【摘要】:提出一種適用于我國(guó)不同季節(jié)、經(jīng)緯度和下墊面的機(jī)載氣象雷達(dá)強(qiáng)風(fēng)暴預(yù)警算法;诘鼗鞖饫走_(dá)數(shù)據(jù)建立機(jī)載氣象雷達(dá)探測(cè)強(qiáng)風(fēng)暴仿真模型。利用改進(jìn)的區(qū)域分割法和TITAN算法識(shí)別強(qiáng)風(fēng)暴單體及其特征參數(shù)。按經(jīng)緯度和下墊面將我國(guó)劃分為16個(gè)特征區(qū)域(含東海和南海),獲取這些區(qū)域冰雹強(qiáng)風(fēng)暴雷達(dá)特征參數(shù)閾值,并給出危險(xiǎn)天氣預(yù)警算法;诙鄠(gè)危險(xiǎn)天氣雷達(dá)實(shí)況數(shù)據(jù),進(jìn)行機(jī)載氣象雷達(dá)強(qiáng)風(fēng)暴天氣預(yù)警仿真實(shí)驗(yàn)。仿真實(shí)驗(yàn)結(jié)果表明,該算法有助于飛行員快速判定危險(xiǎn)天氣,保障飛行安全。
[Abstract]:A strong storm warning algorithm for airborne weather radar is proposed, which is suitable for different seasons, longitude, latitude and underlying surface in China. Based on ground-based weather radar data, a simulation model of airborne weather radar for strong storm detection is established. The improved region segmentation method and TITAN algorithm are used to identify the strong storm cell and its characteristic parameters. China is divided into 16 characteristic regions (including East China Sea and South China Sea) according to longitude and latitude and underlying surface. The threshold of radar characteristic parameters of hail storm in these regions is obtained, and a warning algorithm for dangerous weather is given. Based on the real data of several dangerous weather radar, the simulation experiment of airborne weather radar for severe storm weather warning is carried out. The simulation results show that the algorithm is helpful for pilots to quickly determine dangerous weather and ensure flight safety.
