A top - down
climate effect that shows long - term drift (and may also be out of phase with the bottom - up solar forcing) would change the spatial response patterns and would mean that
climate - chemistry
models that have sufficient resolution in the stratosphere would
become very important for making accurate
regional / seasonal
climate predictions.
In terms of longer timescales (decadal to century), once the focus
becomes regional rather than global, historical and paleo data
becomes more useful than global
climate model simulations (no matter what type of «right - scaling» methods are attempted).
