  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

• Met Office explains: How is thunder formed?

  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

  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

• Early warnings fit for today and the future

  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

  ‘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

  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

• UK and Global extreme events – Heatwaves

  . On a regional scale, Europe, North America, Asia and Australasia have very likely (over 90% probability) observed an increase in heat extremes and decrease in cold extremes. Europe, Asia and Australia have also likely (over 66% probability) observed an increase in heatwaves. Due to less data

• Understanding convergence zones and the Intertropical Convergence Zone

  continue to converge, wet conditions can persist, sometimes resulting in significant rainfall totals and even flooding. Convergence lines are not limited to a particular season and can occur at any time of year. During the summer months, local sea breezes can help form convergence lines
