Abstract:Based on the global climate prediction system NMEFC_CESM of the National Marine Environmental Forecasting Center, this paper assimilates the HY-2B satellite and multi-source satellite remote sensing fusion types of sea surface temperature data to establish the initial field, and constructs a satellite-based El Niño/La Niña ensemble prediction system. To explore the influence of satellite remote sensing data initial field on the ENSO prediction error, three types of sensitivity numerical experiments were designed by changing the initial field: The first type includes the assimilation of sea surface temperature and the comparison experiment of assimilating reconstructed three-dimensional sea surface temperature; The second type is the assimilation of reconstructed three-dimensional sea surface temperature, with two groups of comparison experiments before and after sea surface height correction; The third type is to reduce the initial field error of satellite data by half, and test its impact on the ENSO prediction error. The experimental results show that the prediction initial field constructed by assimilating multi-source satellite fusion is more accurate than that constructed by the single-star sea surface temperature data of HY-2B, and the ENSO prediction results are more stable and closer to the observation; Only assimilating the surface sea temperature and differentiating the subsurface sea temperature, the effect of ENSO prediction is poor, even if the initial field error is reduced, it will not produce a substantive improvement, indicating the importance of subsurface assimilation for ENSO prediction; The prediction results using the reconstructed three-dimensional sea surface temperature corrected by sea surface height as the assimilation data source are significantly the best, indicating the importance of sea surface height correction for subsurface sea surface temperature reconstruction; When the initial field error is reduced by 50%, the 12-month average absolute error of Niño3.4 drops below 0.5 ℃, and the prediction accuracy significantly improves, especially for events with relatively large prediction errors.

Key words:ENSO prediction error; initial field of satellite data; dynamic experiment; multi-source satellite fusion; reconstruction of three-dimensional sea surface temperature
