太阳黑子和ENSO对日本吉野川流域水文要素影响
Combined influence of solar activity and ENSO on hydrological processes in Yoshino River basin, Japan
摘要
Abstract
Interpretation on the mechanism involved in the "Sun-Climate-Water" system provides scientific guidance on the water resource management. Using correlation analysis, principal component analysis and wavelet analysis ap-proaches, the combined influences of solar activity and El Ni?o Southern Oscillation ( ENSO) on precipitation, river flow and groundwater levels in Yoshino River basin, Japan were investigated. And the results indicate the following:① Significant influences of solar activity and ENSO on the hydrological processes mainly concentrate in the periodici-ties of 11 and 2—7 a, respectively. ② The solar-modulated ENSO plays a critical linkage between solar activity and precipitation/surface water resource. However, this linkage doesn′t act in the Sun-ENSO-aquifer system. ③ Both di-rect and indirect influences of solar activity on hydrological processes in the study area are obtained. The direct influ-ence might act via the function of non-ENSO climate indices, while the indirect influence might act via the process of"ENSO-Western Pacific Subtropical High-East Asian Circulation-Water Movement".关键词
