| Abstract | The linear stability of a coastal transition zone (CTZ) jet is analyzed using a six-layer quasi-geostrophic model with observed basic state velocity profiles. The velocity profiles are obtained from objectively analyzed hydrographic and acoustic doppler data from the 1987 CTZ pilot experiment. Along-jet perturbation wave-lengths of 260-265 km are found to be the most unstable, with e-folding growth periods of 7-11 days and along-jet phase speeds of 4-8 km/d downstream. Energy transformation terms and energy budgets are discussed. Both barotropic and baroclinic instability processes are important. |
