Abstract:
This dataset consists of the .cas and .dat files from the ANSYS Fluent computational fluid dynamics simulation of the air-sea interface under hurricane wind speed conditions. The simulation was done with a very fine mesh resolution to observe fine-scale structures on the sea-surface resembling Kelvin-Helmholtz instabilities. This dataset supports the publication: Soloviev, A.V., Lukas, R., Donelan, M. A., Haus, B. K., & Ginis, I. (2017). Is the State of the Air‐Sea Interface a Factor in Rapid Intensification and Rapid Decline of Tropical Cyclones?. Journal of Geophysical Research: Oceans, 122(12): 10174-10183. doi: 10.1002/2017JC013435

(2012). A very fine mesh with the spatial resolution at the air-water interface of 0.75 x 0.75 x0.75 mm3 was used. The surface tension coefficient at the air-water interface was set at 0.072 N m-1; periodic boundary conditions were set along the x axis; and slippery boundary conditions at the bottom and side walls. The dataset includes two folders: "Flat Surface" and "Wavy Surface" that represent two different simulations. The difference is in the boundary condition. The "Flat surface" has no waves and the "Wavy Surface" has waves imposed through a boundary condition. The different *.dat files are different time steps of the same simulation. The initial *.cas and *.dat file both the wave and flat surface simulations have been provided. Also, a *.dat files have been provided that correspond to each image in Figure 1 and 3 of the manuscript.
