Using the denselyobserved hourly precipitation (>1 mm) data of the automatic weather stations (referred to as the all stations) and the national meteorological stations (referred to as the national stations) in Shandong Province from April to October 2008-2017, this paper compares the characteristics of spatiotemporal distribution of extreme shorttime severe precipitation with different resolution data. The results are as follows. The skewed characteristics of hourly precipitation at all stations are more obvious than those of the national stations. For the average state of hourly precipitation, both are representative. However, for the analysis of the extremes of shorttime severe rainfall, the all stations data are more advantageous. It is most reasonable to use the 99.5th percentile of each station as the threshold for extreme shorttime severe precipitation. The spatial distribution characteristics of the 30-45 mm threshold are similar for all stations and national stations. For thresholds above 45 mm, the values and ranges of all stations are both greater than those of the national stations. The extreme shorttime severe precipitation intensity in most parts of the province is concentrated at 40-60 mm·h-1, and the spatial distribution characteristics of all stations and national stations in this interval are similar. Nationalstation data can not reflect the spatial distribution of extreme shorttime severe precipitation with intensity below 40 mm·h-1 and above 60 mm·h-1. The spatial distribution characteristics of extreme shorttime severe precipitation intensity are closely related to geographical location and topographical features. The extreme shorttime precipitation intensity, daily maximum precipitation, summer precipitation and annual precipitation in the southeastern Shandong Province rank first in the province. Although the frequency and intensity of severe precipitation are high in northwestern Shandong, they have no positive correlations with annual precipitation and summer precipitation. The monthly and diurnal variations of the extreme shorttime severe precipitation frequency of all stations are consistent with those of the national stations. However, the nationalstation data can not fully represent the monthly and diurnal variations of the extreme shorttime severe precipitation intensity in the province. The data of all stations can more accurately reflect the time variation features of precipitation in the province.
