About the Partnership

This project is one of a number that are in competition for funding from the NERC Great Western Four+ Doctoral Training Partnership (GW4+ DTP). The GW4+ DTP consists of the Great Western Four alliance of the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five Research Organisation partners: British Antarctic Survey, British Geological Survey, Centre for Ecology and Hydrology,  the Natural History Museum and Plymouth Marine Laboratory. The partnership aims to provide a broad training in earth and environmental sciences, designed to train tomorrow’s leaders in earth and environmental science.

Project Background:

The main energy input for the Earth climate system is the Sun. The effect of fluctuations in its energy output, such as short-term solar flares or the 11-year solar cycle, are not well understood in modern regional and decadal climate projections. Solar activity is also the main factor in space weather prediction, which is critical for mitigating disruptions in satellite communications and space exploration. Correct coupling of the lower atmosphere to the upper atmosphere is an unsolved problem, requiring novel modelling approaches. How is Earth’s climate affected by the solar activity? What are the effects in the neutral photochemistry, ion chemistry, and the direct radiative heating of the upper atmosphere? What is the complexity required of the atmospheric models to reproduce the effect of solar activity? These are the main questions motivating this project. The project will focus on extending the Met Office Weather and Climate model (the UM and, progress permitting the next-generation model, LFRic) into the mesosphere and lower thermosphere, with the addition of physical processes to represent photochemistry and energetic particles. The outcome of the project will be a whole atmosphere model able to simulate the top-down mechanisms of the stellar influence on the surface climate, as well as the bottom-up mechanisms important for space weather models. Beyond Earth applications, this project will have important implications for the solar system and exoplanet research.

Project Aims and Methods:

The aim of the project is to determine which aspects of external forcing induced by solar variability have a significant effect on surface climate. In addition, we will investigate what forcing (e.g., gravity waves) should be included in the space weather prediction models. The methodology will consist of the development of the extended atmosphere model, including implementation of the required neutral and ion photochemistry, and validation of the model against observed climatologies and case studies of specific solar events. This will build on the recent progress made in improving the representation of the radiative transfer and photochemistry in the Met Office models. Importantly, the student will have the opportunity to shape the direction the project and bring in their own ideas. For example, they can choose to focus more on the top-down or bottom-up aspects of the atmosphere interaction.
