Abstract
The nonlinear development of the Batchelor-Nitsche instability (of a p eriodically stratified fluid) is considered, utilizing the disparity b etween vertical and horizontal scales of motion. The resulting evoluti on equation is used to show that the preferred pattern of convection t akes the form of rolls, and that the motion evolves to larger and larg er horizontal scales as time increases.
