Sea Spray Generation in Very High Winds

Measurement of the Sea Spray Droplet Size Distributions at High Winds

This project will develop cloud droplet probes and phase-Doppler anemometry for measuring sizesegregated droplet concentrations at high wind speeds in the ABL. The data will be used for investigating droplet dynamics in the marine atmospheric boundary layer, characterizing the droplet surface flux source function, and determining the effect spray drops have on air-water surface exchange process...

Mapping High Sea Winds from Space A

Modeling Turbulent Air-Sea Exchange in High Winds

The goal is to investigate, theoretically and through analyzing existing data, the role that sea spray plays in transferring heat, moisture, and momentum across the air-sea interface, especially in high winds. Ultimately, I plan to develop simple, fast, physics-based parameterizations for these air-sea fluxes for use in large-scale models, especially those simulating tropical and extratropical ...

Sea spray spume droplet production in high wind speeds

[1] Sea spray droplets are known to enhance the fluxes of momentum, heat, and mass at the air-sea interface. Evaluating these fluxes depends in part on the so-called “spray generation function”, the size distribution of droplets generated. At high wind speeds, spray is empirically observed to be plentiful near the ocean surface, however, the generation function has remained elusive both theoret...

Physics-based Parameterizations of Air-sea Fluxes at High Winds

The long term goal of this project is to provide a new set of parameterizations of air-sea fluxes, which can be used as boundary conditions for high-resolution numerical models of ocean, atmosphere, and coupled ocean/atmosphere systems. The new parameterizations will be constructed based on physical processes of the exchange of mass, momentum, heat, moisture, energy at the interface between the...
