Prof. TAM Chi Yung Francis 譚志勇
Associate Professor
I am a climate dynamicist with broad interests including monsoons, tropical atmosphere-ocean coupling, subseasonal-to-seasonal prediction, land-use/land surface change impacts and global warming. I use Earth System models to study El Nino-Southern Oscillation, Indian Ocean Dipole, their predictability and climate influences, land and marine heat waves, and those run at convection-resolving resolutions for tropical cyclone, storm surge, severe rainstorm and air quality modelling/prediction for megacities.
