	1	NUMERICAL TEST OF AN EARLY-SUMMER EXPLOSIVE CYCLONE EVENT IN EAST ASIA显示文摘A series of ten numerical tests are carried out using smoothing techniques in the PSU/NACRmesoscale model MM5 initial field in order to study the development reasons of a pre-summeruncommon explosive event which took place in East Asia from 1—2 June.1993.The integrationfields are compared with that of original results obtained by non-smoothed initial field.The resultsshow that:(1)After the northern trough is smoothed,its corresponding cold air can not movedownward and southward.Only a weak cyclone system forms south of 25°N after 24 h integration.(2)After the southern strong moisture transportation channel is smoothed,the northem troughsystem can only form a weak trough along the east coast of China after 24 h integration.(3)Thesetwo separate low trough systems in the southern and northern jet systems,with strong warmmoisture transportation channel and cold air respectively,are both necessary for explosive cyclonedevelopment.In such an unfavorable season and location for explosive cyclone to take place,onlyafter these two low troughs merged into a strong low vortex can the surface cyclone he developedexplosively.Both the northern trough system and the southern moisture transportation channel areall indispensable for the explosive cyclone development.This explosive cyclone event is the resultof the interaction of northern and southern systems.	杨福全 Isamu YAGAI	2000	Acta meteorologica Sinica2000，14，3：	0
