Abstract:	夏季的午後熱對流經常造成致災性的短延時強降雨，快速生成並發展的對流系統經常讓民眾與預警系統無法及時因應。本研究將使用雷達資料來了解對流胞在生命期三個階段(發展期、成熟期、消散期)的微物理變化特徵，透過雙偏極化參數(Dual-PolarimetricMeasurements，DPMs)可以瞭解降水粒子的特徵並探討對流胞隨時間的變化特性。選取Taiwan-Area Heavy rain Observation and Prediction Experiment (TAHOPE)期間的午後對流事件，並使用五分山雷達站(RCWF)的雙偏極化參數資料進行分析，而為了追蹤對流胞加以分析雙偏極化參數特徵隨時間的變化，使用Storm Motion Analysis by Radar Tracking(SMART)系統來辨識與追蹤對流胞，給定的回波門檻(40?
