Abstract

ABSTRACT This study reports two multi-century regional reconstructions of annual precipitation based on Pinus ponderosa and P. edulis from four sites in central northern Arizona. It compares standard regional and time-nested methods to generate reconstructions from 1581–2016 C.E. and 1529–2016 C.E., respectively. The strongest climate relationship is a positive correlation between total ring width and 12-month total precipitation ending in July of the growth year. The chronologies account for 50% of the variance of observed annual precipitation in the regional model and 59%, 60%, and 47% and 35% in the nested models. The two reconstructions are highly correlated (Pearson's correlation r > 0.97, p < 0.001) demonstrating that the reconstructions are highly similar over the period common to both reconstructions, with the nested-models’ advantage of extending the range of the reconstruction. The precipitation reconstructions are significantly correlated (r = 0.66, p < 0.001) with the North American Drought Atlas (NADA).

根据树木年轮对亚利桑那州中北部8 - 7月降水的两次重建

摘要:本研究报道了美国亚利桑那州中北部4个地点的黄松和毛竹的2个多世纪区域年降水量重建。它比较了标准的区域和时间嵌套方法，分别生成1581-2016年和1529-2016年的重建。环总宽度与生长期结束于7月的12个月总降水量呈显著正相关。在区域模式中，年表对年降水观测方差的贡献率为50%，在嵌套模式中为59%、60%、47%和35%。这两个重建是高度相关的(Pearson’s correlation r > 0.97, p < 0.001)，这表明重建在两个重建共同的时期内是高度相似的，嵌套模型的优势是扩展了重建的范围。降水重建结果与北美干旱图谱(NADA)呈显著相关(r = 0.66, p < 0.001)。

期刊介绍： Tree-Ring Research (TRR) is devoted to papers dealing with the growth rings of trees and the applications of tree-ring research in a wide variety of fields, including but not limited to archaeology, geology, ecology, hydrology, climatology, forestry, and botany. Papers involving research results, new techniques of data acquisition or analysis, and regional or subject-oriented reviews or syntheses are considered for publication. Scientific papers usually fall into two main categories. Articles should not exceed 5000 words, or approximately 20 double-spaced typewritten pages, including tables, references, and an abstract of 200 words or fewer. All manuscripts submitted as Articles are reviewed by at least two referees. Research Reports, which are usually reviewed by at least one outside referee, should not exceed 1500 words or include more than two figures. Research Reports address technical developments, describe well-documented but preliminary research results, or present findings for which the Article format is not appropriate. Book or monograph Reviews of 500 words or less are also considered. Other categories of papers are occasionally published. All papers are published only in English. Abstracts of the Articles or Reports may be printed in other languages if supplied by the author(s) with English translations.
