• 中文摘要： 本研究使用一個“近二次元，有時序，無降水”之積雲模式，模擬1963年Glass and Carlson及其他多人所觀測得午前，山峰上階段性成長之積雲群。模擬結果與觀測極為吻合，即是：早期所形成之雲為不能發展之淺積雲；至某一段階後，所形成之雲“突然”能發展至甚高之高度，而成為深積雲。故本研究使吾人對山峰上積雲階段性之成長之物理過程，能獲得一較明確之概念。同時，本研究亦顯示：日出後，山峰上及山坡上之露水及泥土中所含水份之蒸發，對此階段性成長之積雲群極為重要。
• 英文摘要： Employing the quasi-one-dimensional, time-dependent and non-precipitating cumulus cloud modelpresented by Wang [12], a numerical simulation of the characteristics growth feature of the forenoonmountain clouds observed by Glass and Carlson [6] and others has been performed. The results are in ex-cellent agreement with the observed feature in that the early-formed clouds are shallow clouds and thelater-formed clouds suddenly become able to rise to a greater height. With these results and other studies,we have sharpened our concepts about the formation and development of the forenoon cloud activity inmountain regions. And also, we have inferred that the evaporation of dew and the evapotranspiration ofthe water content in mountain surface soil are important for the production of the forenoon mountainclouds which enhances the afternoon cloud activity.
