Question: using the table briefly explain which physical forces pressure gradient...

Question details

Using the table, Briefly explain which physical forces (pressure gradient, Coriolis, friction) you expect to dominate the dynamics of the following processes. Which of these processes are dominated by the geostrophic balance: Coriolis force ≈≈ pressure gradient.

(i) Surface waves

(ii) Internal waves

(iii) Tsunami

(iv) Mesoscale eddies

(v) Tides

(vi) Wind-driven circulation

(vii) Thermohaline circulation
