Abstract
We investigate the error growth, that is, the growth in the distance between two typical solutions of a weather model. Typically grows until it reaches a saturation value . We find two distinct broad log-linear regimes, one for below 2% of and the other for above. In each, grows as if satisfying a linear differential equation. When plotting vs , the graph is convex. We argue this behavior is quite different from other dynamics problems with saturation values, which yield concave graphs.
