| Zusammenfassung |
| We present a near global statistics on the correlation properties of daily
temperature records. Data from terrestrial meteorological stations in the
Global Daily Climatology Network are analyzed by means of detrended
fluctuation analysis. Long-range temporal correlations extending up to
several years are detected for each station. In order to reveal nonlinearity,
we evaluated the magnitude of daily temperature changes (volatility) by the
same method. The results clearly indicate the presence of nonlinearities in
temperature time series, furthemore the geographic distribution of
correlation exponents exhibits well defined clustering. |
