方思惟老師研究介紹 Prof. Shih-Wei Fang and his research interest

Hello everyone,

I am Shih-Wei Fang, a new assistant professor joining the NCU-AS family. I received my Ph.D. degree in Earth System Science at UC Irvine, USA and have experienced two post-doctoral research at Max-Planck Institute for Meteorology in Hamburg, Germany and IBS Center for Climate Physics in Busan, South Korea. My research focuses on climate-related topics, including El Niño-Southern Oscillation (ENSO) Dynamics, Paleo-climate changes from volcanic eruptions, and Climate impact on ancient human evolution.

Specifically, one current research is on volcanic impacts on ENSO dynamics (Fig. 1), which investigates how volcanic eruptions from different locations and amplitude can displace the tropical precipitation, or the Intertropical Convergence Zone, and further influence the probability of the existence of distinct ENSO types. Another research topics is to understand how past climate changes may alter the DNA diversity of our ancestors, Homo lineages, through the changes in food availability and their habitat feasibility (Fig. 2). With these diverse interests, I am looking forward to work on more exciting and more essential research in NCU-AS.

大家好，

我是方思惟。這次新加入中央大氣的助理教授。我的地球系統科學博士學位是在加州大學爾灣分校所拿到的，那之後有兩個博士後的經驗，分別在德國漢堡的馬克斯·普朗克氣象研究所以及位於韓國釜山的基礎科學研究院氣候物理研究所任職。我的研究方向主要聚焦在古氣候相關的研究，包含聖嬰現象的動力變化，火山爆發對氣候的影響，以及氣候對人類演化的影響。

其中一個正在做的題目是『不同類型的火山爆發對聖嬰現象的影響』。我發現北半球的火山爆發會造成赤道降雨的南移，也就是熱帶輻合帶的南移，進而更容易產生強度大的聖嬰現象，另一方面，南半球的火山會造成將與北移，但只會造成較弱的反聖嬰現象（Fig.1）。另一個題目是『90萬年前的劇烈氣候變化對古人類DNA的影響』。我發現90萬年前的中更新世氣候轉變造成氣溫驟降並降低食物來源，使得匠人的生存變得不易，古人類的DNA多樣性大幅減少。很高興能夠能夠加入中央大氣，希望之後能在這邊做出更多更好的研究。
