• 中文摘要： 本文係針對1975年6月11~12日東南亞梅雨系統之水汽收支研究。此期間之梅雨鋒面曾於臺灣西部地區造成有組織之大量中幅度對流降水。計算結果指出在700毫巴以下之低對流層有大幅度之水平水汽輻合及垂直水汽輻散以維持梅雨鋒面雲帶。同時，發現在積雨雲區內各層之水汽供應，次網格對流傳送過程遠超過大幅度傳送過程。在850, 700, 500及400毫巴上，前者與後者之比?1.5, 8,5, 5及5 。
• 英文摘要： Moisture budget computations are carried out for a Mei-Yu case in Southeast Asia. The case chosen covers the period of June 11-12, 1975, when organized mesoscale convective rainfall is conspicuous over the western Taiwan. Results show that the convergence of horizontal moisture fluxes together with the divergence of vertical fluxes in the lower troposphere below 700 mb is responsible for the maintenance of the Mei-Yu cloud band. It is found that the sub-grid convective process predominates over the large-scale process in providing moisture in the cumulonimbus area, with the ratio of two terms being 1.5, 8.5, 5, and 5 at 850, 700, 500, and 400 mb, respectively.
