The session has established a regular interest from the scientific community, and attracted this year on average about 70 people to the Oral Programme. The session was presented by 8 oral (one cancellation) and 11 poster (3 no shows) papers. The overall ratio was excellent, almost 50% : 50%, but the contributions to the poster session were less than in previous years. The session considered all aspects of air-sea interaction: physics of fluxes (momentum, energy, heat, spray, moisture and gases) and processes (wind, waves, currents, slicks, rain, etc.) responsible for these fluxes at the air-sea interface, above and below; determination of fluxes from surface, aircraft and satellite; modelling studies at all scales. Theoretical talks were mainly devoted to the microscale air-sea interaction, with emphasis on the physics of air-sea interaction at high winds. Use of satellites for remote sensing of severe storms and detection of air-sea fluxes was discussed in several talks. Interesting talks considered numerical evidence for a reduced drag coefficient during a severe North Sea storm, and the need for high-resolution downscaling in extreme storm surge forecasts. As usual, observations of the momentum, heat and moisture fluxes on different scales were reported, and modelling of the air-sea interaction phenomena on regional scales was covered by the session.
