fingers. The axes are labeled with the number of grid nodes. The strongest fingers appear in
the region of maximum shear where the vertical T–S gradients are also the largest. … (b)
The ratio of the rms intrusion velocity and temperature as a function of a. This ratio is
approximately 50% of the linear theory constant U 0 /T 0 = 0.85 (see discussion in text). …
The ξ-independent intrusion signal appears as one fresh and one salty band of salt fingers …
