Abstract

The objective of this project is to implement and develop the methodology, initially built within the scope of the project 2014 / 14229-2, in order to establish and characterize the complex network of climate interaction between the Amazon region and its possible influence systems. The improvement of the investigative framework will allow to quantify the recent anomalous behavior related to precipitation in the Amazon and Southeast of Brazil, as well as provide a tool for characterizing and understanding the underlying dynamics governing these phenomena. The complex network will be built using tools that are state of the art in information theory techniques and probabilistic graphical models. The realization of this project will help to understand the non-linear and chaotic dynamics with spatial distribution described in the project 2014 / 14229-2. To achieve this goal we rely on the expertise of the researchers of the institution to be visited, which is our partner in the thematic project 2011 / 50151-0. (AU)
