The Amur River Basin is one of the most sensitive areas to the effects of climate change. In this study, spatial and temporal analysis of concentration index over the Amur River Basin in northeast China was presented. Precipitation data from 71 meteorological stations for the time series 1980-2018 on daily scale was employed in the study. The results indicated that precipitation events of low-intensity accounted for 28.59 % of rainy days, however, the proportion of rain amount was 1.33 %. On the contrary, high-and very high-intensity events accounted for 40.34 % of rainy days and as high as 90.53 % of annual precipitation amount. Precipitation concentration explain the cause of why some regions are prone to be influenced by high intensity precipitation events, spatial distribution of different intensities can be partly interpreted by daily rainfall heterogeneity and regional geomorphology. Furthermore, a significant change toward a stronger precipitation concentration was demonstrated over some regions, and this need concern from the administration.

Рассматривается преобразование гидрологического режима р. Амур, обусловленное глобальным потеплением климата в регионе. На основе проведенного в ИВЭП ДВО РАН анализа трендов температуры воздуха и количества атмосферных осадков на метеостанциях в разных частях бассейна Амура с длительными рядами наблюдений оценены темпы изменений основных метеорологических параметров. Установлено, что на климатические изменения наиболее заметно реагируют амплитуда максимальных годовых уровней воды, активность русловых процессов и смещение сроков ледовых явлений. Они происходят на фоне антропогенного воздействия, роль которого наиболее существенна на локальных участках. Показано, что изменение гидрологического режима в бассейне реки Амур увеличит риск опасных природных процессов в дальневосточном регионе.The transformation of hydrological regime of the Amur River caused by the global warming in the region is considered. Based on the conducted by the IWEP of FEB of RAS analysis of the air temperature and precipitation amount trends at the meteorological stations in different parts of the Amur River basin with longtime series of observations, the rates of changing the basic meteorological parameters were evaluated. It has been established that the amplitude of the maximum annual water levels, activity of the river bed evolution and drift of ice phenomena times react more noticeably to the climatic changes. They come against the background of the anthropogenic impact a role of which is most critical at the local sections. It was shown that a change in the hydrological regime in the Amur River basin will enhance a risk of the dangerous natural processes in the Far-Eastern region.
