Here is the latest image of the Upper Air polar circulation at 10 mb. The center of the larger CCW circulation is at 74 N / 71 E and the smaller CW circulation is at 62 N / 147 W. What I think is going to happen from now on is that the CCW system will slowly become smaller and the CW system will grow larger and eventually dominate as the summer season approaches. In the southern hemisphere, the opposite should take place.
