Abstract

An airport area multi-source wind field fusion method based on a numerical simulation model and a mesoscale meteorological mode comprises the steps that 1) wind field refined simulation: specifically, an airport area wind field refined simulation technology process based on a CFD technology and a WRF mode comprises the following steps: firstly, based on a boundary wind field of a CFD grid generated based on a WRF mode, simulating wind field information of a research area under different meteorological conditions; secondly, generating a CFD refined grid based on local elevation data and land form features, and importing the CFD refined grid into a CFD mode; based on a boundary wind field generated by a WRF mode, writing into a CFD initial file, and assigning a side boundary grid of the CFD initial file; and finally, calculating and outputting refined three-dimensional wind field data under different meteorological conditions in the research area. and 2) wind field data fusion calculation.

Description

technical field [0001] The invention relates to a multi-source wind field fusion technology in an airport area based on a numerical simulation model and a mesoscale meteorological model, which can fuse wind measurement data from different devices at the same time to obtain a near real-time three-dimensional refined wind field in the airport area. Background technique [0002] Wind field is one of the important factors affecting the safety of aircraft takeoff and landing. From the calculation formula of aircraft lift, it can be seen that the lift received by an aircraft during flight is proportional to the airspeed of the aircraft. Usually, taking off and landing against the wind can make the aircraft receive a greater lift and ensure the safety of the aircraft. However, atmospheric wind is the most unstable meteorological element. Under the joint action of atmospheric turbulence and fluctuations, there are obvious bursts. During the process, it will cause short-distance abr...
