The invention discloses a spherical cloud and precipitation particle swarm scattering simulation method based on a C# and Fortran hybrid programming technology, and belongs to the technical field of weather detection. The method comprises the following steps of firstly, building a meteorological parameter acquisition visual platform; carrying out radar and meteorological parameter input through avisual platform software interface; writing a Fortran source code for a spherical cloud and precipitation particle swarm scattering radar meteorological function needing to be computed and generatinga dll file; carrying out hybrid programming transmission and radar meteorological function intermediate computation, and generating a dll result file; and lastly, reading a content of the dll result file through C#, drawing out a radar echo and an attenuation vertical profile thereof and the like in a simulated mode, and outputting a visual spherical cloud and precipitation particle swarm scattering simulation result. The method has the advantages that the radar echo and the attenuation vertical profile thereof and the like can be drawn out in a simulated mode, the visual spherical cloud and precipitation particle swarm scattering simulation can be realized, and a visual, accurate and rapid basis is provided for learning and researching spherical cloud and precipitation particle swarm scattering.
