Update of ECMWF forecast system. A new version of ECMWF model (IFS cycle 47r1) was introduced at ECMWF. 

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.

The processing of the IFS reforecast (run in advance) has been suspended for the July's runs so that they would be computed from tomorrow by the new model version already.

Full details can be found in Implementation of IFS Cycle 47r1 page.
