Summary

We construct the initial disturbances to be used in the subsequent simulations of surface fronts with generic 2D models. One version of the model has the Eady flow as its reference state. We go over a complete modal instability analysis of this basic flow, present all of its instability properties and discuss the essence of this instability. The other version of the model has a modified but equivalent basic state of the Charney model (e-Charney model). A corresponding instability analysis is presented. These materials are pedagogically interesting in their own right.
