Using typhoon “Weipa” exploring experiment data and the basic observations during September of 2007 from Shanghai Meteorological Bureau, detection performances of multi-channel ground-based microwave radiometer and the relative characteristics of No. 0713 typhoon Weipa before and after its landing are investigated. Results suggest that trends of temperature as well as relative humidity before and after Weipa landing detected by multi-channel ground-based microwave radiometer are in substantial agreement with those from GPS sounding if minor differences between them are neglected, which proves that microwave radiometer has the ability of typhoon detection. In addition, features of sudden outbursts of Weipa landing are detected by microwave radiometer with active shot-lived cold or warm atmospheric column on temperature field and atmospheric column with high water vapor density on vapor field during the landing of Weipa.
