摘要
统计分析1960—2019年东亚夏季风与三明地区当年和次年前汛期降水,探讨东亚夏季风对三明地区前汛期降水的可能影响。结果表明:东亚夏季风同三明地区次年前汛期降水呈显著正相关;强(弱)夏季风使得次年三明地区前汛期降水偏多(少),主要是三明东部(西部)前汛期降水偏多(少);夏季风偏强时,次年前汛期副高西伸脊点偏西,三明地区多雨;夏季风偏弱时,次年前汛期副热带高压西伸脊点偏东,三明少雨。
The East Asian summer monsoon(EASM)and the precipitation in the first flood season of the same year and the second year in Sanming region during 1960-2019 were statistically analyzed to explore the possible influence of EASM on the precipitation in the first flood season in Sanming region.The results show that there is a significant positive correlation between the East Asian summer monsoon and the precipitation in the second flood season in Sanming region.The strong(weak)summer monsoon caused more(less)precipitation in the first flood season of the next year in Sanming region,mainly in the east(west)of Sanming region.When the summer wind is stronger,the western ridge point of the subtropical high in the second flood season is westward,and it is rainy in Sanming area.When the summer wind is weak,the west extension ridge point of the subtropical high in the second flood season is eastward,and there is little rain in Sanming.
