地面air temperature异常与太阳和地磁活动指数的统计关系
Statistical relationships between the surface air temperature anomalies and the solar and geomagnetic activity indices
摘要：
对1856 - 2000年全球和半球地面气温年距平资料进行了统计分析。全球和半球温度异常与太阳和地磁指数之间存在统计上的显著相关性。北半球和南半球的温度异常与太阳指数和地磁指数有相似的统计关系。互相关分析表明，全球温度滞后于太阳黑子和aa指数没有统计学意义。温度距平与地磁指数的相关性比与太阳指数的相关性高一倍左右。这些结果支持了地磁强迫对全球和半球表面气温的影响大于太阳活动强迫的观点。
英文摘要：
Statistical analysis of the data series from 1856 to 2000 for the annual global and hemispheric surface air temperature anomalies is completed. Statistically significant correlations are found between global and hemispheric temperature anomalies and solar and geomagnetic indices. The temperature anomalies in the Northern and Southern hemispheres show similar statistical relations with the solar and geomagnetic indices. The cross-correlation analysis shows no statistically significant global temperature lag behind the sunspots as well as behind aa-indices. The correlation between the temperature anomalies and the geomagnetic indices is about two times higher than the correlation between the temperature anomalies and the solar indices. These results support the suggestion that the geomagnetic forcing predominates over the solar activity forcing on the global and hemispheric surface air temperatures.
