Modeling and parameterization of mean and eddying flow over topography

Abstract

Here I propose to carry out pre- and post-cruise numerical modeling for the FLEAT program, meant to elucidate the mechanisms driving enhanced turbulence due to mean and eddying flows in the vicinity of the West Mariana Ridge. The Ridge shows up as a potential hot spot of mean-flow lee-wave generation (Nikurashin and Ferrari, 2011), and enhanced internal wave activity and inferred turbulence (Whalen et. al., 2012). Here we propose to run numerical simulations capable of resolving the dissipation near the topography and the internal wavefield aloft to guide the experiment, and help devise improved estimates of how much dissipation there will be and where it will take place. Because the topography and mean currents will be in the model, we can also look at island wakes and other topographic effects on the mean current. I am requesting funds for travel, disk space, and publication costs.
