The ECMWF forecast system IFS was upgraded to the version 48r1. With IFS Cycle 48r1, the horizontal resolution of the medium-range ensemble (ENS) will increase from 18 to 9 km. This will bring the ENS to the same horizontal resolution as the high resolution forecast (HRES). The vertical resolution for both ENS and HRES will remain at 137 model levels and the ENS will continue to have 51 members. For TIGGE, the IFS data is interpolated to the same resolution O640 as up to now.

The ECMWF forecast system IFS was upgraded to the version 47r3. Cycle upgrade 47r3 will bring improvements to the assimilation and observations usage and a significantly improved physical basis for moist processes, necessary to facilitate further development of the Integrated Forecasting System (IFS) and future application at convection-permitting resolutions.

The ECMWF forecast system IFS was upgraded to the version 47r1. This cycle includes changes in the treatment of observations and improvements in the data assimilation and to the model. Quintic vertical interpolation in the semi-Lagrangian advection scheme has been introduced as well as the inclusion of a better surface albedo climatology making use of more data from the MODIS instrument. New Metrics of Tropical Cyclone (TC) “size” will supplement the existing forecasts of TC track and intensity. Full details can be found in Implementation of IFS Cycle 47r1 page. |
