| Abstract: | In this paper,the spatiotemporal change of annual extreme precipitation events is analyzed using the daily precipitation data observed by 78 meteorological stations in Shaanxi Province during the period 1961-2009. The results show that the threshold of extreme intensity precipitation varied in a range of 18.7-9.5 mm/d,and it decreased northward. The extreme precipitation events in the province occurred mainly in rainy season from May to September,especially during the period from July to September,their dur... |
