Weather analysis of a rainstorm process

Analyze the disperse rainstorm weather process in the central and eastern regions of Heilongjiang Province on August 7th, 2013.Discuss the cause of the rainstorm weather with the satellite cloud picture, doppler radar data and dynamic thermal conditions. The results show that this rainstorm process is a convective precipitation caused by the meso-and micro-scale systems; the strong thermal instability stratification serves as the background condition for the meso-and micro-scale systems; In this rainstorm, the ground warm front is the trigger mechanism. The long stop of warm front in the south of Heilongjiang Province is the major reason of the long duration of this convective precipitation.
