The daily maximum and minimum temperatures observed at the 1897 meteorological stations of China over the past 60 years (1951-2010) are analyzed in this study to examine the interdecadal variation of frequency for record-breaking event (RBE) of temperature in the context of global warming.The results indicate that the frequency of record-breaking high temperature in the first decade of the 21th century is the highest in the three decades from the 1980s to the 2000s, implying a distinct warming trend.Meanwhile, frequencies of record-breaking low temperature in the 1990s and the beginning of the 21th century are also significant.In particular, the RBEs of low temperature occurred over most of China in the 1990s but concentrated in northern China during the 2000s.To understand why the record-low temperatures in northern China are repeatedly broken in the 2000s, the related East Asian Winter Monsoon (EAWM) variability is investigated.
