Involved in understanding the variability of the Indian, Pacific and Southern oceans, from a climate dynamics point of view, which drive many regional climate extremes with potentially devastating impacts. Underneath this variability, the detection and attribution of climatic changes is also of interest, as is the response of the major modes of climate variability to climate change.

Research | Current

Assessing the impacts of changing summer characteristics and related extreme heat stress: Anthropogenic contribution and possible benefits of global warming mitigation goals.

The influence of climate variability on seasonal extremes over New Zealand and surrounds.

Influence of natural climate variability on the extreme ocean surface wave heights.
