Increasing
zonal asymmetry in tropical precipitation is projected by 2100, with increases over Asian and African forests and decreases over South American forests.
By contrast, spring has weakly positive pressure trends over the continent and strong
zonal asymmetry in the Southern Ocean.
Will this introduce some numerical
zonal asymmetry if the ocean flux is imposed on this grid even though the flux formula is only latitude dependent?
The atmospheric circulation of a planet that has
no zonal asymmetries in boundary conditions will remain axisymmetric if the initial condition is.
However, the time scale of jet variation drops and nearly all sensitivity to parameters is lost when
zonal asymmetries, in the form of topography and thermal perturbations that approximate land — sea contrast, are introduced.

Although tropical precipitation change remains uncertain, nearly all models from the Coupled Model Intercomparison Project Phase 5 predict a strengthening
zonal precipitation
asymmetry by 2100, with relative increases over Asian and African tropical forests and decreases over South American forests.
