摘    要:为了进一步提高降雨量预测精度,在基于小波消噪的基础上应用灰色拓扑对降雨量进行预测,用丹东地区1951年-2007年的降雨量作为历史数据,建立降雨量预测模型.结果表明,新模犁算法简单,精度较高,比传统的拓扑预测模犁效果更好.应用该方法有效的提高了降雨量的预测精度,为降雨量预测提供了一种行之有效的方法,对防灾减灾具有重要的现实意义.

关 键 词:小波消噪  灰色拓扑  降雨量预测

Abstract:In order to improve the accuracy of precipitation forecast,this paper attempts to apply the method of gray topological prediction based on wavelet denosing in forecasting precipitation.Based on the rainfall data from 1951 to 2007 in Dandong,the paper establishes a model for forecasting precipitation.The computational results show that the model is simpler and more accurate than that of the basic gray topological prediction model.Also,the method improves the accuracy of precipitation forecast.The new method ...
Keywords:wavelet denoising  gray topology prediction  forecasting precipitation
