摘　　要：选取2016年8月辽东山区一次典型的高温天气过程,利用高空、地面气象观测资料对该过程的大气环流形势、物理量场以及地形影响因素进行分析。结果表明,在强大的副热带高压影响下,低层暖平流持续时间长、前期气温持续升高是本次高温天气的环流背景特点,背风坡气流下沉增温的叠加作用是高温出现的关键因素。A typical high temperature weather process of mountain area of eastern Liaoning Province in August 2016 was selected, using the high altitude and surface meteorological data, the atmospheric circulation situation, physical quantity field and terrain factors of this process were analyzed. Results showed that under the effects of strong subtropical high ,the circulation background characteristics of the high temperature weather process included long duration of low level warm advection and continuing rise of the temperature in early stage.A key factor causing the high temperature weather was the subsidence warming in lee slope.
