Chaotic signature of climate extremes

Understanding the dynamics of climate extremes is important in its prediction and modelling. In this study, linear trends in percentile, threshold, absolute, and duration-based temperature and precipitation extremes indicator were obtained from 1979 to 2012 using the ETCCDI data set. The pattern of...

Zusammenfassung:	Understanding the dynamics of climate extremes is important in its prediction and modelling. In this study, linear trends in percentile, threshold, absolute, and duration-based temperature and precipitation extremes indicator were obtained from 1979 to 2012 using the ETCCDI data set. The pattern of trend was compared with nonlinear measures (Entropy, Hurst exponent, recurrence quantification analysis) of temperature and precipitation. Regions which show positive trends in temperature-based extremes were found to be areas with low entropy and chaotic values. Complexity measures also revealed that the dynamics of the Southern Hemisphere differs from that of the Northern Hemisphere.
