@MichaelEMann Nice study. Might be interesting to look at decadal changes in coefficients of the AR(1) process. Crespo-Miguel et. al. fitted a recharge oscillator model to equatorial SSTs & WWV and found a decreasing damping rate of thermocline depth a
@WHUT @ggweather Study by Crespo-Miguel et al. also found that coupling between Pacific & Atlantic SSTs increased ~1970. From Fig 5, showing cross-correlation between Pacific & Atlantic SSTs vs. lag time. Note that study only goes through 2000 -- m
@WHUT @ggweather The equatorial Pacific discharges heat during an eastern Pacific El Nino, & absorbs heat during La Nina when cold waters upwell in the eastern Pacific. Study by Crespo-Miguel et al. showed coupling btwn Nino 3 temps & warm water vo
@LeonSimons8 @Willard1951 @RARohde @Lijing_Cheng It’s also possible that a more distinct recharge / discharge relationship is developing in the western boundary currents as the heat buried below 300m in the oceans discharges. It would be somehow analogous
