Tropical Pacific interactions in the WCRP‐CMIP3 multi‐model dataset

摘要: The ability of numerical models in reproducing the observed statistical links between sea surface temperature central and eastern tropical Pacific Ocean is analysed this paper. Significant whole spectrum frequency were studied for World Climate Research Program (WCRP-CMIP3/IPCC-AR4) using methodology wavelet coherence. During second half twentieth century, in-phase or quasi-in-phase oscillations 2–6 years, a lack relation 8–12 years time lagged longest periodicities are detected dataset. Some able to reproduce relationships shorter than 6 few them also lacks significant band years. On other hand, all have serious problems representing waves. The analysis shows that climate still unable specific features interactions with potential effect on Southern Hemisphere atmospheric circulation and, particular, South American climatic variability.
