Background

Steven Chan is an American trained meteorologist with background in computer science and upper atmosphere physics. Originally from Hong Kong, he has lived in the US for over a decade, and moves to United Kingdom in 2011.

Apart from science, he has interests in history, political science, and Japanese culture/language.

Chan is based in the Met Office Hadley Centre.

Research

Research Interest/background:

Extreme events, climate dynamics, tropical meteorology, hydrological cycle, dynamical regional climate and mesoscale models

Current role in Newcastle:

Steven Chan is part of the CONVEX project - a joint project between Newcastle University, Met Office, University of Exeter. He works on intercomparing and understanding high resolution Met Office Unified Model simulations of UK precipitation extremes.
