| 分析铜仁市短历时(3 h,6 h,12 h)暴雨频次和暴雨极值的时空分布，结果表明:梵净山东北侧的松桃县是短历时暴雨的高发区，市域内暴雨橙色及以上预警最佳发布时刻主要在夜间，比例为62.5%（万山）～100%（思南），暴雨黄色以上预警发布最优时刻主要也是在夜间，比例为53.6%（万山）～77.3%（思南）。3h和6h雨量初始达到暴雨标准的时刻大部分也是在夜间，比例分别为达到50%（万山）～95.2%（印江）和58.8%（玉屏）～77.1%（松桃），开展强降水“三个叫应”十分必要。通过个例分析，县域范围内的短历时暴雨依然具有分散性和跳跃性特点，值班值守和服务时要引起足够重视。 |

| Abstract: |
| spatial and temporal distribution of rainstorm frequency and extreme value of short duration (3 h,6 h,12 h) in Tonren city was analyzed. The results showed that songtao county, northeast of Fanjing Mountain, was the high occurrence area of short duration rainstorm, and the best time of rainstorm orange and above warning was mainly at night, with the proportion of 62.5% (Wanshan) ~ 100% (Sinan). The optimal time for issuing yellow rainstorm warnings or above was mainly at night, with 53.6% (Wanshan) ~ 77.3% (Sinan). Most of the time when 3h and 6h rainfall initially reached the rainstorm standard was also at night, and the proportion was 50% (Wanshan) ~ 95.2% (Yinjiang) and 58.8% (Yuping) ~ 77.1% (Songtao), respectively. Therefore, it is necessary to carry out the "three calls" of heavy precipitation. Through the case analysis, the short duration rainstorm in the county area still has the characteristics of dispersion and jump, and should be paid enough attention to when on duty and service. |
