Hydro-Climatic Trends, Variability, and Regime Shifts

Increased aeolian activity during climatic regime shifts

Structural break models of climatic regime-shifts: claims and forecasts

A Chow test for structural breaks in the surface temperature series is used to investigate two common claims about global warming. Quirk (2009) proposed that the increase in Australian temperature from 1910 to the present was largely confined to a regime-shift in the Pacific Decadal Oscillation (PDO) between 1976 and 1979. The test finds a step change in both Australian and global temperature t...

Wavelet-Based Multifractal Analysis on Climatic Regime Shifts

A climatic regime shift is characterized by an abrupt transition from one quasi-steady climatic state to another. We attempted to explain the change of multifractal behavior of climate indices when a regime shift occurred. We used the wavelet transform method to analyze the multifractal behaviors of the El Niño/Southern Oscillation (ENSO) index (Niño3.4 index), Pacific Decadal Oscillation (PDO)...

Climatic warming and regime shifts in lake food webs—some comments

In a recent issue of Limnology and Oceanography, Schef-fer et al. (2001) argued that ''the probability of clear water phases increases with increasing lake water temperature in shallow lakes and that small decreases in temperature may create a shift to a turbid state and an increase to a clearwater state.'' They based their evidence on a correlation between a defined clearwater state and the wi...
