Study of EM Signals Propagation through Marine Atmospheric Boundary Layer and Static Pressure Measurements in Marine Atmospheric Boundary Layer During CBLAST

Abstract

The long-term goal of this project is to acquire physical understanding of the mechanisms controlling the coupling between the ocean and the atmosphere. Through the last decades extensive experimental efforts have been devoted to phenomenological description of air-sea interaction. The goal of such approach is to present air-sea exchange in terms of transfer coefficients, thus encapsulating the complex physics, and parameterizing these coefficients trough one (or small number) of variables. In particular, these efforts included work on determining the ocean surface s drag coefficient, essential in calculating air-sea momentum exchange. The experimental estimates of the drag coefficient have persistently produced scatter that has not been reduced by improving the quality of measurements or by accumulating more statistics. Such situation suggests that the phenomenological description of air-sea interaction possibly reaches its limits and our understanding can only be advanced by a more detailed look into the physics of air-sea exchange. The analysis of pressure measurements from RED and the ongoing CBLAST experiments is aimed at that. My work also continues to be focused on electromagnetic propagation over the ocean with the goal to reduce discrepancies between model predictions and experiments.
