Institutions/Projects in the region working on S2S

S2S Southeast Asia Pilot Project: This project aims to explore the usefulness of S2S predictions for disaster risk reduction in Southeast Asia. Project partners include ASMC (https://asmc.asean.org/home/), the AHA Centre (https://ahacentre.org/), RIMES (https://www.rimes.int/), and UN ESCAP (https://www.unescap.org/). 

Research-to-operations for monsoon seasons in SE Asia: Subgroup under the Regional Working Group on Asian-Australian Monsoons (https://impo.tropmet.res.in/mpwg-aam-members.html). Topics include the role of intra-seasonal oscillations on monsoon onset. 

Weather and Climate Science for Service Partnership Southeast Asia: Launched in 2016, WCSSP Southeast Asia is a collaborative project that aims to develop and improve global and regional forecasting systems and advance the understanding of high-impact weather such as heavy rainfall events and tropical cyclones in Southeast Asia.  The WCSSP Southeast Asia project is part of our Weather and Climate Science for Service Partnership (WCSSP) programme, supported by the UK Government’s Newton Fund.  WCSSP Southeast Asia is a regional project with equitable collaborations between the UK and the Philippines, Malaysia, Indonesia and Vietnam. The lead organizations in each country are: The UK Met Office; The Philippine Atmospheric, Geophysical and Astronomical Services Administration ; The National Disaster Management Agency in Malaysia; Badan Meteorologi Klimatologi dan Geofisika in Indonesia; The Vietnam Meteorological and Hydrological Administration. Other partners include the National Centre for Atmospheric Science, University College London, University of East Anglia, University of Leeds and the University of Reading, in the UK, and Met Malaysia and Malaysian Industry-Government Group for High Technology (MIGHT), in Malaysia.

Key regionally-relevant S2S research questions & activities being pursued in the region

How best to use S2S forecasts for disaster preparedness?

How does the Madden-Julian Oscillation influences high impact weather events in Southeast Asia?
