When you see a 200mb VP anomalies chart for the month of November. During a La nina. This is pretty much exactly what you would wish for.
The La Nina related MC forcing was mostly, not all, but mostly in the SH. But by South America (very difficult to do in la nina) it was not. It was more NH. So it appears to have dominated accordingly based on the upcoming pattern we're faced with. So for the lead in of any year, that's all you could ever ask for as far as I can tell. According to these charts anyway. Yes theres certainly other factors. A lot of the other factors aren't too shabby either. So hey, we'll see where it takes us.
