Abstract

This paper adopts wavelet transform to study the phenomena of storm surge based on the observed tidal data. The characteristics of space and frequency distributions of this feature can be revealed by wavelet energy. This analysis demonstrates when weather conditions are stable, the changes of the wavelet energy deviation closes to zero. However, the wavelet energy of storm surge increases along with the typhoon approaching. If the wavelet energy frequency is less than 1 day-1, the distributions of storm surge graph are similar to that of energy curve. Wavelet energy distribution of surge can therefore acquire accurately the time of the occurrence of max surge. Meanwhile, it can reckon the influential time of storm surge on shore from the variety of the wavelet energy.
