The analysis on the data collected by the Central Weather Bureaus Chiku weather radar and automatic rainfall rate measurement is to identify the characteristics of rainbands under the influence of typ
2009年4月20日午後13時至14時期間,於台南縣東山鄉與白河鎮地區發生了零星小規模的強風致災事件,所幸未有人員傷亡。經事後實地勘災調查與資料蒐集,證實相關災損是由同一起龍捲風個案所造成。本文利用七股都卜勒雷達資料與現勘資料進行探討,初步結果顯示龍捲風母雲發展於鋒面區,以8 m s-1、60度方向移行,其所伴隨之龍捲風最初落地點約在東山鄉西北角,隨後向白河鎮行進,移動距離達7-8公里,生命史約為
(ABSTRACT)本研究擬利用Weather Research and Forecast (WRF)中尺度數值模式,使用代表民國五十年代和現在,兩種不同的土地利用型態,透過Urban Canopy Model (UCM)較正確的參數化都市地表的能量交換過程,並且評估因為熱島效應對於降雨強度所造成影響,表現台北盆地不同程度的都市熱島效應;模式應用沒有明顯大尺度降雨系統(颱風、梅雨)影響的情況下,以
In a mountainous region,the surface slope,orientation (i.e.aspect),and surrounding terrains have a strong impact on the surface SW radiation.Taiwan is a subtropical island with complex terrains.The Ce
The monsoon onset in July over the subtropical western North Pacific (SWNP,15-25°N; 130-150°E) is investigated by focusing on the relationship between the rapid deepening of the monsoon trough and the
