The signs of magnification of the water cycle rate detected by numerous researchers are analyzed here in relation with a climate change. On the basis of concept of characteristic spatiotemporal scales for hydrological processes, there is concluded that, with climate-caused water content increase, in water cycle links the large-scale hydrological processes are to be more frequent and range-increased. Particularly, the latter appears as the large-scale extreme hydrometeorological events probability growth observed over vast areas.
