April Vegetation Dynamics and Forest–Climate Interactions in Central Appalachia

摘要: The study of land–atmosphere (L–A) interactions is an emerging field in which the effects land on atmosphere are strongly considered. Though this coupled approach becoming more popular atmospheric research, L–A not fully understood, especially temperate regions. This provides first in-depth investigation and their impacts near-surface climate conditions Appalachian region Eastern United States. By way statistical analysis, we explore vegetation dynamics, interactions, consequences for climate, along with competing albedo (energy) moisture (evapotranspiration soil moisture) feedback. Based results from linear regression, composite, correlation analyses, conclude that: (1) a statistically significant increasing trend April exists 1982 to 2015 central Appalachia; (2) there was empirical evidence that altered climatic conditions, as indicated by significantly enhanced latent heat flux, 2 m-specific humidity, moisture; (3) dominant biogeophysical process responsible changes could be positive feedback process.
