本文对地磁指数(AP)与大连日平均气温之间的逐日滑动相关系数进行了计算。发现相关系数随时间呈现正负相间的交替变化。选取其中较好的相关关系,对影响大连的冷空气过程进行了试报。
In this paper, daily slip correlation coefficients between geomagnetic index (AP) and daily average temperature in Dalian are calculated. Found that the correlation coefficient showed alternating positive and negative changes with time. Select the better correlation among them, and test the process of cold air that affects Dalian.
