‘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

time in order to reduce climate-related risks and support sustainable development for the coming season in sectors of critical socioeconomic significance. He cited South Asian Climate Outlook Forum (SASCOF) as an example of an RCOF. He added that the approach could be demonstrated in a few target

coast, but elsewhere in the UK, summer is typically the most thundery season. This variability means that maps showing thunderstorm frequency can differ depending on the period of record used. What causes lightning? Lightning is the precursor to thunder and forms within storm clouds through

The WMO’s Early Warnings for All initiative will ensure that every person on earth will be protected by early warning systems by early 2027. The Asia Regional Resilience to a Changing Climate (ARRCC) programme, supported by UK aid, aimed to help advance implementation of impact-based forecasting

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

characteristics of the East Asian Summer Monsoon compared to regional scale models, including the daily cycle of rainfall across many regions of China. Li et al (2019) focussed on an event in 2016 where 600mm of rainfall fell over parts of eastern China in just 6 days leading to catastrophic flooding

resilience of vulnerable communities around the world since 2014. Through the WCSSP programme, we are working collaboratively on projects that focus on the global challenges of weather and climate with partners in Brazil, China, India, South Africa and Southeast Asia. International collaboration

start of the MAM 2020 season. The sub-region will experience warmer than normal temperatures through the season. Noting that there was abundant rainfall during October – December 2019 and considering that the coming MAM 2020 rainfall season is anticipated to be wet, all stakeholders are called upon
