In Experiment FB (top-left panel), TT is generally lower by 0.2–0.8 °C throughout the tropics, except for the strong localized warmings off the Central America and Baja California and the weak warming in the southeastern Pacific. In the regional experiments, locally-generated δTδT’s tend PR-171 cell line to be dominated by negative signals because T0zzT0zz tends to be negative above the pycnocline (Section 3.2.2; Fig. 4b). As discussed above, the locally-generated signals converge to the equator and propagate eastward along it. In the eastern-equatorial Pacific (EEPO), the

pycnocline rises near the surface so that upper-pycnocline water impacts TT there. Therefore, the part of the remotely-generated signals that impact δTδT in the EEPO are those that lie on the upper pycnocline. As a single measure of the impact of δκbδκb in the EEPO, we use δTδT averaged over the Niño-3 region ( δTN3;150°W– 90°W,5°S– 5°N). For solution FB, δTN3=-0.35°C. Individual contributions of the regional solutions to equatorial δTδT differ considerably, owing to the different, local, background

temperature and salinity selleck kinase inhibitor structures that generate them and their different ways of propagation. The largest contributions to negative δTN3δTN3 come from Solutions ESE and ENE (bottom and upper-middle right panels of Fig. 9), a consequence of their forcing regions having the largest overlap with the Niño-3 region. Interestingly, negative contributions from Solution EQE and EQW are much smaller, because the locally forced negative anomaly is balanced by the underlying, positive one that rises into the upper 50 m there (Fig. 8b). The contributions from Solutions ESW and ENW (bottom and upper-middle left panels of Fig. 9) are small because their near-surface, negative dynamical signals do not much propagate

to the eastern equatorial Pacific, and their positive dynamical signals partially cancel their negative spiciness signals (right panels of Fig. B.3b and Fig. B.4b). In Solutions NE (top-right panel of Fig. 9) and NW (not shown), there is a systematic warming   of TT in the EEPO, a consequence of the dynamical, warming signal rising to the surface there ( Fig. 7b and Fig. B.2b). In contrast, in Solutions SE and SW (not shown) δTδT in the EEPO is weak because C-X-C chemokine receptor type 7 (CXCR-7) their positive dynamical signal is balanced by a strong negative spiciness signal ( Fig. 6b and Fig. B.1b). The contribution from Solution SE is weakly negative because the negative spiciness signal dominates, and that from SW is weakly positive because the spiciness is somewhat weaker and dynamical signal is somewhat stronger ( Appendix B.1). It was surprising to us that the contributions to equatorial TT differ so much among the regional solutions, and that altogether they tend to cool, rather than warm, TT in the EEPO.
