Abstract

The invention relates to a marine climate prediction method and system based on NPSDV driving factor identification. The prediction method comprises the following steps: acquiring sea surface salinitySSS analysis parameters, determining a time sequence of NPSDV and a driving factor index time sequence according to the SSS analysis parameters, calculating a time sequence power spectrum of the NPSDV, a driving factor index time sequence power spectrum, time sequence lag cross autocorrelation of the NPSDV, driving factor index time sequence lag cross autocorrelation and lag cross correlation, reconstructing spatial point SSS anomaly by using the autoregressive process model, determining an SSS anomaly reconstruction result, determining a driving factor according to the time sequence power spectrum of the NPSDV, the driving factor index time sequence power spectrum, the time sequence lag cross autocorrelation of the NPSDV, the driving factor index time sequence lag cross autocorrelation,the lag cross correlation and the SSS abnormal reconstruction result, and predicting the marine climate according to the driving factor. By adopting the prediction method and system provided by the invention, the marine climate can be accurately predicted.

Description

technical field [0001] The invention relates to the field of marine climate, in particular to a marine climate prediction method and system based on identification of NPSDV driving factors. Background technique [0002] At present, the North Pacific Sea Surface Salinity Decadal Variation (North Pacific Sea Surface Salinity Decadal Variation, NPSDV) represents the low frequency of Sea Surface Salinity (SSS) and its atmospheric forcing (ie freshwater flux and wind stress). Effects of Oscillation on Air Temperature, Precipitation, Storm Tracks, Asian Monsoon, Ecosystem and El Niño-Southern Oscillation (El Niño-Southern Oscillation) Oscillation, ENSO) and other weather and climate have an important impact; through the identification of NPSDV driving factors, the predictability of the Pacific ocean climate can be improved to more effectively deal with the extreme weather and climate change risks of countries in the Asia-Pacific region, including China. [0003] However, there ...
