RISA Reduced-Gravity Isopycnal Ocean Model: Hindcasts of El Niño
Publisher: American Meteorological Society
Abstract: A global isopycnal ocean model is presented for the study of interannual to interdecadal variability in the global ocean. The model treats the primitive equations on a sphere with a generalized vertical coordinate. This ...
The Relationship between Ensemble Spread and Ensemble Mean Skill
Publisher: American Meteorological Society
Abstract: Statistical considerations suggest that 1) even for a perfect ensemble (one in which all sources of forecast error are sampled correctly) there need not be a high correlation between spread and skill, 2) the correlation ...
The Effect of the 1997/98 El Niño on Individual Large-Scale Weather Events
Publisher: American Meteorological Society
Abstract: Can an individual weather event be attributed to El Niño? This question is addressed quantitatively using ensembles of medium-range weather forecasts made with and without tropical sea surface temperature anomalies. The ...
The Use of a Modified Ebert–McBride Technique to Evaluate Mesoscale Model QPF as a Function of Convective System Morphology during IHOP 2002
Publisher: American Meteorological Society
Abstract: The Ebert?McBride technique (EMT) is an entity-oriented method useful for quantitative precipitation verification. The EMT was modified to optimize its ability to identify contiguous rain areas (CRAs) during the 2002 ...
The Developmental Testbed Center and its Winter Forecasting Experiment
Publisher: American Meteorological Society
Abstract: The Weather Research and Forecasting (WRF) Developmental Testbed Center (DTC) was formed to promote exchanges between the development and operational communities in the field of Numerical Weather Prediction (NWP). The WRF ...
