title08-03-2016 ECMWF forecast system change

Update of ECMWF forecast system. A new version of ECMWF model (IFS cycle 41r2) was introduced at ECMWF. 

The main consequences for ECMWF-S2S data are:
  • Introduction of a new model grid: the reduced Gaussian octahedral grid;
  • Horizontal resolution of the ENS increased from TL639 / N320 to TCO639 / O640 for ENS (Days 0 - 15) and from TL319 / N160 to TCO319 / O320  for ENS Extended (Days 16 - 46), where subscript C stands for cubic and O for octahedral;
  • For the medium-range ENS there will no longer be a decrease of resolution at day 10: the ENS Days 11 - 15 will be run at the same TCO639 / O640 resolution as ENS Days 0 - 10;
