Аннотация: The purpose of the present study is to test critically the covariation of tree growth and rainfall-tree growth as measured by the thicknesses of growth layers on increment cores. There are two general conclusions. First, the evidence indicates rather clearly that variations in tree frowth follow variations of March-July rainfall from year to year very nearly 100% at the immediate site of the trees. Second, the evidence strongly suggests that changes of internal agreement among the trees and changes of average variation , average departure, and average departure from mean variation can be used as a method to reveal changes in rainfall through the years where amount of rainfall, and hence derived soil moisture, approximately equels that present at the location of the dominant members of the Holman Pass collection

Аннотация: The book deals with tree-rings which can be used as indicators of environment in conjunction not only with purely geologic studies but also with the principles of plant ecology as applied to plant remains of the past. Tree-ring studies in United States have served to emphasize the importance of rainfall in the year-to -year life of forest. Large areas of forest are independent of climatic fluctuations, among which rainfall stand high in importance. Solar radiation is one of the factors influencing climate and tree growth.
