The meteorological elements will affect the propagation of the radio wave. These meteorological elements can be reflected by the atmospheric refractive index, which is derived from the pressure, temperature, relative humidity, and vapor pressure. Using the atmospheric sounding data, a real atmospheric refractive index model for an identified area can be obtained. Combined with the refractive index model, the atmosphere can be divided into layered media with different refractive index, and a numerical model can be established to indicate the wave propagation path. The numerical solution results are verified by the analytical solution and other presented model. Due to its high accuracy and computational efficiency, the proposed numerical model can be used to quickly illustrate the physical path of radio wave atmospheric propagation, providing theoretical guidance for related applications.
