这些结果可以很好地解释前面形态分析中的基本结论和实际观测事实。

In midlatitude, the ionospheric response to southward turnings in summer and equinox and by night is stronger, which fades out with latitude decreases. During the recovery phase the irregular fluctuation in the ionosphere comes forth. In low-latitude, the disturbance caused by the turnings is strong in summer and equinox and weak in winter, although it tends to be immersing into the background disturbances.

在中纬，发生在夏分季和夜间的翻转能造成较强的电离层负响应，其幅度随纬度的降低而变弱，在恢复过程中存在不规则振荡；在低纬，南向翻转引起的电离层响应在夏分季较强，在冬季则较弱，且易被淹没在电离层自身的扰动中。
