Annual Precipitation Time Series Analysis of Poyang Lake

Article Preview

Abstract:

In this paper, the time series of annual precipitation of Poyang Lake were analyzed which use timing diagrams, autocorrelation analysis, the center moved smoothed analysis spectral analysis and other methods. It was found that the time series of annual precipitation of Poyang Lake is a random strong non-stationary time series; there is a slow increase in long-term trends and changes in the quasi-periodic sequence of 3 years and 25 years.
