HRD seminar – Dr. Ray Bell, University of Reading, Reading, U.K. – 28 May 2014

Dr. Bell presented a seminar on “Dynamically simulated tropical cyclones in the high-resolution coupled climate model HiGEM: Their natural variability and response to climate change”

Abstract:

Due to recent advances in available computing resources, climate models can now be run with a high enough resolution to simulate different aspects of tropical cyclone activity. The El Niño Southern Oscillation (ENSO) has a large influence on tropical cyclone activity and is first investigated using a high-resolution coupled climate model (HiGEM). The results are shown with comparisons to an atmosphere-only version of the model (HiGAM) and observations. Subsequent model experiment are undertaken to investigate a contemporary issue on how different types of El Niño influence typhoon activity in the Western North Pacific. The final section investigates how tropical cyclone activity might change due to the influence of increased atmospheric carbon dioxide concentrations.
