Origins and impacts of spatial and temporal long-range dependence in the climate system
Fredriksen, Hege-Beate (Doctoral thesis; Doktorgradsavhandling, 2017-11-27)The internal variability of most Earth surface temperatures has a power spectral density well described by a power law, S(f) ~ f<sup>-β</sup>, and we typically observe 0 < β < 1. This characterizes variability exhibiting long-range dependence (LRD), which has no characteristic time scale. However, there is no consensus about the physical mechanisms behind this property, and the topic of this thesis ...
