摘　　要：Period and space distribution characteristics of high temperature (above 35 ℃) at 7 weather stations in Shenyang City from 1951 to 2008 were analyzed in this study.The results revealed that the occurrence period of high temperature in northern Shenyang was longer than the southern and eastern parts.The northwestern part had the most days of high temperature,the southeastern part came next,and the mid-eastern and southwestern parts had the least.The distribution characteristics of high temperature period were increasing frequency,enhanced intensity and expanded range after 1990s.The occurrence frequency of high temperature was the highest in June and the lowest in August.The hot late summer weather in the middle period of August in 2009 was caused by anomaly atmospheric circulation and subtropical high pressure (stronger and the more westward).Period and space distribution characteristics of high temperature (above 35 ℃) at 7 weather stations in Shenyang City from 1951 to 2008 were analyzed in this study.The results revealed that the occurrence period of high temperature in northern Shenyang was longer than the southern and eastern parts.The northwestern part had the most days of high temperature,the southeastern part came next,and the mid-eastern and southwestern parts had the least.The distribution characteristics of high temperature period were increasing frequency,enhanced intensity and expanded range after 1990s.The occurrence frequency of high temperature was the highest in June and the lowest in August.The hot late summer weather in the middle period of August in 2009 was caused by anomaly atmospheric circulation and subtropical high pressure (stronger and the more westward).
