FIGURE CAPTIONS

Streamfunction at t=12 (nondimensional time units, roughly 4 days) taken from simulation of a linear baroclinic wave interacting with topography extended in the north-south direction (y), and gaussian in the east-west direction (x). Shading indicates region within one half-width of the peak (maximum height is 0.5, corresponding to about 1.5 km in dimensional terms). Panels show (a) normal mode baroclinic wave, unmodified by topography; (b) first order correction for topography; (c) total streamfunction through first order; (d) second order correction for topography; (e) total streamfunction through second order; (f) the sum of the first two terms of the perturbation series; (g) the full solution with topography and (h) the total topographic perturbation. The degree of similarity between (f) and (h) indicates how well the series is converging.. Click on the size of the file below to view it.
