Abstract:

Deforestation is a major driver of climate change and monsoon variability, and can significantly impact regional and global climates. Satellite data indicates that in the Maritime Continent (MC) about 263,000 km2 of forest, an area larger than the United Kingdom, has disappeared from 2000 to 2014. Despite the expansive deforestation over a climatically sensitive region of the tropics, the resulting impact is unknown. Here we show using observations and a large ensemble of Model experiments that deforestation into farmland and urban warms the MC, producing rainfall in northwestern MC but large-scale drying north and south, weakening the South Asian summer monsoon. Our model projects that continued deforestation can contribute to significant changes in Asian monsoon climate in the coming decades

Leo Oey 廈門大學講座教授，他是國際上最著名的海洋模型－普林斯頓海洋模型（POM）開發者之一。目前，他領導的POM已經實現了數據同化、浪－冰－流耦合、大氣－海洋耦合過程，并實現了并行化及非靜壓假設。近年來， 其對臺灣海峽及中國南海的動力研究走在國際前沿。他利用地形羅斯貝波理論結合模型實驗說明了臺灣海峽跨海峽海流的動力機理，很好地解釋了大陸漂流物到達臺灣的原因；利用Kalman濾波數據同化模型在模擬了呂宋海峽三層輸送結構，還利用位渦及物質通量守恒解釋了該結構的機理。目前還兼職為JGR-ocean雜志 編緝。
