摘　　要：为了解决传统雷达反射率强度一致性分析与评估中数据展示不直观、分析方法不系统、分析效率较低等问题,提出一种基于空间数据的天气雷达反射率强度一致性分析新方法。通过空间数据库构建,获得雷达反射率强度平均偏差辐射图,并以广西及周边雷达为例开展了实例应用分析。结果表明,利用平均偏差辐射图可以直观地从宏观上评估多部雷达之间的反射率强度一致性关系,从而快速锁定可能存在问题的雷达,为台站开展整改提供重要参考,可有效用于雷达反射率强度一致性评估和雷达反射率强度一致性整改效果评估。To address issues such as non-intuitive data presentation,unsystematic analysis methods,and low analysis efficiency in traditional weather radar reflectivity intensity consistency analysis and evaluation,a novel method based on spatial data is proposed.This method involves constructing a spatial database to obtain average deviation radiation maps of radar reflectivity intensity.An empirical analysis is conducted using radars in Guangxi and its surrounding areas as examples.The results demonstrate that the average deviation radiation map can intuitively and macroscopically evaluate the reflectivity intensity consistency among multiple radars,enabling rapid identification of potentially problematic radars.This provides an important reference for stations to conduct rectification,effectively supporting both the assessment of radar reflectivity intensity consistency and the evaluation of rectification outcomes.
