Fig. 6: Comparison of the half-precession cycles in the western equatorial Pacific (WEP) sea surface temperature (SST) variations in the three simulations with the maximum equatorial insolation.
From: Forcing mechanisms of the half-precession cycle in the western equatorial Pacific temperature
a Insolation at the Equator: the purple (blue) line is March (September) insolation, the yellow dashed line is the maximum of them40. The gray line is eccentricity. b–d The filtered half-precession cycle (8–12 kyr) of SST in the Orb, OrbGHG and OrbGHGIce simulations, respectively. The vertical dashed lines indicate the peaks of the half-precession cycle of SST in the Orb simulation. e–g Cross-wavelet spectra between the SST of the three simulations and the maximum equatorial insolation.
