Abstract Using IDL and based on the VIRR and MWHS instruments on the FY-3 satellite, the authors developed a software called "FY-3 microwave humidity 3D visualization display". According to different monitoring periods, the software can automatically generate a series of pictures composed by VIRR B6,B2,B1 and microwave humidity distribution at 4 different altitudes (ground, 850 hPa, 500 hPa and 300 hPa) from MWHS (day), or can generate a series of pictures from black body temperture(TBB) of VIRR B5 and microwave humidity distribution at 4 different altitudes from MWHS (night). The utilization of this software in tropical cyclone‘SOALA’and rainfall monitoring shows that the 3D visualization, which combines and strengthens the advantages from VIRR and MWHS data on FY-3, is simple and easy to understand. The software can be a useful means in monitoring and warning of severe weathers such as tropical cyclone and rainfall.
