Prof. Bin Wang, Dr. June-Yi Lee, and Dr. Baoqiang Xiang of the University of Hawaii (UH) visited APCC in March 2012. During Prof. Wang’s stay from 12 to 14 March, he presented the final report of an APCC international research project which was performed from May 2011 to March 2012 on the “Development of an APCC operational ISO MME system and investigation on Arctic and high-latitude influences on East Asian climate”.

The report included (1)development of an ISO prediction system, (2)transfer of the UH coupled models, (3)implementation of a land initialization scheme, and (3)estimation of the impacts of associated changes in East Asian winter monsoon/cold surges on the weather/climate and socioeconomic human activities in East Asia/Korea.

During the stays of Dr. Lee (12-16 March) and Dr. Xiang (12-22 March), they transferred the UH hybrid coupled model (HCM) and the UH POEM to APCC for an in-house ISO forecast system and 6-month lead climate prediction. Prof. Wang also gave a talk entitled “Why has Arabian Sea storm intensified recently?” In the seminar, he showed that tropical cyclone (TC) intensification is due to advanced TC occurrences, which result in a marked reduction of the vertical wind shear that is five times larger than aerosol-induced change.
