個人簡介

過去我在德國萊布尼茲波茲坦氣候變遷影響研究中心(Potsdam Insitute for Climate Impact Research)擔任科學員,此機構為氣候變遷領域的前端智庫,在服務期間得以接觸並熟悉世界各地氣候研究和調適政策的計劃。我所參與的團隊主要是負責歐盟企業自主減碳的轉型路徑評估分析和亞馬遜雨林永續農業發展的計劃。
在亞馬遜的計畫啟發了我在南美洲飛河(Flying rivers or aerial rivers)的研究,我使用地球系統模式輔助追蹤各種不同土地利用型態會對區域氣候造成的影響,並對飛河深深著迷。飛河是長時間尺度下,描述空中水分流動的習慣軌跡。飛河就像流在空中的河,但是無色無味,不易感知,剛好與地上的河相反,受蒸發散補助,透由降雨失去水分。
亞馬遜森林的砍伐,會影響到飛河下端區域收到的雨水和河水(跨越行政和地表水系的遙相關)。舉例來說巴西的砍伐,其實會影響被飛河連結的祕魯居民的用水。我以簡單大氣物理模式描繪南美洲飛河的型態並量化分析亞馬遜的砍伐對飛河下游水資源流失的影響,另提出以管理飛河來減緩玻利維亞水資源危機的政策建議。我的研究提供了第一個飛河與地表河關聯性的科學證據。
而在氣候變遷的減災和調適上,我透由過去歐盟計劃參與經驗延伸出了對社會轉型的研究,我的研究主要是觀察國家政策與社會轉型在氣候變遷造成的衝擊中,是否能達到資源永續。過去我研究哥倫比亞旱災時面臨的水力能源危機帶動了國家能源政策的改變,但是政策設計並未能驅動社會的轉型,另外政策設計也忽略該個例減災上的迫切,對國家能源安全和穩定的效果並不大。
目前我的研究焦點在世界減碳路徑氣候變遷調適轉型永續地水連帶系統(land-water systems)的管理還有飛河研究,除了在歐盟和拉丁美洲的區域深耕點,也新增台灣的在地研究點,並將繼續拓展研究場域與合作社群來豐富學術內涵與對話。

研究室名稱:Surface Processes and Landforms

Current fields of interest focus primarily on Earth's surface processes and landforms. The main goal of my research is to provide relevant information on the dynamics of surface processes, thus enabling the interaction between geomorphic processes and physico-chemical systems. The topics include the following:

1.Landscape dynamics via on-site monitoring and numerical simulation.

a.Badland landscape dynamics
Dr. Yang has published 4 SCI papers related to badland landscape dynamics since 2019, including 3 papers listed as first author, one of them was published in Nature Communications (IF:14.9). As far, Dr. Yang provides a framework to investigate how tectonic and climatic processes on mudstone badland evolution in southwestern Taiwan. The next part of the project aims at generating the spatially complete set of observational constraints on badland landscape.

2.Seismic ambient noise analyses on detection of surface processes.

a. Acoustic ambient noise analyses on the detection of bedload transportation
With this focus on the fluvial process within the active mountain, Dr. Yang applies an acoustic approach to bedload detection and characterization in Liwu River. Specifically, two overarching interests in this project: First, to raise a high-quality, long-term dataset on bedload dynamics and threshold of motion. This will be unique for the typhoon-dominated rivers of Taiwan and can be used to inform local hazard protection measures. Second, use this dataset to investigate how far the extreme conditions of Taiwan lead to similar or different behavior in temporal bedload dynamics in comparison to previous observations and models.

3.Capability and limitation of carbon sequestration of olivine fertilization over various agricultural practices.

The main scope of this project addresses the relation between land use, climatic effects, and the enhanced weathering rate, which needs more detailed and precise observation data to analyze the effect of environmental change on the efficiency of carbon sequestration. Dr. Yang conduct additional olivine fertilization in three standard sample plots with various agricultural practices and monthly water chemistry and the minutes-resolution water stage constrain the result of carbon sequestration.
