QBO Invesigation

Staying on the topic of the QBO, I decided to look back at all years since 1979 that had a September 30mb QBO number within 5.00 of our monthly anomaly this september (21.36). These years also had to fall within 2 months of the westerly QBO peak. Keep in mind that all these years were in the westerly shear phase going into winter, which is where we are headed currently. Here is the corresponding 500mb pattern for the following Dec-Feb periods.
