Abstract: An integrated experiment of precipitation cloud characteristic in Southern Jiangxi from October to December 2015 carried out the comparison of observation data set and the distribution characteristic analysis for precipitation clouds. The comparison analysis of observation data set shows that: the temperature and absolute humidity retrieved by microwave radiometer can be used as high time resolution data set, the radar echoes can be used to retrieve the effective diameter of rain particles, and can also be used as a reference to retrieve the effective diameter of cloud particles when no better data set is available. The preliminary analysis of precipitation cloud characteristic shows that: (1) During October-December 2015 in southern Jiangxi, the precipitation clouds has a higher cloud top with an average height of 8000 m and a thicker cloud with an average thickness of more than 5000 m. (2) The size and vertical distribution of cloud effective particle diameters retrieved by radar, can reflect the distribution of the cloud characteristics to a certain extent. When the average effective particles diameter of cloud is greater than 30 μm and the thickness is up to 3000 m, which has indicative significance to produce precipitation.
