What this study adds:
The boundary layer is one of the least understood areas of meteorology. The lowest kilometer of the troposphere, it is governed by the forces of the Earth’s surface. At night, the boundary layer becomes negatively buoyant, creating a surface inversion layer. However, multiple layers of inversions are often present. In the arctic, stable conditions are nearly constant due to the presence of glaciers and sea ice. These conditions are particularly strong at night. Looking at profiles of the boundary layer from Northern Finland and North Alaska, temperature, potential temperature, wind, and relative humidity were examined in an effort to better understand conditions marking the stable boundary layer. Layered inversions were present over both locations, while Finland showed a more stable environment.
