We use several variants of the detrended fluctuation analysis to study the appearance of long-term persistence in temperature records, obtained at 95 stations all over the globe. Our results basically confirm earlier studies. We find that the persistence, characterized by the correlation C(s) of temperature variations separated by s days, decays for large s as a power law, C(s) approximately s(-gamma). For continental stations, including stations along the coastlines, we find that gamma is… Expand

Power-law persistence in the atmosphere and in the oceans
The persistence of the weather is a well-known phenomenon. If, for example, one day is sunny and warm, there is a high tendency that the next day remains similar. In this paper, we review recentExpand
We re-analyze historical daily atmospheric temperature time series for investigating long-range correlation. Such a problem is attracting much attention due to the deep importance of assessingExpand
Long‐term memory in 1000‐year simulated temperature records
[1] We study the appearance of long-term persistence in temperature records, obtained from the global coupled general circulation model ECHO-G for two runs, using detrended fluctuation analysis. TheExpand
Extreme value statistics in records with long-term persistence.
It is found numerically that the integrated distribution function of the maxima converges to a Gumbel distribution for large R similar to uncorrelated signals, and that conditional mean maxima and conditional maxima distributions should be considered for an improved extreme event prediction. Expand
Long-term memory dynamics of continental and oceanic monthly temperatures in the recent 125 years
For both Northern and Southern hemispheres, the long-term memory dynamics for continent and ocean temperature records in the recent 125 years is studied in this paper. It is found that the recordsExpand
Climate persistence and memory
Abstract The autocorrelation function (ACF) and its relationship to fluctuation analysis (FA) are discussed, based on the reanalysis monthly mean geopotential height at 500 hPa from ECMWF (ERA-20C).Expand

Solar flare intermittency and the earth's temperature anomalies.
It is argued that Earth's short-term temperature anomalies and the solar flare intermittency are linked and the presence of a Lévy component in the temporal persistence of the temperature data sets that corresponds to the one that would be induced by the solar flares. Expand
