numerical model run and in the steady states of the low-order model for jJ, = 2.9 X
10- 7 S - I, bo = 500m . The volume transport is given for both and each of the two layers, the terms in the momentum balances are in percent of the total momentum input by
the wind stress. The terms are: interfacial form stress by standing eddies (IS) , interfacial
form stress by transient eddies respectively interfacial friction (IT), bottom form stress
(T) and bottom friction (F).
