Research Brief: Regional variations in projections of recent changes in the western boundary currents

November 24, 2021 12:44 pm Published by Comments Off on Research Brief: Regional variations in projections of recent changes in the western boundary currents

Strong ocean currents are found on the western side of the ocean basins, which flow from the tropics toward the poles in both hemispheres. These western boundary currents have shown strong changes in the last few decades, resulting in intensified ocean warming and are projected to amplify further in the future.

Research brief: Ekman Streamfunction a strong indicator of overturning circulation strength & variability

CLEX researchers used a state-of-the-art global ocean-sea-ice model to directly measure the overturning circulation, and through this to examine the relationship between the Ekman Streamfunction and the Southern Ocean overturning circulation.

Research brief: What drives extreme heat events in spring?

Maximum temperatures in Australia during spring have exceeded historic records on multiple occasions in recent years. Understanding what drives these high temperatures may lead to better forecasts of extreme heat in the future.

Research brief: Ring like structure in cyclone leads to rapid intensification of surface winds

March 5, 2021 11:19 am Published by Comments Off on Research brief: Ring like structure in cyclone leads to rapid intensification of surface winds

The most intense and destructive tropical cyclones generally go through a period of rapid intensification, where "rapid" means that the near-surface winds increase by more than 15 m/s (54km/hr) in 24 hrs. However, the physical processes by which storms rapidly intensify are not well understood. This study uses very high-resolution simulations with the UK Met Office Unified Model of the 2016 north-Pacific tropical cyclone, Nepartak, to explore the processes responsible for its rapid intensification.

Research brief: How warm water reaches Antarctica

May 2, 2020 4:00 am Published by Comments Off on Research brief: How warm water reaches Antarctica

Using a high-resolution ocean model, CLEX researchers unexpectedly found 80% of the transport in the warm water layer, known as Circumpolar Deep Water, approaches Antarctica in the colder regions.

Research brief: Simulating tropical cyclones with ACCESS

March 19, 2020 1:29 pm Published by Comments Off on Research brief: Simulating tropical cyclones with ACCESS

This two part paper examines the capacity of ACCESS to simulate tropical cyclone climatology and then used the same model to examine the relationship between climate variables and tropical cyclone formation.

Research brief: New model explores the relationship between humidity, instability, and precipitation in the tropics

November 26, 2019 9:57 am Published by Comments Off on Research brief: New model explores the relationship between humidity, instability, and precipitation in the tropics

In this paper, CLEX researchers considered the steady-state response of the atmosphere to an imposed large-scale flow. They found that under these steady-state conditions, humidity increases with the precipitation rate, while the lapse rate (rate of decrease of temperature with height) increases.
