Fast singular oscillating limits and global regularity for the 3D primitive equations of geophysics
Fast Singular Oscillating Limits and Global Regularity for the 3D Primitive Equations of Geophysics
Fast singular oscillating limits of the three-dimensional "primitive" equations of geophysical fluid flows are analyzed. We prove existence on infinite time intervals of regular solutions to the 3D "primitive" Navier-Stokes equations for strong stratification (large stratification parameter N). This uniform existence is proven for periodic or stress-free boundary conditions for all domain aspect ratios, including the case of three wave resonances which yield nonlinear " dimensional" limit equations...
