摘要

The interaction of the storm circulation with the Central Mountain Range(CMR) of Taiwan is studied with a wind profiler located at the leesideduring the invasions of two (Kaemi (200605) and Bopha (200609)) typhoons.The moderate typhoon Kaemi upgraded from a tropical depression on 21 July2006. It then was made landfall at 15:45 UTC on 24 July 2006 near Cheng-Kung.The weak typhoon Bopha formed at about 12:00 UTC on 5 August 2006 and alsolanded near Cheng-Kung at around 19:20 UTC on 8 August. A new finding fromboth typhoons is the vortex splitting into upper and lower parts with thetwo typhoons that have passed the observation site nearly. For the typhoonKaemi, demarcation height of the upper-level vortex and lower level is at2.8 km and passed the site about 3 h earlier than the low-level one. Forthe typhoon Bopha, the center of the lower-level vortex at 3.5 km locates tothe north of the upper-level one at 5.2 km. The re-organization of the splitvortexes is found in typhoon Kaemi but not for typhoon Bopha.
