The ECMWF forecast system IFS was upgraded to the version 47r148r1. 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. 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.

UM upgraded to version PS43 for the 12UTC cycle on 4 December 2019. The PS43 upgrade to the Met Office global modelling capability introduces a new data assimilation system to the global ensemble and a significant upgrade to the global model physics. MOGREPS-G is now driven by an ensemble of analyses, each with its own data assimilation cycle (En-4D-en-VAR), replacing the original ETKF (Ensemble Transform Kalman Filter) method. The result is a more sophisticated ensemble with increased spread and stability. The global model physics is upgraded to the GA7.2 configuration which is focused on improvements to physical processes. This has several significant benefits including improvements to 250hPa winds, 850hPa tropical winds and temperatures and improved tracks of Tropical Cyclones. The UM is upgraded to UM11.2. |
