    "abstract": "We use several variants of the detrended fluctuation analysis to study the\nappearance of long-term persistence in temperature records, obtained at 95\nstations all over the globe. Our results basically confirm earlier studies. We\nfind that the persistence, characterized by the correlation C(s) of temperature\nvariations separated by s days, decays for large s as a power law, C(s) ~\ns^(-gamma). For continental stations, including stations along the coastlines,\nwe find that gamma is always close to 0.7. For stations on islands, we find\nthat gamma ranges between 0.3 and 0.7, with a maximum at gamma = 0.4. This is\nconsistent with earlier studies of the persistence in sea surface temperature\nrecords where gamma is close to 0.4. In all cases, the exponent gamma does not\ndepend on the distance of the stations to the continental coastlines. By\nvarying the degree of detrending in the fluctuation analysis we obtain also\ninformation about trends in the temperature records.",
