- 22. PATTERNS DISTINCT FROM O-A MODES Exceptionally strong decadal or multidecadal behavior in terrestrial precipitation does not appear to be linearly related to the ‘usual suspects’ of major climate modes.
- 23. STRONG ≠ FORCED? Even for regions with exceptionally strong decadal patterns, we cannot rule out the possibility that this behavior is caused by processes with an underlying white spectrum.
