Dynamical Balance in the Initial Conditions

Dynamical Balance in the Initial Conditions 12 December 2012

Thematic Outline of Basic Concepts • Why is it important to initialize a model with appropriately balanced initial conditions? • What is geostrophic adjustment, and how is it relevant to dynamical balance in the initial conditions? • What are some means by which dynamical balance can be achieved, and how are they formulated?
