| 摘 要： | 对1951～2008年沈阳市7个观测站35℃以上高温时间和空间分布特点进行分析。结果表明,沈阳北部地区高温出现时段长于南部及东部;西北部高温日数最多,东南部其次,中东部及西南部较少。高温时间分布特点是进入20世纪90年代以后,高温天气有频率增加、强度增强、范围扩大趋势;6月份高温出现频率最高,8月份出现频率最低。2009年8月中旬出现高温伏旱天气是由大气环流异常、副热带高压异常偏强偏西引起的。

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