Can the ocean’s intrinsic dynamics feedback on the atmosphere?
The ocean’s much larger heat capacity acts as “memory” suppressing the atmosphere’s “high-frequency variability” (over time scales of weeks) while producing oceanic motions that vary over longer time scales. This paradigm aims to explain how low-frequency variability emerges in the ocean. But, recently, this paradigm has been challenged.

Research brief: Evapotranspiration shows an increasing trend since 1980
Climate change is affecting the amount of water evaporating (from soils and surfaces) and transpiring (evaporating through plant leaves) from the land surface. Trends derived from DOLCE V3 show clear increases in ET since 1980 over the majority of the Earth’s surface.

Research brief: Climate change may increase hazelnut yield in Southeast Australia
CLEX researchers and colleagues combined high-resolution regional climate projections with a process-based hazelnut simulation model to predict future hazelnut yield in Australia.

Research brief: Urban heat island effect amplifies Sydney heatwaves
This research uses Sydney, Australia’s largest city, as a test case for our new configuration of the Weather and Research Forecasting model run at a very high resolution of 800 m with a new urban classification scheme that describes the complexity of Sydney’s built environment.

Research brief: How ENSO affects the North Atlantic
In this study, CLEX researchers and colleagues showed that the North Atlantic sea-surface temperature response to ENSO is nonlinear with respect to the strength of the sea-surface temperature forcing in the tropical Pacific.

Research brief: How cumulus convection changes with extreme rainfall
CLEX researchers used data from a wind profiler radar pair at Darwin, Australia, to determine the characteristics of individual up- and downdrafts observed at the site. They found updrafts with 5km vertical heights with extreme rain rates.

Research brief: The rare event that amplified the dry Australian spring of 2019 is unlikely to happen again
An unusual southern stratospheric warming event amplified the conditions that led to the Black Summer bushfires of 2019/20. CLEX researchers explored how frequently these rare warming events may occur with climate change.
