| 摘 要： | 应用巴中地区218个自动气象观测站2016年6～8月逐日的24h累积雨量，采取基于客观统计的检验方法，针对24h累积雨量，采取TS评分、BIAS评分和空报率对比分析了 SWCWARMS 模式和 EC 细网格模式在巴中地区的预报能力。研究结果表明:(1)从降水落区来看，两个模式都对雨带的移动都有较好的预报能力；(2)从降水 TS 评分看，SWCWARMS模式在各量级上的 TS 评分都优于 EC 模式；(3)从降水 BIAS 评分看，EC 模式容易漏报中雨及以上量级的降水，而 SWCWARMS 模式则对大暴雨的预报有较大的空报；(4)从逐月评估结果看，6月和7月SWCWARMS 模式较EC模式有更好的预报效果，8月两者差异不大。总体而言，SWCWARMS 模式在巴中地区的预报效果优于 EC 模式。

| Abstract: | Using the 24-hour cumulative rainfall of 218 automatic meteorological observatories in Bazhong from June to August of 2016, based on objective statistical methods, the prediction ability of the precipitation in Bazhong in 2016 of SWCWARMS model and EC model were evaluated and compared. The results show that: (1) Both of the SWCWARMS and EC model have good prediction ability for the rain band movement; (2) The TS score of SWCWARMS model has better performance than that of the EC model in all scales; (3) The EC model has larger omission rate in moderate to heavy rain forecast, while the SWCWARMS model has higher empty rate in heavy rain forecast; (4) The TS score of SWCWARMS model has better forecast ability than EC model in June and July. The SWCWARMS model is superior than EC model in the prediction of Bazhong area. |
