Teleconnections are defined by the American Meteorological Society as:
“1. A linkage between weather changes occurring in widely
separated regions of the globe. 2. A significant positive or negative
correlation in the fluctuations of a field at widely separated points.
Most commonly applied to variability on monthly and longer timescales,
the name refers to the fact that such correlations suggest that
information is propagating between the distant points through the
That is borrowed from the Dr. Roger Pielke, Sr. blog with weather in my bold. There is a difference between weather and climate which is time. In climate science a lot of weather teleconnections or oscillations are used under the assumption they are climate indicators while climate isn't all that well defined. A repetitive signal of an ~ 60 year period with about four confirmed cycles, that is about 240 years might qualify as a Climate Teleconnection. The problem though is all those trick other things that impact climate.
When I did the For All the BEST Fans post the intent was to show that Best land and the Global ocean SST have a strong correlation and that both have a strong correlation to the Indo-Pacific Warm Pool. That is not news, though the scaled BEST correlation might have been interesting.
What we may have with the Indo-Pacific Warm Pool is a weakly damped recovery response from the western Pacific depths of the Little Ice Age. But what drives it?
Just for the current modeling crazy, here is my contribution.
