中文摘要:
      利用1995—2017年登陆华南地区的台风登陆时最大风速极值数据,构建基于模糊时间序列的台风登陆时最大风速极值预测模型,并将该模型与传统时间序列ARIMA模型作对比。其预测结果表明,模糊时间序列的平均绝对误差、平均相对误差和均方根误差分别为2.621 m·s-1、0.066和2.727 m·s-1,预测的精确度明显高于传统时间序列ARIMA模型,同时也表明将模糊时间序列应用于登陆时最大风速极值的预测能够获得较理想的预测结果。
英文摘要:
      Based on the extreme value data of the maximum wind speed when typhoon makes landfall over South China from 1995 to 2017, a prediction model of extreme values based on fuzzy time series is constructed, and the model is compared with the traditional time series ARIMA model. The prediction results show that the mean absolute error, mean relative error, and root mean square error of the fuzzy time series are 2.621 m·s-1, 0.066, and 2.727 m·s-1, respectively. The accuracy of the model is obviously higher than that of the traditional time series ARIMA model. At the same time, it shows that the application of fuzzy time series to the prediction of extreme values of the maximum wind speed when typhoon makes landfall can obtain better prediction results.
