| 摘要: |
| 本文利用常规气象观测资料，对2013—2022年达州极端短时强降水特征和物理量指标进行了分析，结果表明：达州极端短时强降水峰值出现在8月，凌晨到早上是极端短时强降水的易发时段；极端短时强降水总体呈南部多、中北部少的特征；极端短时强降水年极值的天气学类型分为高空低槽型和副高控制型2种；极端短时强降水的相关物理量指标有利于达州进一步开展本地极端短时强降水潜势预报。 |

| Abstract: |
| This article analyzes the characteristics and physical indicators of extreme short-term heavy precipitation in Dazhou from 2013 to 2022 using conventional meteorological observation data, The results indicate that: The peak of extreme short-term heavy precipitation in Dazhou occurs in August, and the period from early morning to early morning is the prone period for extreme short-term heavy precipitation; The overall trend of extreme short-term heavy precipitation is characterized by more in the south and less in the central north; The synoptic types of extreme short-term strong precipitation annual extremes can be divided into two types: high-altitude trough type and subtropical high controlled type; The physical indicators related to extreme short-term heavy precipitation are conducive to further developing local extreme short-term heavy precipitation potential prediction in Dazhou. |
