本文研究在有地形的條件下建立一熱動力反演方法，使得吾人可以由都卜勒風場的密集觀測中，重建當時的熱力場。本研究使用三維變分分析，但反演所用的所有動量及熱量方程均以追隨地勢座標表示。
　　由於缺乏高解析度的熱動力場真實觀測資料，本研究使用模式在理想地形下所模擬之冷池來做驗證，並估計誤差。結果顯示，本方法反演的壓力與溫度場，其水平及垂直結構相較於模式結果都有很高的一致性，並有良好的時間連續性。
　　接著以實際個案－納莉颱風（2001）對本反演法做初步的測試，雖然礙於種種限制而引用若干假設，本反演法仍可反演出低壓和暖心結構，及颱風強度隨時間減弱的趨勢。
　　本方法可推廣到適用於台灣的複雜地形，將可用來研究地形對天氣系統的影響。
