This work formed part of JS’s diploma thesis at the Freie Universität Berlin, Germany. Many thanks go to the Hurricane Research Division (HRD) and the Aircraft Operations Center (AOC) of the U.S. National Oceanic and Atmospheric Administration (NOAA) for obtaining the high-quality data and making it freely available. Without their data, the analysis of Hurricane Danielle and Isabel would have been impossible. Author JS also acknowledges the exchange scholarship of the DAAD (Deutscher Akademische Austauschdienst) and the Monash exchange scholarship that made nine incredible months at the Monash University, Melbourne, Australia possible and thanks the Bureau of Meteorology Research Centre (BMRC) for providing access to their computer facilities.
