Summary of cycle 47r1

Implementation date	2020-07-13
Detailed description of changes	Implementation of IFS Cycle 47r1
Key characteristics of our forecasting system	Key characteristics of our forecasting system
Resolution	Horizontal (unchanged)	Vertical (unchanged)
Data set affected	HRES ENS Tropical cyclone track
Score card	The new model cycle brings improvements throughout the troposphere in the order of 0.5% in extra-tropical upper-air forecasts. The improvements are most apparent in the ENS scores, both against own analysis and against observations. Scorecards presenting the new cycle performance are regularly updated: HRES scorecard ENS scorecard
Meteorological changes	The changes in this model cycle cover the Data Assimilation, treatment of observations and improvements to the model itself
Meteorological impact	New metrics for Tropical cyclones Convective inhibition EFI Evaluation
Technical changes	GRIB encoding BUFR encoding Software
Model ID	Atmospheric: 151 Ocean wave: 116
New and changed parameters	HRES ENS Tropical Cyclone track
Discontinued disseminated model output	Not applicable
