摘要
本文从天气学角度分析青岛历史上两次极端高温过程的特点 ,发现青岛出现极端温度两次过程有共同的特性 :都发生在厄尔尼诺当年 ,都是大陆深厚暖高压控制 ;低空有强而持久的暖中心 ;高空为较强的下沉运动 ,有利于下沉增温 ;高低层相对湿度小 ,天气晴好 ,有利于太阳辐射地面增温 ;地面北风场 ,有利于大陆高温热风南袭。这些是促成高温过程的重要原因。
The characteristics of two extremely high temperature processes in Qingdao are analyzed from the synoptic viewpoint.It is found that there are many common characteristics between them: both occurred with El Nino; both were controlled by the warm continental high pressure; both had a strong and enduring warm center at tow altitudes; both had a downdraught at high levels which was benificial to subsidence and temperature increasing; both happened on sunny days which was helpful to ground temperature increasing by solar- radiation; and the surface north wind fields in both cases were benificial to the continental high temperature hot wind’s blowing southward. All the above mentioned are the important causes for high temperature processe formation.
