A simplified objective method to identify cluster climate event is proposed in this study and used for examining the cluster high temperature events occurred from 1961 to 2012.The identified results are consistent with the actual facts, implying the method with advantages of clear physical concept, simple operability and broad applicability is objective and effective.It is found that intensity of cluster high temperature events occurred after 2000 is the most significant among five decades either from the point of view of occurrence frequency, duration, affected stations or composite strength, which is in accord with the global warming background.Furthermore, the scatter distribution of cluster high temperature event averaged centers is featured with regional characteristics: the highest frequency is located the area south to Yangtze River, followed by the lower reaches of Yellow River in North China, and Xinjiang province is also frequent area.The annual frequency difference of cluster high temperature events in different areas can well reflects the impacts of the monsoon rains shift in China and the underlying surface.
