Thanks Gavin.
That was interesting - especially the part about the winter before the solar min and the fact that this winter may not be the real solar min. You can see from the cycle graph that the Northern and Southern solar dynamos are out of phase - hence the double peak (one hemisphere peaks, then the other one does). The southern hemisphere of the sun is running behind the northern hemisphere so we won't reach true minimum until they both bottom - so next year rather than this year seems probable to me too.
When looking at analogues for the winter before minimum, what happens if you drop out the active cycles and only look at the weak cycles like 24 (probably not a lot of data unfortunately)? In the stronger cycle pre-min years, the sun spot count would typically be a lot higher than what we are seeing now. One thing that makes me think that we'll see a low solar analogue pattern this winter (even if next winter is the true bottom) is the pattern we saw emerge in late Feb/March last winter since that was possibly an early sign that the solar cycle was now favourable for blocking.
