短時而劇烈的強風豪雨往往帶來意想不到的不便及災害，這些天氣現象通常是伴隨如鋒面降水、颱風、中尺度對流系統、雷暴或颮線等系統而來，而這些天氣系統皆可屬於中小尺度氣象所研究探討的範疇。隨著先進大氣觀測及遙感探測儀器技術的發展，高時間與空間解析度的觀測資料已可充份的對各類的中尺度天氣現象進行完整的分析。本課程將從介紹中尺度氣象的定義開始，並說明主要的中尺度天氣系統其生成、發展、維持、消散過程及物理機制。探討議題包含大氣對流、穩定度、中尺度天氣系統的動力與熱力結構特徵，地形相關的降水加強機制、氣流變化與微物理過程。學生可尋找有興趣的個案進行資料的搜集分析或預報，分組閱讀研究文獻，並在課堂上以進行報告。
The severe damages were usually caused by strong winds and heavy precipitation, the occurrences of such meteorological phenomena are related to approaching front, typhoon, mesoscale convection system, hailstorm, and squall line etc. Those weather systems can be discussed in the category of mesoscale meteorology. Recently, more complete pictures of mesoscale weather systems can be well documented by high spatial and temporal resolution of observations due to advanced technology on observational instruments and atmospheric remote sensing. This course will start from the introduction in the definition of mesoscale meteorology onto the physical mechanisms in the processes of initiation, development, maintenance, and dissipation associated with the weather systems. Atmospheric convection, stability, dynamic and thermodynamic characteristic are discussed. The details in enhancement of orographic precipitation, the changes of airflow nearby terrains will also be included in this course. The oral presentation is required, students need to collect data, analyze the data, and present the results in the end of semester.
