PDRA in Physical Climate Change Science, University of Exeter
This NERC funded post is available immediately. You will be required to work as part of a wider team led by Prof Mat Collins, and collaborate closely with Dr Jennifer Catto and Prof James Screen. There are two scientific areas of interest. Both will use climate model output and observations to improve understanding of the drivers of (i) extreme weather in mid-latitudes and of their projected changes over the coming century or (ii) the role of changing spatial patterns of sea surface temperatures (SSTs) on tropical and subtropical rainfall.
The weather of the mid-latitudes, including the United Kingdom, is strongly influenced by the passage of low- and high-pressure weather systems. When these systems get stuck in one location for an unusually long time, or 'stall', the resulting extreme weather can have major societal impacts. Some studies suggest that rapid Arctic surface warming may increase the occurrence of stalled weather systems by slowing the midlatitude jet stream. However, tropical upper tropospheric warming could have an opposite effect, leading to a "tug-of-war" between Arctic and tropical influences. This sub-project seeks to investigate this tug-of-war and will include developing new metrics to measure the frequency and duration of stalled weather systems by considering the paths of individual cyclones in observations, and historical and future climate simulations.
Changes in precipitation in the tropics and sub-tropics are tightly coupled to areas of relatively warmer SSTs. The situation over land is more complex, with the mean state atmospheric circulation being important as well as evapotranspiration linked to the direct impact of CO2 on vegetation. This sub-project seeks to investigate the role of changing spatial patterns of SST on the atmospheric circulation and its link to changing rainfall patterns. There will be an initial focus on the Amazon region, but the techniques developed will also be applied throughout the tropics and subtropics.
The post is available now and will extend to 31 January 2022. It is part of two large NERC consortium projects 'Robust Spatial Projections of Real World Climate Change' and 'Emergence of Climate Hazards’.
You will be able to develop research objectives and make presentations at conferences and other events.
- possess a relevant PhD (or nearing completion) or equivalent qualification/experience in a related field of study
- possess sufficient specialist knowledge in the discipline to develop research programmes and methodologies
- be able to work collaboratively, supervise the work of others and act as team leader as required
- be able to manipulate complex climate model datasets, assess physical processes and prepare papers for publication in high quality journals.
The University of Exeter
With over 22,000 students and 5,500 staff from 180 different countries we offer a diverse and engaging environment in which to work. We are an equal opportunity employer, a Disability Confident employer and an Athena Swan accredited institution. Whilst all applicants will be judged on merit alone, we particularly welcome applications from groups currently underrepresented in the workforce.
We are a member of the prestigious Russell Group of research-intensive universities and in the top 150 universities in the world (Times Higher Education World University Rankings 2019). We combine world-class teaching with world-class research, achieving a Gold rating in the Teaching Excellence Framework Award 2017.
Our research income in recent years means we're fastest growing UK Research University and we seek to answer some of the most fundamental issues facing humankind today through this. 98% of our research is international quality (2014 Research Excellence Framework) and we encourage proactive engagement with industry, business and community partners to enhance the impact of research and education and improve the employability of our students. Exeter is the only UK city to have been designated as a UNESCO Creative City.
We offer some fantastic benefits including:
- 41 days leave per year
- options for flexible working
- onsite gyms on all of our campus' and a cycle to work scheme
- sector leading policies around maternity, adoption and shared parental leave (up to 26 weeks full pay), paternity leave (up to six weeks full pay) and a new Fertility Treatment Policy
- stunning campus environments in Exeter and Cornwall, in the beautiful South West of England
