PhD in "Nonlinearity and midlatitude low-frequency variability" Extratropical low-frequency variability is a topic of intensive research in many climate research centres because of its importance in understanding and improving predictability in weather and climate. The nature of this variability is a subject of ongoing debate between two mainstream, namely linear vs nonlinear paradigms. Recent research on the jet stream variability provides some evidence in support of the nonlinear paradigm in which extratropical low-frequency variability can be explained by low-order nonlinear dynamics. This entails, in particular, the existence of nonlinear circulation regimes, i.e. recurrent and quasi-stationary states of the extratropical large-scale flow. There is the possibility that these flow regimes may be associated with different states of the midlatitude jet stream, which could provide a key explanation of these circulation or weather regimes. This association can enhance the prediction of weather regimes, weather regimes transitions and ultimately may improve weather and climate predictability. A PhD student is sought to conduct research on this topic using simple and complex mathematical models of the atmosphere. Concepts and methods from dynamical system's theory and time series analysis will be used. Application: The successful applicant should have a MSc with an upper second class honour degree or above in mathematics, statistics, physics or atmospheric science. The candidate should show a keen interest in the application of mathematical/statistical methods to problems in weather and climate. Some experience in Matlab/Fortran programming is preferable.
