2023年6月一次北部湾低压极端暴雨过程天气气候特征OA
Weather and climate characteristics of an extreme rainstorm process caused by a tropical depression in the Beibu Gulf in June,2023
利用逐日再分析资料,对2023年6月7-10日北部湾低压持续性极端暴雨过程的天气气候特征进行研究.结果表明,(1)持续性极端暴雨前期和期间,副热带高压异常偏北偏西,位置稳定.孟加拉湾—南海—菲律宾一带热带辐合带活跃,南海西部有低压系统生成,并移入北部湾.(2)季节内振荡(MJO)处在第2、3位相,受其东传影响,中高纬度环流形成的槽脊位置有利冷空气南下影响广西.中层500 hPa我国东北地区附近有东北低涡维持,低涡后部强盛偏北风引导冷空气南下,受偏…查看全部>>
The weather and climate characteristics of the persistent extreme rainstorm process of a depression in the Beibu Gulf from 7 to 10 June 2023 were studied using daily reanalysis data.The results show that:(1)the subtropical high was abnormally north-westerly and in a stable position during the pre-and period of the persistent extreme rainstorm.The tropical convergence zone along the Bay of Bengal-South China Sea-Philippines was active,and a low-pressure syste…查看全部>>
