利用地面自动气象站观测数据、多普勒雷达探空数据、FY卫星云图反演数据,对2008年6月5日发生在北部湾海域的一次海风锋触发形成的强对流天气进行了综合分析,归纳出本次北部湾海风锋系统活动的特征。结果表明,本次海风锋为一个中-β尺度对流系统,主要受偏南海风、偏北陆风和出海高压后部东风波动的共同影响而形成,锋面呈现东西两端,其中东段深入内陆约150km。
Using automatic weather station surface observations,Doppler radar sounding data,FY satellite image retrieval data on 5 June 2008 in the Beibu Gulf,the severe convective weather triggered by Sea Breeze Front(SBF)was comprehensively analyzed,the activity characteristics of Beibu Gulf SBF were also summarized.The results show that SBF as a mesoscale convective system,mainly due to the combined effect of southerly winds,the rear north easterly land breeze and the fluctuations of sea high pressure.In this process,SBF showed two parts,the east of which extended about 150km inland.
