From Discussion Session : Gas Exchange at High Wind Speeds : Recent Observations and Constraints
The discussion started with 4 brief presentations which provided a theoretical background for the ensuing discussion. The presentations are posted and thus not much detail on the presentations is included here. (1) Anna Rutgersson presented the basic air-side theory of gas exchange. She discussed how young waves are found under high wind speeds. In laboratory studies, the drag coefficient level...
متن کاملMeasurements of air-sea gas exchange at high wind speeds in the Southern Ocean: Implications for global parameterizations
[1] The SOLAS Air-Sea Gas Exchange (SAGE) Experiment was conducted in the western Pacific sector of the Southern Ocean. During SAGE, gas transfer velocities were determined using the He/SF6 dual gas tracer technique, and results were obtained at higher wind speeds (16.0 m s"1) than in previous open ocean dual tracer experiments. The results clearly reveal a quadratic relationship between wind s...
متن کاملDrag coefficient reduction at very high wind speeds
[1] The correct representation of the 10-m drag coefficient for momentum (K10) at extreme wind speeds is very important for modeling the development of tropical depressions and may also be relevant to the understanding of other intense marine meteorological phenomena. We present a unified boundary layer model for (K10), which takes account of both the wave field and spray production, and asympt...
متن کاملAn Estimate of the Geosat Altimeter Wind Speed Algorithm at High Wind Speeds
Existing wind speed algorithms for satellite altimeters have been developed from data in the range 0 to 20 m/s. At higher wind speeds the available algorithms diverge alarmingly. By comparing Geosat altimeter values of the radar cross section with model predictions of the surface winds during satellite overpasses of tropical cyclones, a wind speed algorithm valid for wind speeds between 20 and ...
متن کاملReply to comment by X. Zhang on ‘‘Measurements of air-sea gas exchange at high wind speeds in the Southern Ocean: Implications for global parameterizations’’
[1] We thank Zhang [2007] for recognizing the significance and importance of our work. In his comment, he questioned whether we have correctly assessed the wind speed/gas transfer velocity relationship derived from the NZ SOLAS Air-Sea Gas Exchange (SAGE) experiment [Ho et al., 2006]. Specifically, he assumes that we only analyzed the gas transfer velocity data from SAGE using a quadratic wind ...
