摘　　要：利用常规高空探测资料及地面观测资料,计算了表征大气稳定度、湿度和上升运动条件的物理量场,分析了2006年6月15-19日郑州地区持续35℃以上的高温天气,结果发现:新疆暖脊的发展和东北低涡的维持,利于郑州地区气温升高;对流层中下层湿度较小,且垂直分布为下干上湿,利于局地气温上升;大气层结稳定时,下沉运动会引起局地气温上升。By using the routine sounding data and surface observation data,we calculate some physical element fields,such as the index of atmospheric stability,the wet layer distribution,the conditions of vertical movement.Analyze the high temperature weather over 35 ℃ on 15-19 June 2006 in Zhengzhou.The results show that the development of Xinjiang warm ridge and maintenance of the Northeast vortex make increase in temperature in Zhengzhou.The humidity is smaller of the mesospheric and lower troposphere,and appears lower-layer dry and upper-layer wet in the vertical distribution.Those cause the local temperature to rise.When atmospheric layer is stable,subsidence movement causes the local temperature to rise.
