If any of that feels uneasy, consider some linear transformation, like a 90 degree counter clockwise rotation.

如果你觉得不舒服 可以考虑一些线性变换 比如逆时针旋转90度。

Hurricanes have both a counter clockwise rotation at one level, we call this cyclonic spin and at another level they have a clockwise rotation, known as anti-cyclonic spin.

飓风既在一个层面上是逆时针旋转的，我们称之为气旋旋转，同时在另一个层面上，它又是顺时针旋转，称为反气旋旋转。
