Biography

Dr Wenju Cai, a Chief Research Scientist, an Office of Chief Executive Science Leader at CSIRO, and Director of Southern Hemisphere Oceans Research, specialises in research into global climate variability and change. With over 25 years of research and leadership experience, his interest spans from dynamics of modes of climate variability (such as El Niño-Southern Oscillation and the Indian Ocean Dipole) and their mechanisms, to climate change detection and attribution, through to impacts of individual forcing factors of increasing carbon dioxide, increasing anthropogenic aerosols, and stratospheric ozone depletion. His sustained science achievement has had major influence on research directions of a large body of work. His service to science communities includes a contributing authorship to IPCC reports, co-Chair of World Climate Research Programme CLIVAR Pacific Panel during 2009 – 2015, a member of the CLIVAR Scientific Steering Group (2016-2018) and its co-Chair (2019-ongoing). He specialises in conceptual nonlinear frameworks for extreme El Niño and extreme La Niña, and the IOD, uncovering nonlinearity in the dynamics and impact. These have resulted in the projection of increased frequency of these extremes under greenhouse warming. Cai has elucidated the dynamics of major modes of Southern Hemisphere ocean-atmosphere variability and change, including the role of Antarctic ozone depletion, increasing CO2 and the associated ocean circulation changes. In 2020, Cai was elected as Fellow of the Australian Academy Science.
