long enough to average out the short - term noise, i.e. the chaotic sequences of «weather» events.
Given that the answer to this for atmospheric
models is a resounding «NO» (particularly because of sub-grid
scale processes which need to be effectively pre-ordained through parameterizations), and given that oceanic circulations have much
longer adjustment time
scales, yet also have much more intense small
scale (gyre) circulations than the atmosphere, my instinct is that we are not even close to being able to trust ocean
models without
long term validation data.
