Abstract

The precipitation process is closely related to cloud microphysical characteristics in addition to cloud macroscopically dynamic and thermodynamic conditions. The mixed phase stratiform cloud system is main target of rainfall enhancement over Northwest of China. To understand the precipitation mechanism and develop scientifically operation of precipitation enhancement, it is necessary to study microphysical structure characteristics of the kind of cloud system in depth. Using the cloud physical data measured by airplane in a stratocumulus precipitation process in southeast of Gansu province on 29 June 2004, the microphysical structural characteristics of stratocumulus cloud system were researched. The synoptic background, precipitation and cloud system evolution during flight measurement were presented, and the cloud microphysical characteristics including number concentration, scale size, 2D image and size distribution of cloud particles at different height levels and horizontal level near stratocumulus top were analyzed. The observation indicates the cloud system is consisted of upper pure cold altocumulus and lower stratocumulus. The study shows that vertical and horizontal distribution characteristics of microphysical structure of the stratocumulus are very uneven. The variation of cloud particles characteristic parameter in lower layer of stratocumulus is larger than of stratocumulus upper layer. The water content and big cloud particle concentration increase with altitude. The difference of particle characteristics in similar altitude suggests that the situation of both formation and growth is variant in different horizontal cloud area at same altitude. The liquid water content is high in stratocumulus, and the maximum is 0.34 g·cm^-3 in warm cloud region. There are thermal inversion layers near cloud bottom. The inversion layer near cloud bottom has strong intensity and impact on cloud microphysical structure, including more cloud drop and higher liquid water content near both top and bottom of inversion layer, but it has less obvious influence on larger water drop. The warm rain process is general in stratocumulus, and it is most active in the middle of stratocumulus. The ice phase particles near stratocumulus top enhanced the warm rain process and contribute to rainfall.
