| 针对黔南州2022年4月24日午后到夜间的一次强对流天气过程，利用实况资料和都匀雷达ROSE2.0在短时强降水、冰雹、雷暴大风方面的监测和预警产品对比检验，结合本地短时临近预报业务应用效果分析,发现：受地形影响都匀雷达ROSE2.0估计降水在大雨以下量级表现较好，但对暴雨以上量级估计值偏小，没有明显短时强降水报警体现，本地化应用门限值降低约3成左右设置更为合理；都匀雷达ROSE2.0对冰雹预警落区指示和命中率较高，但时间提前量平均仅9分钟，对雷暴大风预警仍然有难度，剖面图分析能更好地识别雷暴大风指标。另外，雷达ROSE2.0软件强天气预警算法得到进一步优化，应融入一体化平台等快速支撑预警业务应用。 |

| Abstract: |
| In view of a severe convective weather process in Qiannan Buyei and Miao Autonomous Prefecture from noon to night on April 24,2022, the monitoring and early warning products of short-term heavy precipitation, hail and thunderstorm gale were compared with the real-time data and the uniform radar Rose2.0, combined with the analysis of the application effect of local short-term nowcasting operation, it is found that: under the influence of Topography, the estimated precipitation by the uniform radar Rose2.0 performs well in the order below heavy rain, but the estimated value above heavy rain is small, there is no obvious short-term strong precipitation warning, and it is more reasonable to lower the threshold value of localization application by about 30% . The uniform radar Rose2.0 has higher indication and hit rate of hail warning area, but the time lead is only 9 minutes on average, it is still difficult to forecast the thunderstorm and gale, and the analysis of the profile can better identify the thunderstorm and gale index. In addition, the strong weather early warning algorithm of radar Rose2.0 software has been further optimized and should be integrated into the rapid support early warning application platform. |
