Bio

Josephine Brown works on understanding past, present and future variability of climate in the Australian and Pacific region. Previous research has included palaeoclimate modelling studies of El Niño and monsoon variability since the Last Glacial Maximum. Her current research is focused on reducing uncertainty in regional rainfall projections over Australia. She obtained a PhD from the University of Melbourne in 2004, and then spent three years as a postdoctoral research fellow at the University of Reading (UK). She joined the Bureau of Meteorology in 2009.

The Bureau of Meteorology bom

The Bureau of Meteorology is Australia’s national weather, climate and water agency. The Bureau contributes to national social, economic, cultural and environmental goals by providing observational, meteorological, hydrological and oceanographic services and by undertaking research into science and environment related issues in support of its operations and services. The Bureau is involved in operational seasonal predictions and the development of longer (i.e. decadal) predictions. Long historical records and palaeoclimate data, such as those to be produced through the VicDRIP project, can provide a valuable benchmark to evaluate the predictive tools developed by the Bureau.
