Andrew Marshall

Senior Research Scientist

Current work and responsibilities

Subseasonal to interannual variability of the atmosphere-ocean climate system and its role in weather and climate prediction, with particular specialisation in drivers of global weather and climate variability and extremes including:

• - Madden-Julian Oscillation
• - El Nino Southern Oscillation
• - Quasi-Biennial Oscillation
• - Indian Ocean Dipole
• - Annular Modes
• - Blocking
• - Monsoons
• - Stratospheric Sudden Warmings

Leadership of Bureau project work on ACCESS-S development, subseasonal to seasonal prediction skill, and marine and terrestrial heatwaves.

Development of realtime trial forecast products for research use and display on the POAMA website:

• Heatwave probabilities
• Madden-Julian Oscillation
• MJO probabilistic
• Integrated climate drivers
• Australian and Indian monsoon indices
