dendrochronology

The analysis of the annual growth rings of trees, leading to the calculation of significant indices of climate and general chronology of the past.

The width of a tree ring was determined by the temperature and/or the moisture that prevailed during the year of its formation. Since stress from temperature and/or moisture variations reduces the width of the seasonal growth of a tree ring, dendrochronology has important application in the study of long-term climatic variations.
