Wavelet analysis of precipitation changes during 1953-2013 in Fuzhou, China
摘要
Abstract
The annual and seasonal precipitation variation characteristics during 1953 to 2013 in Fuzhou were analyzed by Wavelet Analysis.The results show that: (1) The average annual precipitation in Fuzhou is about 1 366.69 mm.The minimum annual precipitation of 775.3 mm occurred in 1967 and the maximum annual precipitation of 2 074 mm occurred in 1990.(2) Variation in precipitation followed a general pattern of rise-fall-rise-fall-rise-fall-rise that occurred during several time periods.(3) Except for the spring season, the precipitation showed an increasing trend in 61 years.(4) Relatively higher annual precipitation occurred in El Nino years, such as in 1990 and 1997;lower annual precipitation occurred in La Nina Years, such as in 1954, 1967, and 1995.El Nino-southern oscillation (ENSO) events were consistent with Mann-Kendall mutation test.The inter-annual variability of precipitation in Fuzhou was related to ENSO events.关键词
