Short-Range Numerical Weather Prediction Using Time-Lagged Ensembles

Autor: Chungu Lu, Barry E. Schwartz, Huiling Yuan, Stanley G. Benjamin

Publikováno v: Weather and Forecasting. 22:580-595

A time-lagged ensemble forecast system is developed using a set of hourly initialized Rapid Update Cycle model deterministic forecasts. Both the ensemble-mean and probabilistic forecasts from this time-lagged ensemble system present a promising impro

The Value of Wind Profiler Data in U.S. Weather Forecasting

Autor: Steven E. Koch, Barry E. Schwartz, Edward J. Szoke, Stanley G. Benjamin

Publikováno v: Bulletin of the American Meteorological Society. 85:1871-1886

An assessment of the value of data from the NOAA Profiler Network (NPN) on weather forecasting is presented. A series of experiments was conducted using the Rapid Update Cycle (RUC) model/assimilation system in which various data sources were denied

Autor: Dongsoo Kim, Georg Grell, Barry E. Schwartz, Tracy Lorraine Smith, Tatiana G. Smirnova, Geoffrey S. Manikin, Kevin J. Brundage, Dezso Devenyi, John M. Brown, Stanley G. Benjamin, Stephen S. Weygandt

Publikováno v: Monthly Weather Review. 132:495-518

The Rapid Update Cycle (RUC), an operational regional analysis–forecast system among the suite of models at the National Centers for Environmental Prediction (NCEP), is distinctive in two primary aspects: its hourly assimilation cycle and its use o

Detecting environmental changes and trends

Autor: Elizabeth C Weatherhead, Amy J Stevermer, Barry E Schwartz

Publikováno v: Physics and Chemistry of the Earth, Parts A/B/C. 27:399-403

Detecting changes in climate variables is a difficult process that depends on several parameters. These parameters include not only the size of the trend and the accuracy of the measurements, but also the magnitude of variability and the autocorrelat

Accuracy of RUC-1 and RUC-2 Wind and Aircraft Trajectory Forecasts by Comparison with ACARS Observations

Autor: Stanley G. Benjamin, Barry E. Schwartz, Matt R. Jardin, Steven M. Green

Publikováno v: Weather and Forecasting. 15:313-326

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 assess differences in wind forec
