Most existing ensemble forecast verification statistics are influenced by the quality of not only the ensemble generation scheme, but also the forecast model and the analysis scheme. In this study, a new tool called perturbation versus error correlation analysis (PECA) is introduced that lessens the influence of the initial errors that affect the quality of(More)
Ocean prediction systems rely on an array of assumptions to optimize their data assimilation schemes. Many of these remain untested, especially at smaller scales, because sufficiently dense observations are very rare. A set of 295 drifters deployed in July 2012 in the north-eastern Gulf of Mexico provides a unique opportunity to test these systems down to(More)
NWP forecast performance has made great progress during the past decade due to a few important factors. First, the numerical forecast models at major numerical weather prediction (NWP) centres have improved tremendously due to more accurate physics parametrisation schemes and increased computing power, which permits the use of higher resolution forecast(More)
