Zusammenfassung der Projektergebnisse

Idealized numerical experiments were carried out to obtain a better understanding of the structure (especially the vortical structure) and evolution of rotating deep convection in tropical lows and tropical cyclones. Further experiments investigating the fundamental role of rotating deep convection in tropical cyclogenesis and tropical cyclone intensification have been carried out also and provide an important first step for future studies. A spin off of our involvement in the PREDICT experiment led to analyses examining the convective environment of tropical depressions based on an analysis of observations as well as a study of the boundary-layer thermodynamics in a mature hurricane.
