Diagnostic Studies of Growing Season Rainfall Fluctuations in Central North America

这个为期三年的研究项目旨在扩大和拓宽 一个处理生长季节（五月至八月）的计划 落基山脉和阿巴拉契亚山脉之间地区的降雨量 山脉，墨西哥湾沿岸，加拿大约55 N。 的 迄今为止的基本目标是：（一）确定 1949- 2000年降雨量变化的特征空间格局 80;及（ii）量化“本地”气候系统 过程/条件（发生在研究之上和附近的过程/条件） 区域--水汽发生和供应，对流层 倾向于提供隆起）有助于对比 降雨模式的三个案例研究年（1975年，1976年，1979年）。 这些方案将（a）扩大和补充上述 降雨分析;（B）完成并整合上述“当地” 个案研究调查;及（c）展开调查 更广泛的气候系统导致该地区的生长季节 降雨量变化 这项研究很重要，因为它试图了解 全球气候变化背景下的区域气候变率 气候特征和强迫。

This three-year research project seeks to extend and broaden a program that is dealing with the growing season (May-August) rainfall of the region bounded by the Rocky and Appalachian mountains, the Gulf Coast, and approximately 55 N in Canada. The fundamental goals to date have been to: (i) identify the characteristic spatial patterns of rainfall variation for 1949- 80; and (ii) quantify the "local" climate system processes/conditions (those occurring over and adjacent to study region -- water vapor occurrence and supply, troposphere's predisposition to provide uplift) contributing to the contrasting rainfall patterns of three case study years (1975, 1976, 1979). The PIs will (a) extend and complement the aforementioned rainfall analyses; (b) complete and integrate the above "local" case study investigations; and (c) initiate inquiry into the wider climate system causes of the region's growing season rainfall variations. This research is important because it seeks to understand regional climate variability in the context of more global climate features and forcing.
