Biography

As a first year research scientist Leighton is conducting exciting and novel research into the role of uncertainty in anthropogenic emissions and the associated radiative forcing of global mean surface temperatures on the decadal scale. Leighton is currently employed as a researcher on the NERC funded SMURPHS project (https://www.smurphs.leeds.ac.uk). Having an interest in statistical methods, Leighton conducted research into the climatic importance of uncertainty in historical aerosol emissions during his PhD. With a decade of experience in secondary education Leighton continues to show an interest in teaching and learning.

Research Interests

  • Modeling atmospheric aerosols and the climatic effects of the associated radiative forcing.
  • Quantifying contributions to variance in model output from uncertain parameters

Leighton Regayre's research highlights the benefits of using sophisticated statistical tools to perform sensitivity analysis experiments. By understanding and quantifying contributions to variance in aerosol radiative forcing at the global and regional scales, Leighton has identified specific priorities for development in global climate models so as to reduce uncertainty in aerosol radiative forcing. The Global Model of Aerosol Processes (GLOMAP) is a major advance on previous global models and has been used to study a wide range of aerosol processes in the atmosphere, including new particle formation, marine aerosol, dust emission and transport, and cloud condensation nuclei. GLOMAP is also being used in the U.K. Hadley Centre Met Office's Earth System model (UK-ESM1) to study the interactions between aerosols, the oceans and the biosphere. Leighton has broadened his interest in radiative forcing uncertainty to include uncertainty in the climatic effects of changing emissions of greenhouse gasses and stratospheric volcanic aerosols on the decadal and multi-decadal scale.

Teaching Interests

Leighton has over a decade of experience in secondary Mathematics education, including leading teams of educators. At the University of Leeds he has demonstrated on Applied Mathematics and Statistics courses within the School of Earth and Environment and the School of Mathematics. Leighton has a particular interest increating experiences which elicit deep, long-term learning.

Project outline

The central aim of the research is to better understand the causes of periods where the rate of global-mean surface temperature is increased or decreased at decadal time-scales compared with long term (multi-decadal) trends. The multi-disciplinary research team are seeking to understand both the slowdown in the rate of warming since the late 1990s and also earlier hiatus and surge events.
