Mr Raizan RAHMAT

Mr Raizan Rahmat’s work in CCRS focuses on generating seasonal and subseasonal predictions for Singapore and the region, and improving their accuracy and usefulness. He is part of the team that works on producing long-term climate projections for Singapore to support its efforts in being resilient to climate change. Raizan also conducts research to better understand the key processes that drive extreme weather and climate locally and in the region.
