Abstract: | Climatic fluctuation is a serious problem for forestry in Lapland. Some indications about the nature and causal relationships of such fluctuation have been discussed. Cyclic variation can be explained by a memory in the atmosphere, variation in the Moons's gravitation, and solar activity. The index of atmospheric circulation over the northern hemisphere was the most effective climatic parameter in explaining the growth variation of Scots pine. |
