This data is large eddy simulation model output of turbulent airflow over misaligned surfaces waves (up to 90 degrees) for strongly forced to weakly forced conditions (wave age up to 10.95) using a wave-following mapped coordinate, for the following manuscript: Manzella, E., Hara, T., Sullivan, P. Reduction of Drag Coefficient due to Misaligned Surface Waves. (Manuscript in preparation) From these data for wind aligned with waves (0 degrees) to wind misaligned with waves (22.5, 45, 67.5, 90 degrees) and wave age (c/u*=1.37, 5.48, 10.95) with corresponding variable names (1x, 4x, 8x) we look at equivalent roughness length and wave growth/decay variables. In addition to the cross-wave component of the velocity (v), we also include the rotated along-wind (U) and cross-wind (V) variables. We look at horizontally averaged vertical profiles of the following: -Wind speed, wind shear, wind speed angle, and wind shear angle -Turbulent kinetic energy -Energy budget (including shear production, transport, and viscous dissipation) -Momentum budget (including pressure stress, turbulent stress, and wave-coherent stress) We also look at phase-averaged flow fields of the following: -Wind speed (horizontal and vertical) -Pressure -Turbulent kinetic energy -Dissipation rate -Vorticity (cross-wind) -Turbulent and wave-coherent stress -Pressure, turbulent tangential stress, and turbulent normal stresses (surface distribution) Finally, we look at cross-wind turbulent instantaneous vorticity fields for the 0 and 90 degrees for the lowest and highest wave ages
