Climate analogs

From Glossary of Meteorology

climate analogs

Information about past climates used as a projection of future climate.

Climate analogs generally take one of the following two forms:
  1. examination of climatic patterns of periods with a particular climate characteristic (e.g., warm periods) in the instrumental or paleoclimatic record;
  2. studies of groups of individual years or seasons, not necessarily consecutive, selected from the instrumental record for a particular characteristic.
