Precipitation data from 30 stations in the Huaihe River basin (HRB), a climatic transitional zone in east China, were used to investigate the spatiotemporal variability and trends of extreme precipitation on multitimescales for the period 1961–2010.
Results indicated that (1) the spatial pattern of the annual precipitation, rainy days, extreme precipitation, and maximum daily precipitations shows a clear transitional change from the south (high) to the north (low) in the HR; it confirmed the conclusion that the HRB is located in the transitional zone of the 800 mm precipitation contour in China, where the 800 mm precipitation contour is considered as the geographical boundary of the south and the north.
(2) Higher value of the extreme precipitation intensity mainly occurs in the middle of the east and the central part of the basin; it reveals a relatively distinct west-east spatial disparity, and this is not in line with the spatial pattern of the extreme precipitation total, the sum of the precipitation in 95th precipitation days.
(3) Annual precipitation of 22 stations exhibits increasing trend, and these 22 stations are located from the central to the northern part.
There is no significant trend detected for the seasonal precipitation.
The summer precipitation exhibits a larger change range; this might cause the variation of the flood and drought in the HBR.
However, the increasing trend in winter precipitation may be beneficial to the relief of winter agricultural drought.
Rainy days in 12 stations, mostly located in and around the central northeastern part, experienced significant decreasing trend.
Extreme precipitation days and precipitation intensity have increasing trends, but no station with significant change trend is detected for the maximum precipitation of the basin.
(4) The spatiotemporal variability in the HRB is mainly caused by the geographic differences and is largely influenced by the interdecadal variations of East Asian Summer Monsoon in eastern China.
The output of this paper could provide references for the practical decision making and integrated basin management of Huaihe River basin.
