Using Empirical Mode Decomposition To Study Periodicity And Trends In Extreme Precipitation, Noah Pfister
Using Empirical Mode Decomposition To Study Periodicity And Trends In Extreme Precipitation, Noah Pfister
Graduate College Dissertations and Theses
Classically, we look at annual maximum precipitation series from the perspective of extreme value statistics, which provides a useful statistical distribution, but does not allow much flexibility in the context of climate change. Such distributions are usually assumed to be static, or else require some assumed information about possible trends within the data. For this study, we treat the maximum rainfall series as sums of underlying signals, upon which we perform a decomposition technique, Empirical Mode Decomposition. This not only allows the study of non-linear trends in the data, but could give us some idea of the periodic forces that …
