This model can be adapted to calculate the hourly wind at any designed area in the South China Sea influenced by a typhoon.This model employed an atmospheric pressure field model for typhoons set up by our Institute, and considered the following iactors effecting a wind field: the parameters of the typhoon itself, i.e. movement speed, sea surface friction, sea temperature, and the atmospheric pressure field of the environment and has set up an asymmetrical model for typhoon wind fields.By this model. J.E. Overland' s (1975) and C.P. Jelesniski's (1965) model we have respectively calculated a group of typhoons which effect Xisha Island. The computated results obtained by our model was much better than those from the two other models. Through comparison with real observation values from Xisha, the results are very satisfactory.In order to suit vast quantities of computation for long period arrays, we have used the typhoon data base, and worked out an index and computation program for the model. In the luture the arduous task of computation can be handled by computer, and so greatly raise working efficiency.

The formulas of the MEM power spectrum derived from the linear process and Burg's spectral estimates are used to determine the autoregressive coefficient and then the MEM power spectrum of the recorded data of the shorter time sequence in the non-linear harmonic process with noise is found. Firstly, by means of the simulated signals of the harmonics with the given frequency and noise one may search out the pattern to obtain the MEM power spectrum of the recorded data of the shorter time sequence in this kind of processes. Then, the pattern is applied to a real process for finding the MEM power spectrum. The cycle found for the MEM power spectrum accords with the one of the real process, Meanwhile, the regular pattern of the empirical selection of orders for finding the MEM power spectrum of the recorded data of the longer time sequence in this kind of processes is also given in this paper.
