This is a mathematical transformation where we create a sphere, and a set of points on this sphere correspond to vortex lines and their evolution over time.

涡量 Vorticity
（重定向自Vortex line）
涡量，也称为涡度，是一个流体力学的概念，用以描述流体的旋转情况。数学上，涡度
是描述速度场 
的旋度，是一个矢量场。
在气象学之中所考虑的流体就是大气，实务上通常就仅考虑涡度的铅直分量；另外，由于大气的速度场是以静止地球为参考坐标，故亦称为相对涡度。当气团的相对涡度为正值时，表示该气团出现逆时针转动；反之，相对涡度负值则为顺时针转动。
如果把地球转动都一并考虑的话，涡度就被称为绝对涡度；而绝对涡度与大气厚度的乘积一般而言为常数。

In continuum mechanics, the vorticity is a pseudovector field that describes the local spinning motion of a continuum near some point (the tendency of something to rotate ), as would be seen by an observer located at that point and traveling along with the flow.
