Debbie Hudson

Principal Research Scientist

Current work and responsibilities

My research focuses on multi-week (sub-seasonal) and seasonal climate prediction. I am particularly interested in how forecast initialization and ensemble design affects forecast skill; the sources of multi-week predictability; the ability to predict extremes; forecast verification; developing forecast products and interfacing to applications. A key component of my work involves leading research and development projects and interacting with internal and external stakeholders.

I am heavily involved in the progression of the Bureau's seasonal forecast system and products from R&D into operations and services. I have developed and assessed aspects of the initialisation and ensemble generation schemes, which have been integral to successive system upgrades. I have led major externally funded multi-week prediction projects that have laid the foundation for the Bureau's movement into multi-week prediction and the prediction of extremes. I am currently involved in leading the development and verification of forecast products based on ACCESS-S, the Bureau's next generation seasonal prediction system.
