Teleconnection Patterns and S2S Predictability



Course Information

A joint initiative of the American Monsoon Working Group (WG-AMM) of the World Climate Research Programme (WCRP) and the Postgraduate Program in Environmental and Water Resources at the Federal University of Itajubá.

Responsible: Michelle Reboita (co-chair WG-AMM)

Course Objectives

The course aims to introduce the fundamental concepts of large-scale atmospheric patterns that influence the American Monsoons, providing participants with the background needed to develop subseasonal-to-seasonal (S2S) forecasts.
