Projection of Sea Surface Temperature Based on Empirical Mode Decomposition and Its Application in Typhoon Number Forecast

The primary objective of this paper is to demonstrate the applicability of empirical mode decomposition (EMD) in projecting non-stationary daily sea surface temperature (SST) series, and the other is to apply the projected series of SST to estimate the number of typhoons. The study focuses on an area ranging from 5 degrees N similar to 25 degrees N and 110 degrees E, collecting daily sea temperature data and typhoons records within this region. The findings conclusively indicate that the EMDbased data generation method proposed in this paper can effectively addresses the limitations of previous hydrological models in generating non-stationary series, signifying a significant advancement in hydrological time series modeling for data generation. Furthermore, the study demonstrates the feasibility of using a combination of EMD synthesis and statistical regression analysis to assess typhoon frequency.
