Based on daily minimum temperature data during 1979–2013, the frequency of occurrence,the beginning date and ending date and other characteristic values of cold waves at all levels are processed. Then, by using the method of Mann–Kendall method, correlation analysis, empirical orthogonal function and Morlet wavelet analysis, the spatiotemporal distribution and inter-annual variation and other characteristics of cold wave, strong cold wave and ultra-strong cold wave of Shandong Province are analyzed. The tendency of cold waves at all levels in Shandong Province is predicted for the coming years, which might be referable in the prevention of cold wave and storm surge disaster.
