RISAn Evaluation with the Fourier Amplitude Sensitivity Test (FAST) of Which Land-Surface Parameters Are of Greatest Importance in Atmospheric Modeling
Publisher: American Meteorological Society
Abstract: Land-surface parameterizations based on a statistical-dynamical approach have been suggested recently to improve the representation of the surface forcing from heterogeneous land in atmospheric models. With this approach, ...
Sensitivity of Calibrated Week-2 Probabilistic Forecast Skill to Reforecast Sampling of the NCEP Global Ensemble Forecast System
Publisher: American Meteorological Society
Abstract: PC requires the reforecast-calibrated Global Ensemble Forecast System (GEFS) to support the production of their official 6?10- and 8?14-day temperature and precipitation forecasts. While a large sample size of forecast?observation ...
Skillful Wintertime North American Temperature Forecasts out to 4 Weeks Based on the State of ENSO and the MJO
Publisher: American Meteorological Society
Abstract: revious work has shown that the combined influence of El Niño?Southern Oscillation (ENSO) and the Madden?Julian oscillation (MJO) significantly impacts the wintertime circulation over North America for lead times up to at ...
Application of a Hybrid Statistical–Dynamical System to Seasonal Prediction of North American Temperature and Precipitation
Publisher: American Meteorological Society
Abstract: Recent research demonstrates that dynamical models sometimes fail to represent observed teleconnection patterns associated with predictable modes of climate variability. As a result, model forecast skill may be reduced. ...
