AbstractAn自动大气河流（ARs）检测算法用于北大西洋盆地，该算法允许识别和全面表征1948-2012年期间影响伊比利亚半岛的主要AR事件。详细分析了伊比利亚半岛的极端降水日数及其与ARs发生的关系。极端降水日数按其大小排序，并在考虑1）受影响的面积和2）降水强度后获得。整个伊比利亚半岛、葡萄牙和伊比利亚六大流域（米尼奥、杜埃罗、塔霍河、瓜迪亚纳河、瓜达尔基维尔河和埃布罗河）在1950-2008年间的排名各不相同。结果表明，在西部地区（葡萄牙，米尼奥，塔霍河和杜埃罗）的AR和极端降水日数之间的关联是值得注意的，而东部和南部盆地（埃布罗，瓜迪亚纳和瓜达尔基维尔）的AR的影响是减少。
AbstractAn automated atmospheric rivers (ARs) detection algorithm is used for the North Atlantic Ocean basin that allows the identification and a comprehensive characterization of the major AR events that affected the Iberian Peninsula over the 1948–2012 period. The extreme precipitation days in the Iberian Peninsula and their association (or not) with the occurrence of ARs is analyzed in detail. The extreme precipitation days are ranked by their magnitude and are obtained after considering 1) the area affected and 2) the precipitation intensity. Different rankings are presented for the entire Iberian Peninsula, for Portugal, and for the six largest Iberian river basins (Minho, Duero, Tagus, Guadiana, Guadalquivir, and Ebro) covering the 1950–2008 period. Results show that the association between ARs and extreme precipitation days in the western domains (Portugal, Minho, Tagus, and Duero) is noteworthy, while for the eastern and southern basins (Ebro, Guadiana, and Guadalquivir) the impact of ARs is reduc...
