Model predictions along a trajectory as a function of β.
Actual and model predicted vectors for different β values shown at several points along an empirical path from the first day starting at the S release location. The black arrows represent the actual velocity vectors at the same point. Model predicted vectors corresponding to large β values (red and yellow arrows), are better oriented towards the platform than the those corresponding to smaller β values (blue and green). The non-monotonic speed profile (arrow length) as a function of beta can be seen in the top inset (red border). The standard deviation of the velocity noise is shown as a grey circle around the tip of the predicted velocity vector in the bottom inset (blue border). The velocity vectors corresponding to the estimated value of β that best fits the data (β = 0.273) are indicated by dashed black arrows in the insets.
