The importance heat maps now have superimposed land outlines. It looks like for the pressure based model there is a minor hotspot on Darwin as well as a few more NW of Australia, but there is a much bigger hotspot in the Midway-Hawaii region, though not as big as the Fiji hotspot. Has anybody looked into a Fiji-Hawaii teleconnection?
The the most influential hostspot for the temperature model is around the Galapagos, of the coast of Ecuador. Is that known to be significat in other respects?
