Abstract

The present invention discloses a meteorological data processing method and apparatus. The processing method comprises: obtaining mesoscale meteorological data, wherein the mesoscale meteorological data is obtained by performing assimilation and numerical simulation on measured data; determining a simulation area corresponding to a target area based on grid distribution of the mesoscale meteorological data, wherein the simulation area comprises a plurality of grid data of the mesoscale meteorological data; performing grouping on the plurality of grid data according to a time parameter and a wind direction parameter of the plurality of grid data, so as to obtain a plurality of grid sets; and collecting statistics on an atmospheric boundary layer parameter corresponding to each grid set, wherein the atmospheric boundary layer parameter comprises at least one of a planetary boundary layer height, a planetary boundary layer wind speed, and a Mourning-Obukhov length. According to the processing method disclosed by the present invention, a technical problem is solved that inaccuracy exists in generating a parameter of a boundary condition by merely subjective setting in a current CFD wind resource assessment technology.

Description

technical field [0001] The invention relates to the field of modeling, in particular to a method and device for processing meteorological data. Background technique [0002] At home and abroad, algorithms based on linear models or numerical simulation technologies based on CFD (computational fluid dynamics) nonlinear models are used for wind resource assessment. Numerical simulation technologies based on CFD (computational fluid dynamics) nonlinear models are also called Numerical simulation of wind resource assessment techniques. Compared with the algorithm based on the linear model, the wind resource assessment technology theory based on CFD numerical simulation is more rigorous, the error is smaller, and the accuracy is higher. In the numerical simulation using CFD, generating boundary conditions close to the real stratification state is a key link to ensure the accuracy of the simulation and thus the quality of wind resource assessment. [0003] At present, the interna...
