On 12th October 2021, IFS cycle 47r3 was implemented, which included the new "Moist Physics" package, and as such, there have been changes in the characteristics of many forecast fields.
Further information on the impacts of 47r3 on surface weather representation is available on the Forecast User Portal at this link, including examination of a range of synoptic situations involving precipitation, and other variables.
