Presentation of ARIIS method and results from FLIP at AGU in the Boundary Layer Processes & Turbulence (A23D-07)

The R/P FLIP, owned by the Office of Naval Research and operated by Scripps Institution of Oceanography, deployed as part of the CASPER-West field campaign.

Kolmogorov's concept of an inertial subrange within the energy spectrum of high Reynolds number turbulence is fundamental to our understanding of turbulence structure and theory. However, there are significant gaps in how it has been typically applied to study geophysical turbulence. ARIIS is a new approach to identifying the most probable bandwidth of the inertial subrange in a measured turbulence record. ARIIS was applied to study the variance of the inertial subrange slope, which is presumed to be near -5/3, in the airflow new the air-sea interface. 

Here are the slides (**modified for distribution here**) I presented at AGU. ARIIS and the findings of this study are summarized in a pair of papers currently out for JTECH and GRL. These studies provide one of the most comprehensive evaluations of Kolmogorov's inertial subrange -5/3 power law in a geophysical regime, as well as new evidence for a distinct wind-wave-turbulence interaction mechanism that has not been described before and may provide new insights into the unique physical dynamics near the critically important air-sea interface.
