The University of Exeter’s College of Engineering, Mathematics and Physical Sciences is inviting applications for a fully-funded PhD studentship to commence in January 2022 or as soon as possible thereafter. The studentship will cover Home tuition fees plus an annual tax-free stipend of at least £15,609 for 3.5 years full-time, or pro rata for part-time study.
This College studentship is open to UK and Irish nationals, who if successful in their application will receive a full studentship including payment of university tuition fees at the home fees rate.
Comprehensive numerical global climate models (GCMs) are used to make projections of changes in 21st century climate. Because many model simulated processes are uncertain, GCMs produce a wide range of different but physically plausible 21st century predictions. The largest uncertainty in GCM predictions of future global temperature has been traced to tropical low-level cloud feedbacks. Recent work suggests that the strength of these feedbacks is linked by the tropical circulation to remote deep atmospheric convection associated with large thunderstorms .
This project will seek to understand the causal mechanisms underlying this cloud-circulation coupling link and to quantify the extent to which they contribute to inter-model differences in cloud feedback, and future projections of tropical precipitation and global surface temperature.
The project will use GCM simulations to understand how the effects of heating and moistening perturbations in different parts of the tropical atmosphere affect rainfall and cloud. By linking the perturbations to uncertainty in model-simulated processes in the relevant parts of the atmosphere, we will aim to understand not only how cloud feedback and the hydrological cycle are linked, but also the cause of spread in model simulated feedbacks and precipitation.
This PhD forms part of the CIRCULATES project, which seeks to constrain our uncertainty in future cloud feedbacks and climate change. CIRCULATES is a national consortium of universities and research institutes led by Exeter. The PhD student will have the opportunity to interact not only with researchers at Exeter, but also those at St Andrews, Imperial College, Reading, the Met Office, The Rutherford Appleton Laboratory and the U.K Centre for Ecology and Hydrology. A particular benefit will be the opportunity to collaborate with researchers using high-resolution models that, although unable to model the whole atmosphere, are better able to capture physical processes.
This studentship is open to UK and Irish nationals, who if successful in their application will receive a full studentship including payment of university tuition fees at the home fees rate.
Applicants for this studentship must have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK, in Mathematics, Physical Sciences, Meteorology, Environmental Sciences or a related area.
If English is not your first language you will need to have achieved at least 6.0 in IELTS and no less than 6.0 in any section by the start of the project.
Alternative tests may be acceptable (see http://www.exeter.ac.uk/postgraduate/apply/english/).
