摘　　要：本文利用FACE（佛罗里达积云试验）1978年夏季积云飞机实测资料，对微物理过程的垂直连续性及其和上升气流的关系进行了研究。资料涉及三架带仪器的飞机分别在积云块的－5、－10、和－15℃层反复穿行两架飞机对单层高度连续穿行。本文着重研究这三层高度上与云滴、上升气流有关的冰相的发展，以便了解“触发”快速冰化的机理。An experiment to examine the vertical continuity of microphysical processes in relation to the supporting updrafts was conducted during the Florida Area Cumulus Experiment (FACE) in 1978. Three instrumented aircraft repeatedly penetrated individual cumulus near the - 5, - 10 and - 15℃ levels. Some successive penetrations with two aircraft on a single level were also made. The present study emphasizes the evolution of the ice phase near the - 5, - 10 and - 15℃ levels in relation to both cloud droplets and updrafts, in order to understand the 'trigger' mechanism for rapid glaciation.
