RISThe Relationship between Spread and Forecast Error in Extended-range Forecasts
Publisher: American Meteorological Society
Abstract: The relationship between ensemble forecast spread and ensemble forecast error is examined for a large number of extended range forecasts with a fairly simple, yet realistic model. A ?perfect model? approach is used so that ...
The Impact of Climatology and Systematic Errors upon the Skill of DERF Forecasts
Publisher: American Meteorological Society
Abstract: The average skill of 61 thirty-day forecasts of 500 mb geopotential height from the Dynamic Extended Range Forecast (DERF) experiment are investigated. These forecasts were made using the National Meteorological Center's ...
Quasi-Stationary Regimes in the Northern Hemisphere of the NCAR Community Climate Model
Publisher: American Meteorological Society
Abstract: The persistence of the planetary-scale circulation in a perpetual January experiment of the NCAR Community Climate Model is investigated. Pattern correlations between maps of 500 mb geopotential height are used to identify ...
The University of Utah Interactive Dynamics Program—One Approach to Interactive Access and Storage of Meteorological Data
Publisher: American Meteorological Society
Abstract: An interactive-software package has been developed in the University of Utah's Department of Meteorology to access and display meteorological data received via satellite broadcast. The retrieval of the meteorological data ...
Improved Detection Using Negative Elevation Angles for Mountaintop WSR-88Ds: Simulation of KMSX near Missoula, Montana
Publisher: American Meteorological Society
Abstract: KMSX, near Missoula, Montana, is one of the Weather Surveillance Radars-1988 Doppler (WSR-88Ds) that are located on the top of a mountain. Because all WSR-88Ds employ scanning strategies that were developed for flatland ...
