Master thesis

The understanding of factors associated with regional extreme climate events is a central step towards production better skillful prediction and more informed decisions in precipitation related disaster mitigation. This study contributes to new knowledge that can be helpful for future study. The findings can also help local authorities to enhance the monitoring and prediction skills of precipitation variability and thus can be applied in short-term to long-term adaptation strategies to mitigate losses due to precipitation-related disasters. 6.5 Suggestion for Future Research This work focused mainly on the use of statistical and diagnostic methods to achieve its objectives. Though the outcomes are satisfying, there are still some challenges that can be addressed for future research: 1) In-situ data or reanalysis data at higher spatial and temporal resolution can be employed to increase the accuracy and significance of the results. 2) More methods can be used in future works to confirm the significance and accuracy of the results obtained in the present study. 3) Scrutiny analyze in hand data, in order to define study domain, reading to suitable finding. 84

ACKNOWLEDGEMENTS First of all, I would like to extend my sincere gratitude to my thesis supervisor Professor Wang Jianhong. The scholarly advice, motivation and guidance she provided helped me through my study program and complete my Master thesis. I fully acknowledge her enormous contributions in this work. I wish also to express my sincere appreciation to IMSA and non-IMSA facilitators: Dr. Wido Hanggoro (Indonesia), MD. Jalal Uddin, Kabelo Lebohang Donald, Dr. Gnitou Tchalim Gnim (Togo), Dr. Asher Samuel Bhatti (Pakistan) and Peter Tuju (Tanzania). These facilitators have been a real blessing in my academic journey, with innumerable enlightening and inspiring practical class. They have also been a very big support in my personal life here in NUIST. I might not be able to list all the ways in which this family helped me but your role and all unmentioned contributions during my 2 years of Master studies will be forever remembered and appreciated. I would like to acknowledge my seniors and mentors who, since the very early stage of this work, provided constructive comments and advises; Dr. Wido Hanggoro (Indonesia), Dr. AYUGI Brian (Kenya), Lim Kam Sian Kenny Thiam Choy (Mauritius) and Brandon J. Bethel (Bahamas). I began this journey with all your support and the successful completion of this thesis is the evidence. Deepest appreciation to Brandon J.
