The Application of Grey Model to the Prediction of Extreme Sea States Induced by Typhoon

The sea state of South China is influenced by typhoon obviously. It is important to carry out the long-term prediction of typhoon wind, wave height and wave period for the coastal and offshore engineering. In this paper the measured wind and wave data during typhoon processes from 1964-1989 are used to predict the extreme sea states by using Grey Markov Chain Model. The calculated results show the reasonableness of the proposed method. key words—Typhoon, Extreme sea states, Long term prediction, Grey Markov Chain Model.
