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.

Project Description:

Forecasts produced by fluid-dynamical models of the atmosphere are often inaccurate due to simplifications and approximations in the numerical implementation, or due to the sparseness of the observational data. A statistical post-processing step, in which past forecast errors are learned and subsequently corrected, can significantly improve the performance of weather forecasts. In this project, the candidate will study and develop spatio-temporal statistical models for forecast post-processing, that correct forecast errors by taking advantage of the rich correlation structure in space and time of forecasts, observations, and their inter-dependency. Bayesian methodology will be used to quantify and propagate all uncertainties, e.g. due to observational errors and limited training data. The success of the newly developed methodology will be assessed by suitable forecast verification metrics for spatially extended forecasts of temperature and precipitation fields in a number of different study areas. During the PhD, the candidate will learn advanced statistical modelling tools in an applied context and benefit from the strong links between the University of Exeter and the UK Met Office.

Entry requirements

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 an appropriate area of science or technology. 

The degree should be in Statistics, Mathematics, or a suitable equivalent.

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/).

How to apply

In the application process you will be asked to upload several documents.  Please note our preferred format is PDF, each file named with your surname and the name of the document, eg. “Smith – CV.pdf”, “Smith – Cover Letter.pdf”, “Smith – Transcript.pdf”.

• CV
• Letter of application (outlining your academic interests, prior project work experience and reasons for
  wishing to undertake the project).
• Transcript(s) giving full details of subjects studied and grades/marks obtained (this should be an
   interim transcript if you are still studying)
• Two references from referees familiar with your academic work. If your referees prefer, they can email
   the reference direct to pgrenquiries@exeter.ac.uk quoting the studentship reference number.
• If you are not a national of a majority English-speaking country you will need to submit evidence of your proficiency in English.  Please see the entry requirements information above.

The closing date for applications is midnight on 10th January 2022.  Interviews will be held online on the week commencing 24th January 2022.
