    Abstract: 在風洞實驗中,利用X型熱膜探針量測三維 風速,取得複雜地形地區之三維風場。同時以 診斷式風場模式模擬分析,使其滿足質量守恆 定律,並加入地形效應之影響,最後使其風場發 散量為最小,以建立不均勻之風場。運用風洞 實驗所測得之資料,修正診斷式模式中參數化 之公式及係數,如風速剖面指數、衰減係數、 和W項公式等,而使模式模擬之預測值與實驗量 測值差異最小。將預測值與量測值之資料製成 散布圖,由圖上可得知兩者之差異與其線性關 係。經修正後之風場模式,其預測值與量測值 之差異甚小,並且由於複雜地形而對風場產生 之影響,如上坡段加速現象、下坡段減速現象 及渠道效應等,皆有正確而適當之描述,表示符 合物理意義,故顯示其模擬之結果相當合理。
