本計畫打算研究積雲參數化對尺度的關係,本研究內容與前幾年之研究並沒有直接關係,是一個展新的觀念,人人都以為積雲參數化一定和尺度有關,但是卻無人去從事該主題的相關研究。過去的研究發現積雲參數化可分為兩個部分去加以討論,一部分是深的積雲,另一部分是淺的積雲,我們可以假定積雲在500mb 之下,都不會產生降雨現象,積雲在500mb 以上才會有降雨現象產生,再安全的假設降雨數量與深的積雲數目呈正比,如此一來深積雲的數目則和降雨有直接的關係。我們將利用降雨資料判斷深積雲的所在。 This is proposal to study scale dependence of cumulus parameterization. Everybody says cumulus parameterization should be depended on scales but no body does anything about it, this third part of the three- year application; therefore we will in this proposal propose only one year budget. The contents this proposal is entirely different from previous two year's, therefore you may consider this as a new proposal. Previous research result show that cumulus parameterization can be discussed in two separate groups: deep cumuli and shallow cumuli. We can suppose the ones that produces much of the rain are deep ones. Shallow cumuli generally with cloud top below 500mb don』t produce much rain. Therefore deep cloud amount is proportional to rainfall rate. We make use of this relationship and study scale dependence of rainfall rate. 研究期間:9308 ~ 9407
