The difference of the accuracy of three interpolation methods for the aestival relative humidity was not significant.

对于三种插值方法，相对湿度的插值精度在夏季差异不明显。

In contrast, the aestival circulation shows the anticyclone pattern and its vertical structure has few changes in that season.

夏季流场比较复杂，总环流大致呈反气旋型，且垂向结构略有变化。
