Climatologic run
Les comparaisons avec les papiers de Webb(2000) et Qu and Lindstom(2002) sont discutés dans le rapport
Comparison with Ridgway and Dunn (2003):
Bifurcation along the Australian coast
- The latitude of the bifurcation varies with depth from 14.5°S at the surface to 19.5°S at 1000 m depth, not linearly
- function of latitude 15S-17S 18S-20S 21S-23S
- 25m depth 95m depth 182m depth 272m depth 364m depth 732m depth 1033m depth 1406m dept
Suivi de particules lagrangiennes avec ARIANE
- On considere un champ de vitesse stationnaire. Chaque expérience est faite en initialisant les particules à la meme profondeur
- On échantillone les particules dans le SEC: particules_forw_jets
- trajectoire back 163e: back_163e
- On échantillone les particules dans l'EAC: EAC_back
- On echantillone les particules dans le NQC: NQC_back

interannual run for the 1992-2002 period
Along the New Zeland-Japan XBT line:- To illustrate the variability, we look at a section at 17°S between 146°E and 150°E (between the coast and a sea mount): meridional velocity
