Abstract:

We employ Morlet wavelet transform to analyze the periodical characteristic of salinity change in Lianyungang coastal sea area from 1965 to 1994, Results indicate that salinity change in Lianyungang coastal sea area has periods of 14 years and 5 years for the past 30 years. Salinity mean value is 29.39. It is obvious for the periodic characteristics of salinity change.

Key words: salinity, wavelet transform, periodicity
