season in Nepal. Model evaluation criteria: How well do the climate models capture the large-scale processes in the atmosphere that cause extreme precipitation events? Model assessment criteria: In a south Asian monsoon, how well does the model capture wind speed and direction over the monsoon period

and August’s respective average temperatures were generally closer to average. However, despite above average temperatures for the season, it has also been a wetter than average summer, with July leading the way in terms of rainfall; which was provisionally the UK’s sixth wettest July on record

. December average temperatures 6 o C above the long-term mean in England from the Midlands southwards, and 5 o C above the long-term mean elsewhere. Average seasonal temperatures 3 o C above the long-term mean across the UK. Compound months and seasons November to April Wet (rainfall 2.5 times

‘Wet’ days: greater than the 1981-2010 90 th percentile daily precipitation ‘Windy’ days: greater than the 1981-2010 90 th percentile daily mean windspeed The thresholds are calculated separately by month and region, and the frequencies of exceedance averaged by nation and season. Based on UKCP18

but probabilities of a wetter season than last year and of 10-year extremes are presented. A wetter season than 2018 is favoured in most boxes east of 30E and between 10N and 10S. Elsewhere a drier season than 2018 is likely in most grid boxes. Probabilities of a season drier than any in the past 10 years (2009

events in Nepal Studying past extreme rainfall events in South Asia has highlighted the importance of the timing and location of monsoon rainfall. Extreme events often occur during years with high variability in monsoon rains, and not necessarily years with above average seasonal rainfall. Extreme

the implementation of the new service will be shared through workshops to benefit other developing countries across Southern Africa, supporting the WMO’s ambition of a global rollout of IbF. WCSSP Southeast Asia The damage and loss of life caused by severe weather in Southeast Asia is a significant barrier
