摘要： 为研究新旧气候态下蚌埠地区降水变化趋势及差异,基于蚌埠地区1981—2020年4个国家基本气象站逐日降水数据,分析新旧气候态年、季、月和汛期不同时间尺度下降水的差异变化。结果表明,气候态P2下,蚌埠年均降水量增加,且主要集中在夏季,年降水日数近乎持平,表现为春夏减少、秋冬增加,其中固镇降水量和降水日数同步增加;大部分月份各地区降水变化一致,如6月降水量大幅增加,降水日数减少,降水强度和极端降水事件明显增加;汛期小雨、中雨、大雨的降水量和降水日数减少,暴雨降水量和降水日数增加。

Abstract: To investigate the precipitation variation trends and differences between the new and old climate normals in Bengbu,this paper analyzes the differences and changes of precipitation at different time scales （annual,seasonal,monthly,and flood season） under the old and new climate normals based on the daily precipitation data from 4 national basic meteorological stations in Bengbu from 1981 to 2020. Findings reveal that under climate normal P2,the annual average precipitation in Bengbu increased,with the increase mainly concentrated in summer. The annual number of precipitation days remained nearly unchanged,characterized by a decrease in spring and summer and an increase in autumn and winter. Among them,both precipitation amount and precipitation days in Guzhen increased simultaneously. The precipitation changes in various regions were consistent in most months. For example,in June,precipitation increased significantly,while the number of precipitation days decreased,with a notable increase in precipitation intensity and extreme precipitation events. During the flood season,the precipitation amount and number of precipitation days of light rain,moderate rain,and heavy rain decreased,while those of rainstorms increased.

Key words: Bengbu City, new and old climate normals, precipitation regimes
