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.马萨诸塞大学的标题：热带跨气层安第斯山脉中的降水性变异性 - 古气候重建的气候研究该建议OS研究大西洋SST与二十年二十年际时尺度上跨热带和人类的降水之间的关系。 将检查安第斯山脉（Andes）上回收重要的冰核记录的同位素数据，以开发一个经验模型，该模型将循环变化与同位素变化有关。 这项研究将利用大西洋SST异常数据，热带南美洲的高空数据，来自热带安第斯山脉沿线密集的站点网络的降水数据以及稳定的同位素数据。 这项研究将有助于解释热带冰芯的全新世气候记录，从而对遥远的过去的气候条件有所了解。
