective during these flights was a determination of the inherent scales of moisture flux within the LLJ. To accomplish thi...
THE HURRICANE-FLOOD-LANDSLIDE CONTINUUM - Forecasting Hurricane Effects at Landfall
In the 10 days of 21-30 September 1998, Hurricane Georges left a trail of destruction in the Caribbean region and U.S. Gulf Coast. Subsequently, in the same year, Hurricane Mitch caused widespread destruction and loss of life in four Central American nations, and in 1999 a tropical depression impacted the north coast of Venezuela causing hundred...
A PV-streamer's role in a succession of heavy rain-producing MCSs over the central United States
A PV-streamer at 250 hPa, moving over the west central United States 25 June-5 July 1999 was visible on GOES-8 water vapor imagery as a narrow, elongated dark band. It sparked a series of mesoscale convective systems (MCSs) on successive days, producing heavy precipitation from Nebraska eastward and southeastward toward the coast along the Gul...

Pseudo-Precipitation: A Continuous Precipitation Variable
The discontinuous and highly nonlinear nature of precipitation makes its statistical manipulation, like the reduction of bias in quantitative precipitation forecasts (QPF) or probabilistic QPF (PQPF) problematic. To ease the statistical post-processing of precipitation, a new continuous variable, pseudo-precipitation (PP) is introduced. Pseudo- ...
