摘　　要：本文回顾了20世纪60年代至今国内外海风锋的雷达观测分析研究,概括分析了海风锋的雷达识别和演变特征,以及海风锋的三维结构。结果表明:海风锋的雷达观测分析研究已经在中国、美国、英国和保加利亚等地区开展,取得了不少研究成果;海风锋观测由早期的声雷达转为电磁雷达,最后转为如今的激光雷达;识别方法主要有特定波长降水粒子散射探测、局地风廓线探测和激光雷达探测3种;海风锋在低仰角(0.5°或1.5°)基本反射率产品上表现为强度较弱且平行于海岸移动缓慢的窄带回波。此外,本文还提出了一些值得进一步关注的问题。This paper reviews the analysis and research of sea breeze front radar observations in China and abroad in recent 60 years, and summarize the radar identification and evolution characteristics of sea breeze front as well as its three-dimensional structure of sea breeze front. The results show that the analysis and research of sea breeze front radar observations has been carried out in China, USA, UK and Bulgaria, and many research results have been achieved. Research on radar observation and analysis of sea breeze fronts has been carried out in China,USA, UK and Bulgaria, and many research results have been achieved. The ways of sea breeze front observation changed from acoustic radar to electromagnetic radar and finally to lidar at present. Since the 1960s, there have been three identification methods, which are precipitation particle scattering detection with specific wavelength,local wind profile detection, and lidar detection. The sea breeze front at low elevation angles(0.5° or 1.5°) of the fundamental reflectivity product shows a weak narrow-band echo moving slowly parallel to the coast. Finally,some problems worthy of further attention are raised in this paper.
