Case Studies of Satellite derived Cyclonic Rainfall over the North Atlantic: Algorithm- Model Intercomparison and In-Situ Validation
Satellite derived and ground validated data sets of rainfall and other important water cycle parameters during the passage of individual cyclones over the North Atlantic have been studied in detail to provide a deeper understanding of rainfall processes associated with frontal systems. The results h...
