The Role of Non‐Local Effects on Surface Sensible Heat Flux Under Different Types of Thermal Structures Over the Arctic Sea‐Ice Surface
Abstract The effects of atmospheric thermal structure on the surface energy flux are poorly understood over the Arctic sea‐ice surface. Here, we explore the mechanism of sensible heat exchange under different types of thermal structures over the Arctic sea‐ice surface by using data collected during...
