Abstract The interannual and decadal variability of summer Arctic sea ice is analyzed, using the longest reconstruction (1850-2017) extent available, its relationship with dominant internal variabilities climate system further investigated quantitatively. leading empirical orthogonal function (EOF) mode captures an in-phase fluctuation over Basin. second characterizes a dipolar pattern out-of-p...

Abstract The warm Atlantic Water transported into the Barents Sea plays a crucial role in winter sea ice extent, marine ecosystems, and mid-latitude weather. North Oscillation is known to be an important driver for transport variability Opening. Here, we find that dependence of Opening ocean volume on non-stationary. Our results indicate period 1995 2005, link between temporarily weakened befor...

The consequences of climate change are becoming increasingly evident in the Tibetan Plateau, represented by glaciers retreating and lakes expanding, but the biological response to climate change by plateau-lake ecosystems is poorly known. In this study, we applied dendrochronology methods to develop a growth index chronology with otolith increment widths of Selincuo naked carp (Gymnocypris seli...

Abstract. This paper is devoted to the modeling of altitudedependent patterns of ozone variations over time. Umkehr ozone profiles (quarter of Umkehr layer) from 1978 to 2011 are investigated at two locations: Boulder (USA) and Arosa (Switzerland). The study consists of two statistical stages. First we approximate ozone profiles employing an appropriate basis. To capture primary modes of ozone ...

Recent evidences of the impact of persistent modes of regional climate variability, coupled with the intensification of human activities, have led hydrologists to study flood regime without applying the hypothesis of stationarity. In this study, a framework for flood frequency analysis is developed on the basis of a tool that enables us to address the modelling of non-stationary time series, na...

Climate variability and change significantly influences the health, prosperity, and well-being of individuals, societies, and the environment. For the United States this has been demonstrated, most recently, by several high impact events such as the 1997–98 El Niño event, the hurricane seasons of 2004 and 2005, the ongoing drought since 1999 in the Southwest, falling Great Lake levels, and the ...
