中文摘要: 随着我国沿海雷达网的建设,雷达资料正逐步成为沿海气象台站台风临近登陆时的一 个重要监测手段。利用相关法雷达风场反演对2001年登陆台风“百合”和“飞燕”作了 环流和强度估测分析。 结果表明,通过适当的质量控制,该方法可以有效地反演得到台风 强风分布特征,分析精度与业务中常用的卫星估测方法相当。

Abstract:With the establishment of radar network in the coastal area of China, r adar measurements are becoming an important monitoring method for approaching ty phoon especially before its landfall. An objective method to retrieve wind via t racing radar echo displacement is described in details and applied to the circul ation and intensity estimation of landing typhoons “Nari" and “Chebi" i n 2001. It is found that real wind distribution features can be captured effectively usin g CAPPI and PPI radar images by quality control with an accuracy equivalent to t he operational analysis.
