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。

After six minutes, the bees began to congregate around the left bee robot, causing the fish robot and, as a result, the fish to swim in a counter clockwise direction.
六分钟后，蜜蜂开始聚集在左边的蜜蜂机器人周围，导致鱼机器人和鱼逆时针方向游动。
Linear algebra
E.g. if we rotate all of space 90 degrees counter clockwise, then I Hat lands on the coordinates zero one, and Jay hat lands on the coordinates negative one zero.
例如 如果我们将整个空间逆时针旋转90度 那么IHat落在坐标01上 JayHat落在坐标-10上。

Clockwise
Circular motion can occur in two possible directions. A clockwise (typically abbreviated as CW) motion is one that proceeds in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in Commonwealth English) anticlockwise (ACW), or (in North American English) counterclockwise (CCW). In a mathematical sense, a circle defined parametrically in a positive Cartesian plane by the equations x = cos t and y = sin t is traced counterclockwise as t increases in value.
