Project Description

Drought conditions and their frequency in the southeast U.S. are modulated by complex interactions of large-scale climate variations. To better understand the underlying mechanisms behind this relationship, researchers are employing reanalysis products to study drought conditions stemming from weather and climate variations over the past 50-100 years and performing fully coupled global simulations using the Community Earth System Model. Specifically, they are exploring the impacts of interdecadal Pacific oscillation and Atlantic multidecadal oscillation and the associated activity of El Niño–Southern Oscillation (ENSO) on drought. They will also consider how future changes in the state of the Pacific and Atlantic oceans might impact drought conditions and incorporate machine learning techniques to validate and test for projections of drought conditions. This model is a first attempt at predicting southeast U.S. drought exclusively through utilizing multidecadal teleconnection patterns with ENSO phase.
