"Modeling Near Inertial Internal Wave Response in a Seasonally Ice-Free Arctic: Differences from a Mid Latitude
Abstract
We propose to adapt a leading model of mid-latitude internal wave generation to explore the role of diminished ~ and shallow mixed layers in causing reduced generation of internal waves inthe Arctic Ocean and to compare the results to our ongoing SIZRS observations and the SODA observations of others. We will model near-inertial wave propagation through the stratified ocean by recreating the linear internal wave model developed by Zervakis and Levine [1995] that was previously used to accurately model the oceanic response in the ONR-sponsored OceanStorms experiment. Recreating a computationally inexpensive, relatively simple linear model should provide an effective way of testing our understanding of the forcing of the near-inertialinternal wave field in the Arctic Ocean while directly addressing two of the main questions proposed in the SODA DRI:(1) How efficient are Arctic storms at exciting inertia-gravity waves in the more open ocean in summer in the Chukchi and Beaufort Seas?(2) What are the strength and spatial scales of inertial waves being generated and what role do they play in mixing in the Chukchi and Beaufort seas?
