【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。更多还原

【Abstract】 With the establishment of radar network in the coastal area of China, radar measurements are becoming an important monitoring method for approaching typhoon especially before its landfall. An objective method to retrieve wind via tracing radar echo displacement is described in details and applied to the circulation and intensity estimation of landing typhoons “Nari" and “Chebi" in 2001. It is found that real wind distribution features can be captured effectively using CAPPI and PPI radar images by quality control with an accuracy equivalent to the operational analysis.更多还原
