Experience and Accomplishments
Pioneered in cloud modeling, with first one-dimensional model and first cumulus model on a computer. P.I. on cumulus modeling projects since early 1950's.
Led the work into multi-cloud modeling via observations of mergers and cloud interactions in lines.
Extensive experience in planning and leading observational experiments on convective cloud systems, such as the joint NOAA-Navy Project Stormfury, and the Florida Area Cumulus Experiment.
A leading participant in the aircraft aspects of several GARP experiments, particularly GATE, MONEX and TOGA/COARE
