The fate of storm-generated near-inertial waves in the Kuroshio-Oyashio Confluence
Here, we present profile time-series of finescale temperature, salinity, velocity, and microscale temperature measurements from EM-APEX floats in the Kuroshio-Oyashio Confluence for two fall-and-winter storm seasons. Wind-stress forcing from re-analysis winds is compared to the observed evolution of inertial HKE and inferred kinetic energy dissipation rates in the surface mixed layer. Inertial HKE changes have similar probability distributions to wind-forcing while dissipation rates are 2 orders of magnitude smaller, suggesting significant losses to horizontal and vertical radiation. We will also compare observations to simulations using the one-dimensional Price-Weller-Pinkel model forced with reanalysismomentum- and heat-fluxes.
