Exploiting the Synergy of Remote Sensing Data to Analyse Convective Initiation Processes in Complex Terrain Andreas Behrendt, Sandip Pal, and Volker Wulfmeyer Institute of Physics and Meteorology, University of Hohenheim • Goals: • An exciting new data set awaits exploitation: the comprehensive, 4D, high-resolution remote sensing data of COPS • Address all CI science questions of COPS • Derive new synergetic data which are relevant to CI process studies at all Supersites • Evaluate and refine cumulus parameterisations in complex terrain with the observations Values of disposable parameters can be determined. The different approaches for the CI trigger function can be validated with high-resolution remote sensing data of temperature, humidity, wind, and clouds.
