Objective The transport and mixing occurring across the tropopause is a fundamental mechanism determining atmospheric and climate dynamics. Examples of phenomena affected by tropopause exchange include water vapour distribution (and thus weather patterns), greenhou se gases vertical distribution, ozone depletion, and fate of pollutants like airplanes exhausts. Many mathematical tools are available for extracting from wind datasets transport and mixing information, but when applied to the tropopause and compared with tracer profiles often provide conflicting answers. This is due to the fact that the tropopause is a complex, active interface, and hence each method only unveils one aspect. This project proposes to integrate several methods for studying the exchange event s occuring at the tropopause. The outcome of this approach will be used to explain tracer profile observed in tracer measurements of airborne missions.
