Precipitation Variability in the Inter-tropical Andes - Climatological Studies for Paleoclimatic Reconstruction

ATM-9707698，雷蒙德·S·布拉德利，马萨诸塞州大学标题：热带安第斯山脉的降水变率--古气候重建的气候学研究本建议在年际-年代际尺度上研究大西洋海温与热带安第斯山脉降水的关系。将对安第斯山脉的同位素数据进行审查，以建立一个将环流变化与同位素变化联系起来的经验模型。安第斯山脉是重要的冰芯记录的所在地。这项研究将利用大西洋海温异常数据、南美洲热带高空数据、热带安第斯山脉沿线密集站点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，从而为了解那个遥远过去的气候条件提供一些线索。

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.
