The temporal and spatial characteristics of precipitation in the HRB (Huai River Basin) were studied using the observation data of monthly precipitation provided by the National Climate Center from 1961–2016 and the NCEP/NCAR global monthly reanalysis data. The results showed that: (1) The precipitation was mainly concentrated in summer, accounting for 52% of the total annual precipitation; there was more precipitation in the south, less in the north, and more in the coastal areas, less in the inland in summer; (2) The precipitation showed obvious decadal variations, especially in summer; the range of variation of most regions is above 140 mm; and significant decadal abrupt changes of precipitation from “abnormally less” to “abnormally more” appeared around 1979.
