Dr Muhammad Eeqmal HASSIM

Dr Muhammad Eeqmal HASSIM’s main research interests are on understanding regional climate variability, climate extremes and climate change for the Southeast Asia region. In particular, he focuses on what influences the properties and behaviour of tropical rainfall over Singapore and how such characteristics may change in the future. He previously identified eight weather regimes that characterise Singapore’s climate.

Dr Hassim was part of the team that delivered the Second National Climate Change Study for Singapore, in collaboration with the United Kingdom Meteorological Office (UK Met Office). He is currently part of the team working on the Third National Climate Change Study for Singapore. Dr Hassim has also collaborated in other projects with the Public Utilities Board (PUB) and the Tropical Marine Science Institute (TMSI) of the National University of Singapore (NUS), looking into various aspects of the local and regional climate. His expertise covers high-resolution mesoscale and regional climate modelling, analysis of ground-based radar observations, weather regimes and tropical weather systems.
