Significant increases of extreme precipitation and drought events have been detected in Europe in the past few decades. In this study, 16 selected climate indices (11 recommended by the Expert Team of Climate Change and Indices) were used for the analysis of the temporal changes and spatial distribution of precipitation patterns in European plain regions during 1950–2022.

Using an objective, two-step method, 14 plain regions were selected across Europe representing different climatic conditions. Precipitation time series were used from the E-OBS v.27 dataset on a 0.1° regular grid. The dataset is based on station measurements, which are available from 1950 onwards with daily temporal resolution.

Our results suggest a general intensification of precipitation events over the continent, as 11 regions show a significant increase in the indices related to the intensity of extreme precipitation, and the frequency of these events increased in 10 regions. Extreme indices related to dry periods changed significantly in only a few cases. An increase may only be observed in the southern part of the continent, while a significant decrease can be seen in three regions in northern Europe.

过去几十年来，欧洲极端降水和干旱事件显着增加。本研究选取了16个气候指数（其中11个是气候变化与指数专家组推荐的）用于分析1950-2022年欧洲平原地区降水格局的时间变化和空间分布。

采用客观的两步法，在欧洲选择了代表不同气候条件的 14 个平原地区。使用 0.1° 规则网格上的 E-OBS v.27 数据集的降水时间序列。该数据集基于站点测量，这些测量从 1950 年开始提供每日时间分辨率。

我们的结果表明，非洲大陆降水事件普遍加剧，有 11 个地区的极端降水强度相关指数显着增加，其中 10 个地区的降水事件发生频率有所增加。与干旱期相关的极端指数仅在少数情况下发生显着变化。可能仅在欧洲大陆南部地区出现增加，而北欧的三个地区则出现显着下降。
