Yeah, I wish I had the data at my fingertips but the best way I can describe it is a stratospheric tendency. If you've got a strong force teleconnection wise such a strong El Niño or strong La Niña, the QBO isn't going to change it. However it can be an additive force. A strong with a +qbo is just going to amplify the enso signal. If it's negative, the hope for blocking is much better. When the Qbo kept going positive my heart sank. Just another nail in the coffin. Next year we should be negative. Emphasis on "should".
