High Resolution Hydroclimate Variability in the Central Andes of Chile and Argentina reconstructed by ancient Austrocedrus chilensis

Content

The highly waterdependent semiarid Andes of Chile and Argentina (CChA) are characterized by extremely variable annual precipitation regimes. The existing hydroclimate instrumental records from CChA provide a spatially dense network but only for the last 40-80 years. During recent decades our tree-ring studies in Austrocedrus chilensis have demonstrated the usefulness of this conifer to reconstruct hidroclimate variability in the CChA over several centuries. We will present a starting project were we propose to develop a millennium-long reconstructions of combined hydroclimate variables for the CChA. Our goals are to characterize the main temporal patterns of these reconstructions at different time-scales, and investigate the hindcast skill of downscaled climate products based on the current generation of General Circulation Models by comparing tree-ring based hydroclimatic reconstructions with simulated regional climates of the past millennium.
