The divergence between the ECWAM ensemble members with respect to ocean waves is, therefore, due only to different wind forcing.  This can be attributable only to the coupled atmospheric ensemble members evolving in different ways, and indeed starting out from T+0 with (slightly) different fields of 10m winds (and other atmospheric parameters).   The ECWAM ensemble wavegram provides a probabilistic interpretation of the ECWAM ensemble for specific locations.  It displays the time evolution of the distribution of several marine parameters from the ECWAM ensemble at each forecast range by a box and whisker plot and information on wind and wave movement by a polar diagram (See Fig8.1.5-2).
