【摘要】：自然天氣災(zāi)害對(duì)生活生產(chǎn)的影響十分巨大,因此如何準(zhǔn)確的對(duì)災(zāi)害天氣進(jìn)行預(yù)警已經(jīng)成為氣象管理部門的工作重點(diǎn)。但是在對(duì)災(zāi)害性天氣進(jìn)行預(yù)警時(shí),就需要多部雷達(dá)協(xié)同探測(cè),因此多部雷達(dá)的聯(lián)網(wǎng)探測(cè)以及圖像拼圖技術(shù)已經(jīng)成為制約災(zāi)害天氣預(yù)警能力發(fā)展的關(guān)鍵技術(shù)之一。本文在系統(tǒng)地研究分析雷達(dá)拼圖算法、技術(shù)和軟件工具的基礎(chǔ)上,針對(duì)目前新一代天氣雷達(dá)單純靠原圖拼接的問題,結(jié)合GIS技術(shù)研究了新一代天氣雷達(dá)產(chǎn)品拼合方法,設(shè)計(jì)開發(fā)了回波圖像拼合平臺(tái),該系統(tǒng)以貴州省地理信息系統(tǒng)為平臺(tái),實(shí)時(shí)疊加顯示雷達(dá)回波、雷電監(jiān)測(cè)信息等資料;實(shí)現(xiàn)了對(duì)該地區(qū)天氣,特別是雷電天氣的實(shí)時(shí)監(jiān)測(cè)。開發(fā)的系統(tǒng)通過對(duì)新一代天氣雷達(dá)產(chǎn)品數(shù)據(jù)文件、雷電監(jiān)測(cè)信息進(jìn)行了詳細(xì)的分析,實(shí)現(xiàn)了以圖形和文字的形式顯示數(shù)據(jù)文件內(nèi)容的功能,可以對(duì)一般的預(yù)報(bào)進(jìn)行指導(dǎo),幫助定位降雨或者暴雨天氣的出現(xiàn)地區(qū),在一定程度上提高天氣預(yù)報(bào)的準(zhǔn)確度。本文的主要工作和取得的成果主要包括:嘗試實(shí)現(xiàn)基于GIS的新一代天氣雷達(dá)數(shù)據(jù)可視化以及基于GIS的等值線繪制技術(shù)、雷電監(jiān)測(cè)數(shù)據(jù)顯示。實(shí)現(xiàn)了多部雷達(dá)聯(lián)網(wǎng)數(shù)據(jù)的拼圖管理,并且通過等值線提取、柵格圖的繪制以及文件管理等功能模塊,實(shí)現(xiàn)了對(duì)災(zāi)害性天氣發(fā)生區(qū)域的準(zhǔn)確鎖定,為氣象部門準(zhǔn)確的預(yù)測(cè)災(zāi)害性天氣發(fā)生的區(qū)域和時(shí)間提供了依據(jù)。
[Abstract]:The impact of natural weather disasters on daily life is very great, so how to accurately early warning disaster weather has become the focus of meteorological management departments. However, in the early warning of disastrous weather, many radars are needed to cooperate in detection, so the network detection and image mosaic technology of multiple radars have become one of the key technologies that restrict the development of early warning ability of disaster weather. Based on the systematic research and analysis of radar mosaic algorithms, techniques and software tools, this paper studies the new generation weather radar product assembly method based on GIS technology, aiming at the problem that the new generation weather radar simply depends on the original map stitching. The platform of echo image assembly is designed and developed. The platform is based on Guizhou Geographic Information system (GIS), which can display radar echo and lightning monitoring information in real time, and realize the real-time monitoring of the weather in this area, especially the lightning weather. Through the detailed analysis of the new generation weather radar product data file and lightning monitoring information, the system realizes the function of displaying the contents of the data file in the form of graphics and text, and can guide the general forecast. Help locate areas where rainfall or heavy rain occurs and improve the accuracy of weather forecasts to a certain extent. The main work and achievements of this paper are as follows: try to realize the new generation weather radar data visualization based on GIS, the isoline drawing technology based on GIS, and the lightning monitoring data display. Through isoline extraction, grid drawing, file management and other functional modules, it realizes the accurate locking of the disastrous weather area, and realizes the jigsaw management of several radar network data, and through the function modules of isoline extraction, grid map drawing and file management, it realizes the accurate locking of the disaster weather area. It provides the basis for the meteorological department to predict the region and time of the disastrous weather.
