| Abstract: | The relationship of the subtropical South/North Pacific Meridional Modes (SPMM, NPMM) with ENSO was investigated using sea surface temperature (SST) data from Hadley center, Sea surface height (SSH) from ORAS4(Ocean Reanalysis System 4), and wind and air-sea heat flux from NCEP-NCAR reanalysis 1 (1948-2018). Results show that the SSTA associated with the two meridional modes both show north-south dipole patterns and are closely related to ENSO. The significant maximum positive correlation appears when Niño3.4 lags NPMM for 10 months, there are significant maximum positive correlations when Niño3.4 lags for 6 months, with the peak correlation appearing at 6-month lag. In other words, about one year after a positive NPMM (North Pacific:warm in the southeast and cold in the northwest) appears in the north Pacific, or half a year after a positive SPMM (South Pacific:warm in the northeast and cold in the southwest) happens in the south Pacific, and there will be an El Niño event in the tropical Pacific. A binary linear regression model was constructed based on SPMM and NPMM to improve ENSO prediction. The correlation between the reconstructed Niño3.4 and the observed Niño3.4 reached 0.57. |
