Morlet小波在铜陵降水序列分析中的应用
Applications of Morlet wavelet to the analysis of precipitation series in Tongling city
摘要
Abstract
Based on the 49 years annual and monthly precipitation data, Morlet wavelet and Mann-Kendall methods were used to analyze the precipitation series in Tongling city, southern bank of Yangtze River. The results showed that:(1) Annual precipitation decreased at a climate tendency of -11.214 mm/10a during 1960-2008.For seasons, winter precipitation increased significantly while other seasons decreased. (2)The wavelet analysis showed both annual and seasonal precipitation had several kinds of periodic change. Abrupt change points increased on small time scales. (3) The research area was in the terminal cyclical period of low-water, ft was predicted that a new cyclical period of high-water would come around in 2010.关键词
