Research brief: Inexpensive innovation improves Ensemble Kalman filter

October 22, 2019 1:42 pm Published by Comments Off on Research brief: Inexpensive innovation improves Ensemble Kalman filter

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.

Research brief: Do wet soils affect rainfall?

How wet the soil is before a storm can determine the amount of rain that falls. This research also produced some interesting findings for rainfall in Australia.

UNSW3: Understanding the vertical mixing of water vapour

August 14, 2018 4:49 pm Published by Comments Off on UNSW3: Understanding the vertical mixing of water vapour

In this project, we seek to utilise 40 years of observations of water vapour profiles from the global radiosonde network to improve our process level understanding of water vapour mixing. The applicant is expected to know the basics of atmospheric physics and statistics. Some knowledge of data processing tools will be an advantage.

UNSW2: Mixed teleconnection – complex pathways linking ENSO to remote parts of the world

August 14, 2018 4:39 pm Published by Comments Off on UNSW2: Mixed teleconnection – complex pathways linking ENSO to remote parts of the world

This project will examine ‘mixed teleconnections’ using coupled climate models. In particular, we will examine how El Nino and La Nina events can affect western boundary currents in the Pacific and Indian basin. It will involve using large model and observational datasets and require a background in either MATLAB or python. Some experience with linux is desirable.
