“…During our sampling campaign the backwards air parcels trajectories were characterized a bimodal frequency distribution with a predominant Northeast and a secondary Southwest components (figure 5.5). We grouped the trajectories by selecting an arbitrary bounding box around our site and determined the corresponding cluster of each trajectory according to its bounding box crossing direction (Xia, Butorovic, and Yu, 2020).…”

Faculty of Forest Science and Forest EcologyBioclimatology Group Doctor of PhilosophyWater vapor, precipitation and evapotranspiration isotopic composition in the tropical atmospheric boundary layer by Mattia BONAZZA After 7 years it is really a challenge to remember all the people that interacted with me and in some way are involved in this project. So, hoping not to forget somebody (and, in such a case, I apologize beforehand), I would like to start remembering all the assistants, colleagues and professors that helped me to discover and carry out my research in Central Sulawesi, pak Dudin, Ibu Ilfi Anty, pak Alex, pak Ore and of course the professors of the Palu Tadulako University, Dr. Aiyen Tjoa, Dr. Henry Barus and Dr. Abdul Rauf. Without your support I couldn't even come to your beautiful country and carry out my research.Living in Palu for almost a year was not only a research experience but also a lesson of life. For this reason I cannot avoid to mention and thank all the friends that I have met during my stay in this beautiful corner of Indonesia, that are the Palu Vespa Club 777 and in particular Sapto Patrowo and friends (not forgetting the family that had the wonderful kiosk serving Saraba near the Hospital), who welcomed and included me (and later my wife) as part of a family in their Vespa club as an Italian guest driving an authentic old timer Vespa along the streets of Palu and throughout Central Sulawesi. Unfortunately I spent only a couple of weeks in Jambi and I didn't have the time to know all the Indonesian colleagues and partners of the EF-FORTS CRC 990 at the University of Jambi, however I thank all of them for the support and help during the measurements that I have carried out there.My deep gratitude goes for all the technical and non-technical staff of the Bioclimatology Group at the University of Göttingen, and especially to Edgar Tunsch and to Dr. Heiner Kreilein for sharing with me the frustration of carrying out a research in a beautiful, but sometimes too demanding, place like Indonesia. This gratitude is as well extended to the members of the technical staff of the Bioclimatology group, Frank Tiedmann and Dietmar Fellert, because your contribute is everywhere tangible and help us researchers in collect our data and finalize our research.In these years I had the privilege to work with a lot of smart and interesting scientists and students at the Bioclimatology Group. Not always our research goals crossed but, in any case, I thank all of you for sharing with me your working environment. In particular I would like to thank

This study has utilised National Oceanic and Atmospheric Administration (NOAA) NCEP/NCAR Reanalysis 1 project meteorological data and the HYSPLIT model to extract the air parcel trajectories for selected historical extreme rainfall events in South Africa. The k-means unsupervised machine learning algorithm has been used to cluster the resulting trajectories, and from this, the spatial origin of moisture for each of the rainfall events has been determined. It has been demonstrated that rainfall events on the east coast with moisture originating from the Indian Ocean have distinctly larger average maximum daily rainfall magnitudes (279 mm) compared to those that occur on the west coast with Atlantic Ocean influences (149 mm) and those events occurring in the central plateau (150 mm) where moisture has been continentally recirculated. Further, this study has suggested new metrics by which the HYSPLIT trajectories may be assessed and demonstrated the applicability of trajectory clustering in a region not previously studied. This insight may in future facilitate improved early warning systems based on monitoring of atmospheric systems, and an understanding of rainfall magnitudes and origins can be used to improve the prediction of design floods for infrastructure design.
