A model i.tercompari.on i. terms of surface ai. temperature annual cycle ampli.ude-phase characteri.ti.s (SAT AC APC) i. performed. The models i.cluded i. the i.tercompari.on belong to two groups: fi.e atmospheri. models wi.h prescri.ed sea surface temperature and sea i.e cover and four coupled models forced by the atmospheri. abundances of anthropogeni. consti.uents (i. total si. coupled model si.ulati.ns). Over land, the models, si.ulati.g hi.her than observed ti.e averaged SAT, also tend to si.ulate smaller than observed ampli.ude of i.s annual and semi.nnual harmoni.s and (outsi.e the Tropi.s) later-than-observed spri.g and autumn moments. The models wi.h larger (smaller) ti.e averaged ampli.udes of annual and semi.nnual harmoni.s also tend to si.ulate larger (smaller) i.terannual standard devi.ti.ns. Over the oceans, the coupled models wi.h larger i.terannual standard devi.ti.ns of annual mean SAT tend to si.ulate larger i.terannual standard devi.ti.ns of both annual and semi.nnual SAT harmoni.s ampli.udes. Most model errors are located i. the belts 60°–70°N and 60°–70°S and over Antarcti.a. These errors are larger for those coupled models whi.h do not employ dynami.al modules for sea i.e. No systemati. di.ferences are found i. the si.ulated ti.e averaged fi.lds of the surface ai. temperature annual cycle characteri.ti.s for atmospheri. models on one hand and for the coupled models on the other. But the coupled models generally si.ulate i.terannual vari.bi.i.y of SAT AC APC better than the atmospheri. models (whi.h tend to underesti.ate i.). For the coupled models, the results are not very sensi.i.e to the choi.e of the parti.ular scenari. of anthropogeni. forci.g.
