The impacts of the BOBM onset on the SCSM onset and the relationship between the two monsoons are also analyzed. The two main results are as follows： （l） The BOBM onset obvi- ously occurs earlier than the SCSM onset in 2010, which is a typical onset process of the Asian monsoon. During the BOBM＇s onset, northward jump, and eastward expansion, convective precipitation and southwest winds occurred over the SCS, which resulted in the onset of the SCSM. （2） The relationship among strong convection, heavy rainfall, and vertical circulation configuration is obtained during the monsoon onsets over the BOB and SCS, and it is concluded that the South Asian High plays an important role in this period.展开更多

The speech scripts and video excerpts from the subsequent manuscript collection with the CD-Rom published by FLTRP were studied. Lucas＇ framework of speech communication process was borrowed to bridge elements of the communication models and speech delivery process. Three key aspects of the speakers＇ encoding endeavors were under close examination： the verbal preferences, the non-verbal preferences, and the topic selection for exemplification. It was found that successful speakers demonstrated a clear and strong audience orientation. They chose more first person pronouns, fewer abstract words, a controlled number of dependent clauses, clear transition words, and limited figures of speech. They used very few verbal fillers, slips of tongue, a moderate speech rate and varied tone inflections. The speakers also showed distinctive features in gestures, eye contact and facial expressions. They employed anecdotes which shared a common field of experience. Pedagogical implications on the teaching of public speaking were discussed.展开更多
