Abstract

Land and atmosphere interactions are driven by continuous exchange of heat, moisture, momentum, and various gases. Land surface heterogeneity due to topography and land cover leads to heterogeneity in land–atmosphere exchanges resulting in various natural phenomena, such as sea breezes, valley winds, and monsoons, at wide ranges of spatial and temporal scales. Manmade land-use/land-cover change due to deforestation, agriculture, and urbanization modify these exchanges and thus affect weather, climate, water, and carbon cycle at multiple scales. Growing demands for food, energy, and natural resources imply that land-use/land-cover change will continue to intensify in the future. Understanding the underlying process of land–atmosphere interactions is critical for predicting the impact of future land-use/land-cover change on the natural environment.
