RISPredictability Experiments Using a High-Resolution Limited-Area Model
Publisher: American Meteorological Society
Abstract: Recently reported results indicate that limited-area mesoscale models with prescribed lateral boundaries do not exhibit the same predictability error growth as observed in large-scale (global) models. These results have ...
Scale Interactions and Atmospheric Predictability: An Updated Perspective
Publisher: American Meteorological Society
Abstract: An examination of the scale interactions in predictability experiments is made using the NCAR Community Climate Model Version 3 (CCM3) at various horizontal resolutions ranging from T42 to T170. Both identical-model and ...
The Reliability of Improvements in Deterministic Short-Range Forecasts in the Presence of Initial State and Modeling Deficiencies
Publisher: American Meteorological Society
Abstract: The reliability of reductions of forecasting error derived from changes in the quality of the initial data or model formulation is considered using a signal-to-noise analysis. Defining the initial data error as the data ...
Dynamical Seasonal Prediction
Publisher: American Meteorological Society
Abstract: Dynamical Seasonal Prediction (DSP) is an informally coordinated multi-institution research project to investigate the predictability of seasonal mean atmospheric circulation and rainfall. The basic idea is to test the ...
