Solar heating of surface waters in the tropical Indian and Pacific oceans, along with turbulent mixing that moves this heat into the colder deep-reaching Atlantic meridional overturning circulation, play a crucial role in shaping oceanic heat transport pathways

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.

CLEX researchers investigate the physics of the Antarctic Circumpolar Current to understand why increased wind stress doesn't lead to a more powerful current. It turns out the ocean floor plays a key role.

To better understand the biases and ultimately improve the quality of our climate records, CLEX researches and their collaborators undertook in situ measurements using the NOAA Physical Sciences Division flux system during the Clouds, Aerosols, Precipitation, Radiation, and Atmospheric Composition over the Southern Ocean (CAPRICORN) experiment in 2016.

This study found in CMIP5 models that are able to simulate both types of events, that convective extremes do not always coincide with warm extremes. The disassociation becomes more distinct under greenhouse warming with higher occurrences of convective extremes than warm extremes.

This paper investigates the annual cycle in cloud and rainfall measurements over the western equatorial Indian Ocean. While there is a single period of strong rainfall over the region during December-January each year, there are two periods of increased high-top clouds associated with convection.

While the data from Himiwari-8 provides very useful data on clouds at relatively high resolution, researchers need to know if it produced any biases, particularly around cloud-top height and cloud-top temperature, whose roles are critical in shaping Earth’s climate. CLEX researchers and Australian colleagues compared the Himawari-8 data for both of these measures with existing datasets.

The energy of vortices in the Southern Ocean has increased over the past two decades due to an increase in the mean amplitude of the vortices rather than an increase in their number.

A known weakness of the Ensemble Kalman filter approach is that its ability to provide state estimates that closely match densely distributed observations is very limited. This paper describes a computationally inexpensive innovative variation on the technique that greatly ameliorates this difficulty.

A new study with Centre of Excellence researchers warns that changes in springtime winds high above the South Pole could trigger higher than usual heat waves and fire-prone weather conditions in Australia.
