图7 6次降水过程lg Z滑动平均值与小时lg I的相关系数 (数字12代表参与滑动平均反射率因子均在降水时次内;11则代表去掉最后反射率因子并在最前面相应加入一组值进行滑动平均,依次类推)

Fig.7 Correlation coefficient between moving average value of lg Z and 1 hour lg I during 6 precipitation processes (The number 12 represents that the reflectivity factors participating in the moving average are with in the precipitation hour; and number 11 represents that the last reflectivity factor is removed and the one before the first values are added to the front for moving average, and so on)
