Scope Western North Pacific Ocean and the neighbouring seas are among the world oceans where tropical cyclones (typhoons), both highest in number and intensity, are found. These typhoons impose direct threat to the half-billion people living near the Asian coasts. However, current typhoon intensity forecast skill is still poor and one of the identified major reasons for such a discrepancy is the lack of understanding on the complex interactions between ocean and typhoons. These complex physical and biogeochemical interactions include processes such as the role ocean currents and mesoscale ocean eddied play in typhoon's intensification, accurate characterisation of air-sea momentum and energy exchange between cyclone and ocean under extreme typhoon (and supertyphoon) wind conditions, as well as interactions between typhoon, wave, sea spray, and ocean. In summer 2010, a large field campaign (Impact of Typhoon On Pacific, ITOP) comprising aircrafts, research vessels, in situ ocean observational platforms, and satellite observations, was conducted in the western North Pacific ocean to explore the above-mentioned complex issues. This session welcomes submissions from both observational and modelling efforts and is not limited to specific ocean basins. Submissions under the broad discipline of cyclone-ocean physical and biogeochemical interactions are also very welcomed.
