Stochastic Simulation of Typhoon in Northwest Pacific Basin Based on Machine Learning

Figure 4

The differences of correlation coefficient and RMSE of typhoon translation speed predicted by the BP model (ANNa2) and regression model (formula 1(a)) for each grid cell. The differences of correlation coefficients from the BP model and the regression model for (a) easterly and (c) westerly headed storms. The differences of RMSE from the BP model and regression model for (b) easterly and (d) westerly headed storms.
