Observation data from aircrafts equipped with DMT from 200 to 2010，surface observation stations, and satellites are analyzed to explore the macro and micro structures of cloud systems over Shanxi Province，including cloud base height，cloud thickness，cloud particle concentration，liquid water content，and effective cloud particle radius.The depth of stratiform clouds with precipitation is about 2000 m.The mean value of liquid water content of low clouds with precipitation is about 003 g·m-3, and the mean value of liquid water content of middle clouds with precipitations about 005 g·m-3. It is found that there are distinct differences between stratiform clouds with and without precipitation， by comparing their macro and micro physic parameters.To produce precipitation, the effective radius of a stratiform cloud needs to be as large as 10 μm to 14 μm.The maximum super cooled water content appears around the height of 500 m above the 0 ℃ layer for three types of clouds (Scop, Sc, and Ns). According to the size distribution of various particles, the particles with a diameter of 20 and 30 μm has the highest moisture content， making the greatest contribution to cloud liquid water concentration，and the precipitation particles are mainly composed of 20 μm and 30 μm particles.The micro physical characteristics of the cloud structures with different temperature levels are analyzed.
