焉耆县1951-2010年分季节降水序列变化的小波分析
A study of changes of seasonal precipitations in Yanqi County from 1951 to 2010 with wavelet analysis
摘要
Abstract
Based on the monthly and annual rainfall data from 1951 to 2010 ,the multi-time scales charac-teristics of seasonal and annual rainfall in the past 50 years in Yanqi County have been analyzed using Meyer wavelet analysis in this paper. The periodic oscillation of rainfall variation and the points of abrupt change at different time scales along the time series are discovered and the main periods of every serial are confirmed. It shows that the periodic oscillation of 10-12a and 4-8a for the seasonal and annual rain-falls variation is obvious. The localization characteristics of time-frequency with wavelet analysis can dem-onstrate the detailed structures of rainfall. The wavelet analysis can be an alternative approach to analyzing climate multi-time scales characteristics and forecasting short-term climate variations.关键词
