Ocean Modelling, Data Assimilation and Forecasting
Timothy Williams Staff Picture

My main expertise is in applied mathematics, modelling water wave propagation in the presence of floating bodies (like ice sheets, for example). I have other interests in elasticity, wave propagation in random media, and mathematical techniques such as the Wiener-Hopf and residue calculus techniques. I am currently working on including the interactions between waves and sea ice in the MIZ (marginal ice zone) in a nested configuration of HYCOM (HYbrid Coordinate Ocean Model, nested inside an outer TOPAZ model) that has been set up in the Fram Strait.
