[0050] Obtain the wind speed V and wind direction angle W for the current time period; it should be noted that, in this embodiment, the wind direction angle represents the angle between the direction of the wind blowing and due north, and the wind speed and wind direction angle are obtained by measuring with an ultrasonic anemometer;

[0051] Establish a spatial coordinate system with the observation point as the origin, the north direction as the positive direction of the Y axis, and the east direction as the positive direction of the X axis;

[0052] By formula and Decompose the wind speed V and the wind direction angle W onto the X-axis and Y-axis of the spatial coordinate system to obtain the components of the wind speed V and the wind direction angle W on the X-axis and Y-axis and It should be noted that establishing a spatial model of wind speed and direction vectors plays an important role in understanding and predicting wind fields, and is conducive to more accurate analysis and application of wind speed and direction data in the future.

[0053] The acquisition module also includes an optimization unit, which is used to calculate compensation for the measurement error of the acquisition module and use the calculated compensation to adjust the wind speed Q and wind direction angle W in the current time period to obtain more accurate measurement values.

It affects the distribution of wind speed and the transmission of wind stress.

[0077] Through parameterization, complex physical processes can be simplified into models that can be described by a small number of parameters. These parameters can be determined from observational data. The Charnock relationship provides an empirical formula that relates sea surface roughness to wind speed and gravitational acceleration. This relationship can be used to estimate sea surface roughness under wave conditions and thus obtain compensation coefficients.
