2009/1/5
A numerical model simulation investigates the influence of the mid-Atlantic ridge on nonlinear first-mode baroclinic Rossby waves generated by seasonal wind fluctuations. The North Atlantic is simulat...
Estimates from Altimeter Data of Barotropic Rossby Waves in the Northwestern Atlantic Ocean
Altimeter Data Northwestern Atlantic Ocean Barotropic Rossby Waves
font style='font-size:12px;'>
2009/1/5
A dynamical model representing linear barotropic Rossby waves is combined with GEOSAT data from the northwest Atlantic Ocean. The model is too simple to be very realistic in this complex area, but the...
