Southern hemisphere stratosphere warmings occur in the winter over the polar region.
It is not unusual to have a patch of warming in the uppers and associated wave disturbances propagating down to the troposphere where most of us observe the weather.
Some years the disruption to the polar vortex is mild and the vortex may wobble from its symmetry.
This year, winter 2019. The polar vortex is forecast by GPS to split into two around the 10th of July. This event is not so common in the Southern hemisphere .
The repercussions are positive for the snow fields. Cold air and troughing is likely to be pushed northward into the mid latitudes generally about a week after the vortex splits
I see this event as a chance to learn more about the dynamics of the event but more importantly for you guys the effect on snow production.
So stay tuned..and would to hear your views or answer your questions
