摘      要：The spatial patterns and regional-scale surface air temperature （SAT） changes during the last millennium,as well as the variability of the East Asian summer monsoon （EASM） were simulated with a low-resolution version of Flexible Global Ocean-Atmosphere-Land-Sea-ice （FGOALS-gl） *** model was driven by both natural and anthropogenic forcing *** features of the simulated past millennial Northern Hemisphere （NH） mean SAT variations,including the Medieval Climate Anomaly （MCA）,the Little Ice Age （LIA） and the 20th Century Warming （20CW）,were generally consistent with the *** simulated MCA showed a global cooling pattern with reference to the 1961-90 mean conditions,indicating the 20CW to be unprecedented over the last millennium in the *** LIA was characterized by pronounced coldness over the continental extratropical NH in both the reconstruction and the *** simulated global mean SAT difference between the MCA and LIA was 0.14°C,with enhanced warming over high-latitude NH continental *** between the simulation and the reconstruction on regional scales were lower than those on hemispheric *** major features agreed well between the simulated and reconstructed SAT variations over the Chinese domain,despite some inconsistency in details among different *** EASM circulation during the MCA was stronger than that during the LIA The corresponding rainfall anomalies exhibited excessive rainfall in the north but deficient rainfall in the *** the zonal and meridional thermal contrast were enhanced during the *** temperature anomaly pattern favored a stronger monsoon circulation.
