Abstract ATM-9707698 Bradley, Raymond S. University of Massachusetts Title: Precipitation Variability in the Inter-tropical Andes - Climatological Studies for Paleoclimatic Reconstruction This proposal os to study relationships between Atlantic SST and the precipitation in the inter-tropical Andes on the inter-annual- decadal time scales. Isotopes data over the Andes, where important ice core records were recovered, will be examined to develop an empirical model relating circulation changes to isotopic variations. This study will utilize Atlantic SST anomalies data, upper air data over tropical South America, precipitation data from a dense network of stations along the tropical Andean range, and stable isotope data. This research will help interpreting Holocene climatic record of tropical ice cores and will thus throw some light on the climatic conditions in that distant past.

摘要 ATM-9707698 Bradley, Raymond S. 马萨诸塞大学 标题：热带安第斯山脉降水变化 - 古气候重建的气候学研究 该提案旨在研究大西洋海温与热带安第斯山脉降水之间的关系年度-十年时间尺度。 安第斯山脉上空的同位素数据（在那里恢复了重要的冰芯记录）将被检查，以开发一个将环流变化与同位素变化联系起来的经验模型。 这项研究将利用大西洋海温异常数据、热带南美洲的高空数据、热带安第斯山脉沿线密集站网络的降水数据以及稳定同位素数据。 这项研究将有助于解释热带冰芯的全新世气候记录，从而为了解遥远过去的气候条件提供一些线索。
