重要研究與突破
季節的氣候變遷是我們長期關注的議題，藉由研究季節的規律及驟變特徵，期能加深對氣候分佈、變遷的了解。為了更全面認識季節性的源起與演化，我們以氣候動力為基礎研究古季風環流與降雨的特徵。我們探索地軸傾角和日、地間距(歲差、離心率)的改變對季風的影響，漸具輪廓的辨識季節軌道效應對古季風氣候的影響。系列的研究已建構了兩個可靠的機制，分別論述"全新世期間亞洲及非洲季風的差異發展"以及"上次冰期至今海、陸季風共伴型態的演變"；我們分析了季風的氣候模擬結果與古地質、海洋的氣候重建資料，標註了亞非夏季季風主要環流結構逐步發展的演化過程。
以古鑑今之外，我們研究當代季風的年代際氣候變異，獲取暖化趨勢中區域性變化的細節，期能終究掌握短期氣候的可預測性。診斷分析的結果顯示，暖化因子正(將)改變東亞冬季季風大氣環流主要結構間的關係；中緯度西風擾動及中低層季風環流彼此關聯性的疏離便是特徵之一。儘管屢破紀錄的極端天氣事件正日趨寫實的印證了暖化氣候的衝擊! 相較於模擬未來的一種極端氣候狀態，氣候模擬關於人為暖化與自然氣候變異分別的影響仍不可靠! 我們研究年代際尺度的氣候變化，探索不同氣候帶內次季節特徵間的共伴關係，藉此辨識年代際氣候變異全球化的程度；研究的落實有利於檢視氣候模式的能力，精進氣候變遷推估。
我們認為要能全面認識台灣氣候的變異、變遷，需深度理解東亞季節動力與大尺度環流的變化。能夠掌握區域氣候多尺度的變化，也有利對氣候變遷衝擊空品的判讀；我們偶也參考綜觀氣候的研究結果提供影響台灣空氣品質的氣候觀點，近期的研究探索了過去十多年來台灣南、北部區域空品季節性變化的大尺度控制。我們計畫擴大探索近代東亞空汙長期變化趨勢的動力背景。
