摘要

亞洲副熱帶潮濕區是中間尺度擾動發生頻率最多區域，民國68年12月17日至21日有兩個中間尺度擾動發生於冷鋒南方，而通過華南地區。本文使用每隔3小時之地面氣象資料，每天兩次之探空資料，以及GMS-I同步氣象衛星資料。針對此兩個中間尺度擾動，做一完整分析研究，以了解中間尺度擾動之結構。

The intermediate-scale disturbances is one of the most frequently observed atmospheric waves appearing Asian subtropical humid region. On the December 17-20, 1979, two intermediate-scale disturbances appeared in south of polar front and passed over the southern china continent.This paper made the observational studies for these lntermediate-scale disturbances, and made clear their verticaI structure. The data used in the study consist of GMS-i satellite information, together with routine synoptic data and sequential radiosonde ascent data.
