| Abstract: | The probability forecast mathematical models describing sea wave surface leaps over a threshold value during certain time is proposed on the basis of the stochastic process of leaps over a threshold value.The relationship between the parameters in the models and the energy spectrum density function of the sea wave is also given.The sea wave surface is simulated, and the models proposed in this paper are verified by means of simulation data.The results show that the probability forecast mathematical models proposed are available ,and by means of the study results the probability forecast of sea wave surface leaps over a threshold value can be carried out convenidntly. |
