Retrieval of Small and Medium-Scale Wind Field Based on Doppler Radar

Compared with the inversion of large-scale continuous wind field, the inversion of small and medium-scale wind field is more difficult. Through the inversion and analysis of small and medium-scale wind field, many disastrous weather can be predicted. It is of great significance to study the formation mechanism of small and medium-scale weather system and the complex structure of atmospheric boundary layer. The GUI interface of MATLAB is used to set the parameters of wind field simulation. Then the radial velocity fields of various small and medium-scale wind fields are simulated according to Rankine mode. Finally, use NIVAP (integration method in natural coordinate system) and EVAPTC (EVAP method for tropical cyclone inversion), wind field inversion methods to invert the simulated wind field, and compare the similarity coefficients of the two inversion results. Through comparison and analysis, we can draw the following conclusions: both these two inversion methods can get better inversion results, but EVAPTC method is slightly better than NIVAP method.
