Hurricane Dennis Simulations By Using Various Initial Conditions and WRF Dynamic Cores
In this paper an attempt has been made to evaluate simulations of Hurricane Dennis performed by using various dynamic cores and initial conditions. Dennis has formed from a tropical wave that moved westward from the coast of Africa on 29 June, 2005. It developed and reached tropical storm strength on 5 July. The storm then rapidly intensified in...
Short-range quantitative precipitation forecasts (QPF) not only provide useful weather information, they also add value to river forecasts. This study investigates the usefulness of high-resolution QPF in simulating streamflow over the North Fork of the American River Basin in Northern California through a spatially distributed hydrologic model....
Hurricane Dennis Simulation By Using Various Initial and Boundary Conditions with HRPS
In this paper, an attempt has been made to evaluate the performance of the Hurricane Research Prediction System (HRPS) developed at the Atlantic Oceanic and Meteorological Laboratory based on the sensitivity of different model domain sizes, and various background fields associated with forecasts for Hurricane Dennis. Dennis central pressure fell...
Recovery of mesoscale covariance using time-phased ensembles
Diagnosis and optimization of ensemble forecasts
In the current study, a technique that offers a way to evaluate ensemble forecast uncertainties produced either by initial conditions or different model versions, or both, is presented. The technique consists of first diagnosing the performance of the forecast ensemble and then optimizing the ensemble forecast using results of the diagnosis. Th...
Recovery of mesoscale covariance using time-phased ensembles
Recovery of mesoscale covariance using time-phased ensembles
One of the most important factors that determines meteorological analysis fields in a data assimilation system is the background covariance matrix. Not only do the correlations in this background covariance matrix perform the spatial spreading of information at the observation points throughout the model domain including data-sparse areas, but t...
The impact of precipitation dataset choices on analyses and forecast verification during the HMT
Over the continental United States, a variety of different sources of precipitation observations and estimates are available for use as verification datasets and as input to hydrologic forecast models. These range from radar and satellite estimates, generally available in continuous spatial grids, to gauge networks of varying spatial and tempora...
The NOAA Hydrometeorological Testbed (HMT) program (http://hmt.noaa.gov) is a long-term project, which links the research community with the operational weather and hydrological forecasting. The HMT-West winter experiments focus on the winter storms over the American River Basin (ARB) of Northern California. The NOAA/ESRL/GSD operated a time-lag...

Recovery of Flow-Dependent Model Error Covariance from Time-Phased, Multi-Model Ensembles
A high-resolution (9-km) diabatic data assimilation system-the Local Analysis and Prediction System (LAPS), has been developed and used to initialize the real-time fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) at the Central Weather Bureau in Taiwan. During 2003, the more...

Local-domain mesoscale analysis and forecast model support for the 1996 Centennial Olympic Games
The National Weather Service (NWS) developed the Olympic Weather Support System (OWSS) to provide specialized operational weather support for the 1996 Centennial Olympic Games in Atlanta. Operation implementation of the National Oceanic and Atmospheric Administration Forecast Systems Laboratory's Local Analysis and Prediction System (LAPS) was ...

Convective storm nowcasting using the Space-Time Meso Analysis System
The detection of narrow zones of low-level convergence (or boundaries) critically important for thunderstorm initiation, development and evolution are primary objectives of automated nowcasting systems. The Space-Time Meso Analysis System (STMAS) has been developed at the NOAA Earth System Research Laboratory to take full advantage of the nearly...
