Can the ocean’s intrinsic dynamics feedback on the atmosphere?

August 17, 2021 10:38 am Published by Comments Off on 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.

Developing and publishing open-source software and my experience with an open peer-review process

Navid Constantinou developed a new Julia package that provides solvers for geophysical fluid dynamics problems in periodic domains. It was also the first time he had been involved in an open peer-review process, and this experience was "mind changing".

Research brief: How magnetic fields can make water behave like honey

November 26, 2019 10:49 am Published by Comments Off on Research brief: How magnetic fields can make water behave like honey

Turning on a magnetic field may make fluids that conduct electricity behave more like honey than like water. This discovery may help explain a mystery of Jupiter's zonal winds, the alternating east-west jet streams, seen in photographs as colourful stripes.

Research brief: Southern Ocean vortices are changing

October 22, 2019 2:26 pm Published by Comments Off on Research brief: Southern Ocean vortices are changing

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.

Research brief: Magnetic Suppression of Zonal Flows on a Beta Plane

October 4, 2018 12:03 pm Published by 1 Comment

One of the most striking features of Jupiter –-a gaseous giant with no solid surface-- is the coloured bands encircling the planet. These bands are strong zonal jets that flow in Jupiter’s atmosphere, similar in a way to the jets in Earth's atmosphere. Until recently, we had almost no direct observations beneath Jupiter's clouds.
