The featured image overlaps with a work in progress that is in peer review. It covers the classic Auto Regression Moving Average (ARMA) approach applied to the Sun, a parameter of the western tropical Pacific Ocean, and several rivers of the Southwestern US. I use this figure in part to explain much of the relatively high performance of our solar based hydrologic forecasts in the Southern Rocky Mountains.
legend description: ACF is Auto Correlation Function
5yta is the five year trailing average, typically derived from monthly average products.
SSN = Sunspot numbers
TWWP = a parameter of the atmosphere over the Western Equatorial Pacific
PnP, Animas, GnG, LFRUT = Streams of the Rocky Mountains, Western US
These patterns appear to be consistent with what I’ve termed the persistence of the Solar Mountain. Once again but through a different profile, the Sun’s auto correlation pattern is central to a persistent division between streams of the Rocky Mountains as this image samples from.
A better understanding of the cross regressions between all of these featured variables is also a focus of the paper in review.
