| 摘 要： | 通过常规资料、新一代天气雷达、自动站等资料对2005年3月22日影响福建的一次飑线系统进行分析。分析指出，该飑线系统是由高空槽前型的上干下湿引起的不稳定强对流天气。对新一代天气雷达资料分析揭示了此次飑线的典型的弓状特征、强的后侧入流槽口以及入流槽口上的弱回波区等中小尺度结构特征是造成灾害性大风的成因。

| Abstract: | Based on the routine data and the observations of CINRAD/SA radar and automatic weather stations, a squall line affecting Fujian on May 22, 2005 is analyzed. The squall line is a kind of instable and strong convective weather caused by the air with upper-layer dry and lower-layer wet in front of the upper-troposphere trough. The Mesoscale structure, such as bow echo, strong rear inflow and weak echo region on the inflow entrance etc, with the squall line, caused the disasterous wind. |
