Evaluation of the new ECMWF WAM model

During the last years the European Centre for MediumRange Weather Forecasts (ECMWF) released new editions of the wave model WAM. The latest model version has been evaluated on both wave height and spectrum in close and shallow seas as well as in open oceans. The purpose of this work is twofold: First to discuss some evaluation results concerning the model performance and secondly to study the s...

Application of a serial extended forecast experiment using the ECMWF model to interpret the predictive skill of tropical intraseasonal variability

The extended-range forecast skill of the ECMWF operational forecast model is evaluated during tropical intraseasonal oscillation (ISO) events in the IndoWest Pacific warm pool. The experiment consists of ensemble extended serial forecasts including winter and summer ISO cases. The forecasts are compared with the ERA-40 analyses. The analysis focuses on understanding the origin of forecast error...

Path Forecast Evaluation

A forecast path refers to the vector of forecasts over the next 1 to h periods into the future. These forecasts are correlated across horizons so that to properly understand the uncertainty associated with the forecast path, one requires the joint predictive density of the path rather than the collection of marginal predictive densities for each horizon. This paper derives the joint predictive ...
