Project background

Wildfires in the seasonally dry forests of western North America, Australia, and the Mediterranean have had record-breaking impacts on livelihoods, economies, ecosystems, and even carbon storage in recent years.

Lightning strikes have been implicated as a major ignition source in these regions, however limited observations of lightning have until now restricted the assessment of relationships between lightning and wildfire in a changing climate. Consequently, the potential impact of climate change on wildfire ignitions by lightning are poorly understood.

Wildfire ignitions occur disproportionately during extremely hot and dry conditions, when vegetation is at its driest and most flammable. Such fire-prone weather conditions are becoming more frequent globally due to climate change.

Moreover, global warming might also promote increases in lightning frequency over land. Consequently, climate change presents compound risks of wildfire occurrence by enhancing both forest flammability and ignition opportunities.

This project will use observations to unravel the contribution of lightning ignitions to modern wildfire patterns in seasonally dry forests, and subsequently employ climate model projections to evaluate the impact of future climate change on lightning ignitions.

The project will improve understanding of how wildfire risks may change across the world’s forests in future, with the view to help society prepare and adapt to changing risks and to optimise the planning of climate-smart and fire-smart re/afforestation programmes.

Research Methodology

With the support of a international supervisory team, the student will:

  • identify lightning-ignited wildfires by combining observations of lightning and fire from satellites and ground-based sensors.
  • evaluate the regional impact of lightning strikes on spatial and temporal patterns of wildfire.
  • examine the climatic thresholds that determine whether lightning ignites wildfires.
  • predict future changes in wildfire risk resulting from compound increases in extreme weather and lightning, based on climate model projections.

Training

  • Programming with Python/R (advanced level): data analysis, machine learning, geospatial analysis.
  • NCAS climate modelling summer school (https://ncas.ac.uk/study-with-us/climate-modelling-summer-school/).
  • Overseas visits to co-supervisors in California (2 months) and Amsterdam (1 month).
  • Visits to the UK Met Office to interact with fire and lightning modellers.
  • Support to present at international conferences and submit findings to academic journals.

Person Specification

  • Degree or international equivalent in any quantitative or natural sciences discipline (e.g. Physics, Mathematics, Computer Science, Environmental Sciences, Meteorology, Chemistry).
  • Skills: Experience of using programming languages (e.g. Python or R) to analyse scientific data is desirable.

Key Information

  • This project has been shortlisted for funding by the ARIES NERC DTP and will start on 1st October 2023. The closing date for applications is 23:59 on 11th January 2023.
  • Successful candidates who meet UKRI’s eligibility criteria will be awarded a NERC studentship, which covers fees, stipend (£17,668 p.a. for 2022/23) and research funding. International applicants are eligible for fully-funded ARIES studentships including fees. Please note however that ARIES funding does not cover additional costs associated with relocation to, and living in, the UK.
  • ARIES students benefit from bespoke graduate training and ARIES provides £2,500 to every student for access to external training, travel and conferences, on top of all Research Costs associated with the project. Excellent applicants from quantitative disciplines with limited experience in environmental sciences may be considered for an additional 3-month stipend to take advanced-level courses.
  • ARIES is committed to equality, diversity, widening participation and inclusion in all areas of its operation. We encourage enquiries and applications from all sections of the community regardless of gender, ethnicity, disability, age, sexual orientation and transgender status. Academic qualifications are considered alongside non-academic experience, and our recruitment process considers potential with the same weighting as past experience.
