Mechanism of high-frequency tilt-energy transfer

Determine how energy is transferred across the observed mooring-line vibration frequency range from sub-inertial frequencies of approximately 0.1–1 cycles per day to Strouhal frequencies of order 10^5 cycles per day.

Background

The study detects tilt variations spanning an unusually broad frequency range. Very-high-frequency variations appear quasi-random and resemble white noise, while their variance changes with the intensity of convection turbulence. The conclusion notes that these variations may reflect environmental responses rather than purely instrumental noise, but the mechanism connecting the different scales and frequencies is not established.
