-PNA corrosponding to NHEM TC formation?

[Juliancolton]

With the co-existence of TS Omeka in the CPAC and 95L in the Atlantic a while back, I started to wonder if there was a teleconnection potentially corresponding with the development of off-season TCs in the Northern Hemisphere, and I came across the PNA, which was in a fairly negative state at the time. Looking back over the past few months, it seems bursts of tropical activity in the EPAC and Atlantic basins tend to occur at the same time as negative dips in the PNA. I did some further sampling for the past several decades and my hypothesis has remained consistent so far. I've done quite a bit of research on the tendencies of the PNA, but it doesn't seem like there's much in the way of published material on the relationship, if any, between PNA swings and tropical cyclogenesis in the hemisphere. Has this been professionally covered at all?
