Nonlinear Analysis of Reservoir Rainfall Caused by Typhoon

摘要

Taking measured data of some reservoir rainfall Caused by typical Typhoon and environment variables of typical typhoon as a sample, the nonlinear analysis method is adopted to analyze the relationship between environmental factors of typhoon (including wind speed, wind power, wind circle radius of 7 level and 10 level, central pressure, the distance between typhoon center and the reservoir area, etc.) and reservoir rainfall. Then the form of mathematical representation of typhoon environmental factors and their effects are reduced and optimized. On this basis, the nonlinear analysis model of reservoir rainfall caused by typhoon is made up. Example analysis showed that the model reflects the nonlinear relationship between typhoon environment and reservoir rainfall caused by typhoon to certain extent, and has good fitting results.
