Temporal and Spatial Distribution Characters of Tor ential Rain in Qinling Ar ea of Shaanxi Province
摘要
Abstract
The temporal and spatial distribution characters of torrential rain were analyzed by using the method of linear trend, precipitation anomaly percentage, Morlet wavelet analysis and Kriging interpolation, based on the daily precipitation data from 1967 to 2014.The results showed that the torrential rain of Qinling area seasonal changed significantly, and It’s principally appeared in June to September especially in early 1980s and the 21st century.The south and the east parts were more easily suf-fered than the north and the west parts, the torrential rain existed 7 years and 20 years quasi-periodic.Which showed a growing trend in recent years.关键词
