One of the most pronounced ramifications in Taiwan is to alter the spatiotemporal dynamics of low-altitude clouds and fog (cloud/fog) in the mountainous region. However, the complex relationship between those anthropogenic perturbations and the cloud/fog spatiotemporal pattern remains unclear. The elevational coverage of cloud/fog (i.e., cloud band) in Taiwan is from 218 to 3011 m a.s.l. covering the primary forest and mountain agricultural ecosystems. Due to long and frequent immersion of cloud/fog, the physical environment of the cloud band is exceptionally humid. Therefore, the cloud/fog-affected mountainous region is an important water source for lowland ecosystems and human-inhabited areas. It also harbors endemic species and cultivated high-valued cash crops that rely on this unique physical setting. Therefore, anthropogenic activities may cause cascading impacts on natural environments and economics. This National Taiwan University-Academia Sinica (NTU-AS) collaborative research project will combine several research methods: Synoptic sensing of mountain climate and cloud/fog, and simulation from the past (1980) to the near future (2050) of trends of elevated temperatures, land use and land cover change and aerosols using community land models to unravel the complex interactions between anthropogenic disturbance and mountain cloud/fog spatiotemporal dynamics across space through time. The outcome of this NTU-AS research project may facilitate an understanding of the cascading impacts of anthropogenic perturbations on natural and agricultural environments in the mountain cloud band.氣候變遷;雲霧帶;暖化;能量收支;水文氣候學;山地霧林;土地使用改變;climate change; cloud band; elevated temperatures; energy budget; hydroclimatology; montane cloud forest; land use and land cover change
