摘要:

利用1971 ~2010 年阿勒泰地区7 个观测站的逐日最高气温资料和同时期NCEP 再分析资料进行分析,总结出形成阿勒泰地区区域性高温天气的概念模型。并且对2004 年7 月12 ~ 18 日出现在阿勒泰地区的典型强高温天气过程进行分析,得出:阿勒泰地区持续的高温天气主要是100 hPa 环流背景长时间稳定维持;500 hPa 受伊朗高压或西太平洋副热带高压控制,或两者同时作用;850 hPa上24 ℃暖中心长时间存在,中心值一直增大;加上地理位置的优势,从而造成阿勒泰地区的持续性高温天气,并且极易形成极端高温天气。

Abstract:

By using observation data of 7 observation stations in Altay from 1971 to 2010,and combined with NCEP reanalysis data,the conceptual model of summer high temperature weather in Altay has been established. At the same time,the typical extremely high temperature process on July 12 - 18,2004 was analyzed. The results show that the 100 hPa circulation remained stable for long time resulted in high temperature weather,and the Iran high or the western Pacific subtropical high controled at the level of 500 hPa,or both at the same time effected on 500 hPa,and 24 ℃ warm center existed for a long time on 850 hPa,and the advantages of geographic location,these all caused the continuous high temperature weather in Altay and easy to form extremely hot weather.

Key words: summer high temperature;, conceptual model, subtropical high
