Description :
Analysis of the annual summation of rainfall in excess of 100 mm/day shows that the rainfall in this area has dominant periodicities of about 25-30, 10-13, and 5-7 years. The period 25-30 years corresponds to that of occurrence of the natural disasters produced by heavy rainfall. Analyses of tree ring width from these mountains indicate that the sequences have a dominant periodicity of about 25-30 years. Cross-spectral analyses for rainfall and ring width in this area show high coherency for the periods of about 25-30 years| evidence that variations in the ring width may be used as proxy data for erosional force.
