Abstract

Annual tree-ring chronologies from certain well-drained sites in the Hudson Valley of New York record past changes in temperature and precipitation. This information accounts for much of the July variation in Palmer drought severity indices during the period 1931 to 1970 and is used to develop a preliminary reconstruction of drought as long ago as 1728.

摘要

纽约哈德逊山谷某些排水良好的地点的年度树木年轮年表记录了过去温度和降水的变化。这些信息解释了 1931 年至 1970 年期间帕尔默干旱严重指数 7 月变化的大部分原因，并被用来对早在 1728 年的干旱情况进行初步重建。
