Method and system for inverting sea surface wind field based on sea wave two-dimensional spectrum observation data

The invention discloses a method and a system for inverting a sea surface wind field based on sea wave two-dimensional spectrum observation data. The method comprises the following steps: obtaining a wind wave component two-dimensional spectrum and a plurality of surge component two-dimensional spectrums according to an observed sea wave two-dimensional spectrum; respectively calculating parameter data of the two-dimensional spectrum of the wind wave component and parameter data of the two-dimensional spectrum of each surge component; constructing a wind speed inversion basic element based on the parameter data of the wind wave component two-dimensional spectrum, obtaining a wind speed inversion initial model according to the wind speed inversion basic element, and performing correction by using the modulation effect of the surge component to obtain a final wind speed inversion model; establishing a wind direction inversion initial model based on the parameter data of the two-dimensional spectrum of the wind
