The Wind Synthesis System using Doppler Measurements (WISSDOM) is a practical scheme to derive 3D winds by using 11 radars in this study. The observations of shot-wavelength radars can be attributed to lower level precipitation and wind information in WISSDOM, which allowed for the capture of stronger updrafts in the convection areas of the squall line. Overall, these results highlight the advantages of using radars with multiple wavelengths in WISSDOM, especially shot-wavelength radars.
