Abstract Regional climate change affects natural processes, including the amount of precipitation and the spatiotemporal differentiation of areal precipitation. The study of such changes is especially important for the Crimea due to the aridity and the lack of water resources therein. In this study, we carried out regression modelling of the areal precipitation in the Crimea using data from 24 weather stations. The maps of precipitation in the Crimea within set epochs and periods were calculated based on the classification of atmospheric circulation processes in the Northern Hemisphere. The trends in the spatiotemporal dynamics of atmosphere areal precipitation due to the change in dominant circulation groups were shown. In general, the territory of the Crimea was characterised to have increasing precipitation during the period of instrumental measurements.

克里米亚降水年际变化的时空方面

摘要 区域气候变化影响自然过程，包括降水量和区域降水的时空分异。由于克里米亚干旱且缺乏水资源，因此研究此类变化对克里米亚尤为重要。在这项研究中，我们使用来自 24 个气象站的数据对克里米亚地区的降水进行了回归建模。根据北半球大气环流过程的分类，计算了克里米亚特定时期和时期内的降水图。显示了主导环流群变化导致的大气区域降水时空动态变化趋势。一般来说，
