Typhoon storm surge intensity estimation method based on Random Forest
To accurately estimate the typhoon storm surge intensity,a typhoon storm surge intensity estima-tion method based on Random Forest(RF)is proposed.Spearman correlation analysis is used to determine the key typhoon parameters affecting the typhoon storm surge intensity.Taking the historical typhoon param-eters and typhoon storm surge intensity data as the sample set,the typhoon storm surge intensity estimation model based on RF is established.55 groups of historical typhoon parameters and typhoon storm surge in-tensity datasets in coastal China from 2000 to 2020 are used to train and test the established typhoon storm surge intensity estimation model.The results show that the accuracy of typhoon storm surge intensity esti-mated by RF algorithm is above 80％and higher than that estimated by C4.5,KNN and NBM algorithm,which verifies the reliability of RF algorithm for estimating typhoon storm surge intensity.
