Effects of wave kinematics on coastal atmospheric boundary layer

Air-sea interaction can significantly affect the coastal atmospheric boundary layer and consequently, the local atmosphere. Despite its importance, our knowledge of coastal air-sea interaction is limited and weather prediction models frequently generate erroneous predictions for coastal conditions due to a lack of an appropriate parameterization. Land topology, significantly varying thermal conditions across land and water, and oceanic processes such as ocean waves and wave breaking can all add to the complexity of a coastal atmospheric boundary layer, making its study difficult.  In this work, we incorporate the wave effects to the simulation of coastal atmospheric boundary layer. We use an in-house large-eddy-simulation code that utilizes the immersed-boundary method to capture swells and includes a varying sea-surface roughness model. The wave kinematics are extracted from a phase-resolved wave simulation that considers a realistic bathymetry, and the sea-surface roughness is determined via a dynamic model. The findings of this research will help to improve the understanding of air-sea interaction in coastal areas and will aid in the development of coastal weather forecasting models.
