　　Two dominant modes of the winter temperature over East Asia, a northern mode and a southern mode, and their links with the Arctic climate conditions are analyzed.Their relationships with Arctic surface temperature are different, in which the northern mode is linked closely with anomalous warming of the Arctic Barents-Kara Sea in previous autumn and concurrent winter and the southern mode seems independent from the Arctic but is associated with sea surface temperature (SST) anomalies in the equatorial central-eastern Pacific.
