We are pleased to be convening the session “Assessing Regional Climate Signals From Southern South America: Modern and Paleo Efforts” at the upcoming AGU Fall Meeting 2018

Dear colleagues,

We are pleased to be convening the session “Assessing Regional Climate Signals From Southern South America: Modern and Paleo Efforts” at the upcoming AGU Fall Meeting 2018 held on 10-14 of December in Washington D.C., USA. Please consider contributing an abstract to this session at the AGU website (https://fallmeeting.agu.org/2018/welcome/) by the deadline of Wednesday, 1 August 23:59 EDT, 2018. We would be very thankful if you would circulate this session to your colleagues and students. Please don’t hesitate to contact us if you have any further question.

Looking forward to seeing you all in Washington DC,

Sergio Contreras (scontreras@ucsc.cl)

The influence of the Southern Hemisphere Westerly Winds (SWW) on the modern climate of Southern South America [SSA] (south of 30°S) is well known. The SWW, in combination with the N-S orientation of the Andes, are responsible for vegetation gradients with latitude and elevation, which likely varied in the past as a function of the strength and location of the SWW. Models project a poleward shift and intensification of the SWW as a result of global warming, superimposed on natural climate variability that is less well understood in this vast area with sparce meteorological data. Thus, we need to turn to paleoclimate proxy records to gather data on climate variability and help validate future climate projections in the region. This session invites researchers in diverse fields, including proxy development and modeling using marine and continental records, to examine modern and past climate in SSA.
