Research & Current Projects


RESEARCH INTERESTS

Andrea investigates the mechanisms by which the oceans can affect the climate through numerical models. She is interested in climate variability, teleconnection patterns in the Southern Hemisphere, air-sea interactions and statistical methods for data analysis. Her work look sat the impact of global sea surface temperature variability on regional precipitation over Australia and South America. She is particular interested in the mechanisms of the different types of El Nino Southern Oscillation and how these influence atmospheric circulation and interact with other oceanic basins.

CURRENT PROJECTS

ARC Discovery Project:Modes of Pacific Ocean variability and their relationship to regional Southern Hemisphere climate”, lead CI and APD. This project explores how the Pacific modes of variability, such as the El Niño-Southern Oscillation, drive climate variability over Australia and other Southern Hemisphere regions using observations and climate model experiments.
