Diagnostic analysis of a strong precipitation process from the aspects of FY2E Satellite Water Vapor Imagery of dry and wet characteristics occurred on 14~17 April 2014 in Inner Mongolia of Bayannaoer City,by using the conventional meteorological data from MICAPS. The results showed that: (1)The vapour bandlocatedinthe deep wet area has a θse ridge axis and the shape and size of vapour band is consistent with it. The maintenance of high θse ridge axis at low layer shows warm air from low latitude Which is conducive to the atmospheric stratification instability appear below the vapour band. Due to the existence of upper troposphere dry intrusion, Internal θse in vapor band is higher than the outside 5 ~ 10 Centigrade. (2)The vapor zone have obvious vertical ascending motion in this precipitation process. The location of vapor band has a good relationship with the positive divergence, negative vorticity and vertical velocity of ascending motion area. On the west side of the boundary and negative vorticity in the upper troposphere are nearly parallel,dark area position with very strong positive vorticity.
