of annual indices have also been calculated and gridded. These were derived from daily temperature (T) or precipitation data using the following definitions: • Growing Season Length (GSL) = period (days) bounded by daily T_mean > 5 °C and < 5 °C (after 1 st July) for ≥ 6 days. • Heating Degree Days

The winter of 2020/21 overall has been wet and dull with near average temperature.

Interestingly we have seen the highest and lowest temperatures of the winter season in February. Cold conditions from the east brought low temperatures down to the lowest of -23.0°C at Braemar (Aberdeenshire) on 11 February followed by a southerly flow bringing warm weather from the Canaries

changes in the 21 st century are similar to UKCP09, with a move towards warmer, wetter winters and hotter, drier summers. However, natural variations mean that some cold winters, some dry winters, some cool summers and some wet summers will still occur. • The probabilistic projections show

patterns for May-September 2025-2029, relative to the 1991-2020 average, suggest anomalously wet conditions in the Sahel, northern Europe, Alaska and northern Siberia, and anomalously dry for this season over the Amazon. The Global Annual to Decadal Climate Update is issued annually by the World
