reduces with increasing latitude as the ITCZ reaches its maximum northerly extent. The most northern areas of Sudan receive virtually no rainfall. Wet season rainfall totals are highly variable from year-to-year due to large-scale dynamics in the climate system, such as the El Niño Southern Oscillation

so far.   At this point in the season, you’d expect 68% of winter’s average rainfall and sunshine. At the conclusion of January, both of these are at 69%, though there have been obvious fluctuations, as is normal in a UK winter.   So far, there has been 236.7mm of rain for the UK in winter, though

does not change the UKCP18 headline message of a greater chance of warmer, wetter winters and hotter, drier summers across the UK in future (Murphy et al, 2018). For 2061-80, under a high greenhouse gas emissions scenario (RCP8.5), the update suggests winters will be warmer by 3.3°C (2.0-3.5°C) 2

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

exceptionally wet and windy weather to the UK, particularly south Wales and south-west England. A few days later, the third named storm of the season, Storm Conall, brushed along the southern coast of England, bringing heavy rainfall. Although November started with mild temperatures, cold spells

about contingency measures. At the same time it will help them develop definite strategies for dealing with the more likely outcome of flooding seasons. Providing this type of probabilistic climate information requires a good understanding of the drivers of Asian monsoon and how they will change
