Estimating Dissipation Rates Associated With Double Diffusion

Double diffusion refers to a variety of turbulent processes in which potential energy is released into kinetic energy, made possible the ocean by difference molecular diffusivities between salinity and temperature. Here, we present new method for estimating dissipation rates forced double-diffusive convection using temperature data alone. The estimates up-gradient diapycnal buoyancy flux associated with double diffusion, hypothesized balance rate. To calculate gradients on small scales apply canonical scaling compensated thermohaline variance (or ‘spice’) sub-measurement fixed gradient. Our predicted compare favorably microstructure measurements collected Chukchi Sea. Fine et al. (2018), https://doi.org/10.1175/jpo-d-18-0028.1, showed that provide good heat fluxes this region. Finally, show maintains predictive skill when applied sub-sampling Conductivity, Temperature, Depth (CTD) data.
