本文介绍了北大西洋涛动（NAO）对欧洲河流流量的影响的区域差异。的影响是确定的时间变化的强度的关系表示每月或季节NAO指数和排放量之间的相关系数记录在510个河流剖面。相关性分析结果采用Ward等级分组法进行排序。因此，获得的河流剖面的分类，有可能区分七个地区不同的性质之间的依赖性径流和强度的NAO。最显着的正相关性显示的河流芬诺斯坎迪亚，丹麦和西北部的不列颠群岛在冬季期间，而最显着的负相关性（也在冬季）记录的流的地中海盆地，法国西部和英格兰东南部。在东南部的波罗的海流域，流量与NAO指数显着的正相关性，可以观察到在冬季和春季的负相关性。
The article presents regional differences in the impact that the North Atlantic Oscillation (NAO) exerts on the flow of European rivers. The impact is determined by temporal variations in the strength of relations expressed by coefficients of correlation between monthly or seasonal NAO indices and discharges recorded at 510 river profiles. The results of the correlation analysis were arranged using Ward’s method of hierarchical grouping. The classification of river profiles thus obtained made it possible to distinguish seven regions differing in the nature of the dependence between streamflow and the intensity of the NAO. The most statistically significant positive correlations are displayed by the rivers of Fennoscandia, Denmark and the northwest part of the British Isles in the winter period, while the most significant negative correlations (also in winter) are recorded for streams of the Mediterranean Basin, western France and the southeast of England. In the southeast part of the Baltic Sea drainage basin, significant positive correlations of streamflow with the NAO indices can be observed in the winter season and negative correlations are observed in spring.
