Across Channel Momentum Balance Geostrophic balance (frictionless, steady and linear motion) in the lower layer y z LNM h1h1 h2h2

2
Geostrophic Balance in the upper layer Geostrophic Balance in the lower layer: y z LNM h1h1 h2h2

Observed slope: 2m in 10 km 2 / 10 4 = 2 x 10 -4 f = 8.8e-5 u 1 = 0.08 u 2 = -0.025 rho 1 = 1020 rho 2 = 1024

Could you draw the pressure field (isobars) associated with these salinity (density) fields? u 1 = 0.10 m/s u 2 = -0.05 m/s ρ 1 = 1017 kg/m 3 ρ 2 = 1022 kg/m 3 f = 8.8 e-5 s -1 u 1 = 0.08 m/s u 2 = -0.06 m/s ρ 1 = 1021 kg/m 3 ρ 2 = 1023 kg/m 3 f = 8.8 e-5 s -1 Observed = 2 m in 8 km = 2.5 x 10 -4 Observed = 7 m in 8 km = 8.8 x 10 -4

10
Generally, the outflow modified by rotation will be restricted by the internal radius of deformation R, derived from geostrophy: Scaling: Internal Radius of Deformation or Internal Rossby Radius L
