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

. 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

. 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

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

increase is observed in tropical regions of South America, Northern Africa and through Asia. Similarly, the number of warm nights in these regions have increased by over eight days per decade, leading to a doubling since the late 1970s.  The variability of rainfall over space and time tends to be greater

. Shifting rainfall patterns will likely lead to some regions becoming wetter and others becoming drier. Additionally, these more arid regions could dry further because of global warming. Warmer temperatures can increase evaporation of water from the ground. As soils become drier, the air above may heat

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

features in the Caribbean. Results are presented for the early wet season (May–July) and late wet season (August– October). There is a relative insensitivity to domain size for simulating some important features of the regional circulation and key rainfall characteristics e.g. the Caribbean low level
