摘要

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.
