每日温度记录的去趋势波动分析：澳大利亚上空的地理依赖性
Detrended fluctuation analysis of daily temperature records: Geographic dependence over Australia
摘要：
用去趋势波动分析法分析了澳大利亚61个、匈牙利18个逐日气温距平记录。正的长程渐近相关延伸到5-10年，检测到每种情况下。与早先的说法相反，相关指数对大陆台站并不通用。有趣的是，主导因素是地理纬度在澳大利亚：总的趋势是减少相关指数与距离赤道的增加。这一趋势与Tsonis等人（1999）对北半球500百帕高度距平的研究结果完全一致。波动的方差表现出相反的趋势，离赤道越远，内在波动的幅度越大。在澳大利亚大陆东北边缘的三个观测站，对流层两年振荡的存在被清楚地确定。
英文摘要：
Daily temperature anomaly records are analyzed (61 for Australia, 18 for Hungary) by means of detrended fluctuation analysis. Positive long range asymptotic correlations extending up to 5-10 years are detected for each case. Contrary to earlier claims, the correlation exponent is not universal for continental stations. Interestingly, the dominant factor is geographic latitude over Australia: the general tendency is a decrease of correlation exponent with increasing distance from the equator. This tendency is in a complete agreement with the results found by Tsonis et al. (1999) for 500-hPa height anomalies in the northern hemisphere. The variance of fluctuations exhibits an opposite trend, the larger is the distance from the equator, the larger the amplitude of intrinsic fluctuations. The presence of Tropospheric Biennial Oscillation is clearly identified for three stations at the north-eastern edge of the Australian continent.
