Dr. Martin Singh Research Projects

Dr Singh is a Chief investigator of the Centre of Excellence for Weather in the 21st Century, a multi-institutional collaboration focussed on understanding how climate change affects the weather. These projects will contribute to the research aims of the centre, and will allow students to be part of the Centre’s vibrant research community.

Midlatitude weather systems in a warmer climate

As the world warms, the moisture content of the atmosphere increases, causing changes to the dynamics of weather systems. In this project, we will investigate how these changes affect rainfall in the midlatitudes, using a high-resolution atmospheric model. By simulating midlatitude weather in idealised warmer worlds, we will investigate how changes in surface temperature and temperature gradients influence large-scale midlatitude weather patterns and the weather systems, such as fronts and cyclones, embedded within them that ultimately produce rainfall.

A theory for the vertical structure of tropical atmospheric circulations

The tropics is home to a variety of overturning circulations, some deep that span the troposphere, and some shallow that only reach a few kilometres above the surface. The precise mix of deep and shallow circulations strongly influences the distribution of precipitation and energy transport in the tropics, but there is no theory for what sets this mix. In this project, we will build on recent theoretical advancements to understand the physical factors that control the vertical structure of the tropical circulation, leveraging idealised modelling using both storm resolving and general circulation models.

A recipe for the Australian Monsoon

Variability of the Australian monsoon, its long term observed trends, and its future projections with climate change are all poorly understood at present. In this project we propose to investigate key processes that influence variations in the monsoon at all time scales, with an emphasis on idealised model simulations using ACCESS. Assessment of those processes in climate models may improve our understanding of future projections.
