(Also called climatic variability.) The temporal variations of the atmosphere– ocean system around a mean state.
Typically, this term is used for timescales longer than those associated with synoptic weather events (i.e., months to millennia and longer). The term "natural climate variability" is further used to identify climate variations that are not attributable to or influenced by any activity related to humans.
