    Abstract: 台灣東部與東北部2007 年的11 月底遭受冬季豪雨的蹂躪,其災情嚴重性不下於夏季雨暴。至今東亞冬季季風之水文循環的相關研究並不多,我們對於此時節之台灣槽與台灣低壓水文過程的了解亦有限。過去的二個大型觀測實驗(氣團轉變實驗及冬季季風實驗;AMTEX andWMONEX),均未關注台灣周遭的天氣系統而設計。然而事過多年,我們對於台灣低壓動力過程及水氣結構的了解進步有限,使得台灣低壓預報度難有進展。本計畫經由前導研究發現,台灣低壓係寒潮和台灣槽交互作用後的產物。因此,我們需要跳脫固有的鋒面觀點,以不同的角度探討台灣低壓的水氣結構和水文過程。本計畫將與台灣低壓的動力結構並行研究,從台灣低壓的水文過程分析出發,進而探究東亞區域性水文循環,及台灣低壓所扮演的角色。本年度是三年計畫的第二年及明年度第三年計畫。 A winter heavy rainfall event struct northeastern Taiwan and caused mudslides in numerous villages in late November 2007. The scale of damage resulted from winter rainfall is even more severe than that from rainstorms. Few studies in the literature have paid attention to the hydrological cycle of East Asian monsoon during the winter season, and the knowledge of the hydrological process involved in Taiwan trough and Taiwan low is limited. The past two field experiments (Air Mass Transformation Experiment and Winter Monsoon Experiment; AMTEX and WMONEX) were designed without concerning the weather systems in the vicinity of Taiwan. It is revealed from our pilot studies that Taiwan lows are very different from midlatitude fronts regarding to their dynamical and hydrological structures. Therefore, a new perspective of the hydrological cycle and structure of Taiwan lows should be established. The proposed research will investigate the hydrological process of Taiwan lows, the regional hydrological cycle in East Asia, and the role of Taiwan lows in this aspect. This is the second and third year proposal of the three-year project. 研究期間:9908 ~ 10007
