Discovery of the 5.7-Year Douglass Cycle: A Pioneer’s Quest for Solar Cycles in Tree-Ring Records
The astronomer A.E. Douglass is generally recognized as the founding father of dendrochronology. He studied tree rings in the search for evidence that solar variation (as seen in sunspots) is reflected in climate variation. He was convinced that his quest was successful. Analysis of some of his early data using Fourier decomposition and comparison of tree-ring periodograms with those based on k...
متن کاملTree-ring isotope records of tropical cyclone activity.
The destruction wrought by North Atlantic hurricanes in 2004 and 2005 dramatically emphasizes the need for better understanding of tropical cyclone activity apart from the records provided by meteorological data and historical documentation. We present a 220-year record of oxygen isotope values of alpha-cellulose in longleaf pine tree rings that preserves anomalously low isotope values in the l...
متن کاملStatistical Evidences in Type-II Censored Data
In this article, we use a measure of expected true evidence for determine the required sample size in type-II censored experiments for obtaining statistical evidence in favor of one hypothesis about the exponential mean against another.
متن کاملNEW RECORDS OF FORM-GENUS CYTOSPORA IN IRAN (II)
In a taxonomic study on form-species of form-genus Cytospora, about four hundred fungal specimens were collected from all over the Iran during 2003-2005. In this paper, the second part of the obtained results, including seven form-species are presented. Cytospora intermedia, C. kantschavelii, C. leucosperma and C. ribis are reported as new members for mycoflora of Iran. Salix aegyptiaca for C. ...
متن کاملMillennia-long Tree-ring Chronologies as Records of Climate Variability in Finland
There have been great advances in the field of dendroclimatological research during the past decades. Tree-ring data have been used to derive various climate variables for certain localities and for larger regions. Characteristics of tree-rings provide measurements which can be used as records of climate variability prior to any instrumental weather observations. This is how dendroclimatology c...
