Embodiment
[0139] The invention discloses a method for merging meteorological data and generating a numerical weather forecast, comprising the following steps:
[0140] Step 1, collect and receive various meteorological element data, and obtain the meteorological element set X 1 ;
[0141] Step 2, performing standardized preprocessing on the collected meteorological element data to obtain a standardized meteorological element set X;
[0142] Step 3: Perform three-dimensional data variation assimilation on the meteorological element set X, and perform characteristic error analysis and cross-covariance analysis on the data in the meteorological element set X to obtain the covariance error mean square of each data in the meteorological element set X According to the root mean square of the covariance error, the optimal type of meteorological element data is obtained;
[0143] Step 4, compile the WRF numerical weather forecast model according to the optimal meteorological element data type...
