使用每日雨量计数据分析了1950-2008年期间欧洲潮湿天气（随后出现大量降水）的持续时间和相关降水。在过去的60年里，欧洲大部分地区的湿润期延长了约15- 20%。潮湿期的延长并不是由于潮湿日数的增加。欧洲的湿润期变得更长，现在的特点是降水量更丰富。与1950年代和1960年代相比，过去20年的强降水事件越来越频繁地与较长的潮湿期联系在一起，并有所加强。降水时间特征分布的变化对较长的事件和较高的强度应该对陆地水文循环，包括地下水动力学，地表径流和欧洲洪水产生重大影响。
Analysis of the duration of wet spells (consequent days with significant precipitation) in Europe and associated precipitation is performed over the period 1950–2008 using daily rain gauge data. During the last 60 years wet periods have become longer over most of Europe by about 15–20%. The lengthening of wet periods was not caused by an increase of the total number of wet days. Becoming longer, wet periods in Europe are now characterized by more abundant precipitation. Heavy precipitation events during the last two decades have become much more frequently associated with longer wet spells and intensified in comparison with 1950s and 1960s. The changes in the distribution of temporal characteristics of precipitation towards longer events and higher intensities should have a significant impact on the terrestrial hydrologic cycle including subsurface hydrodynamics, surface runoff and European flooding.
