Head of group

Dann Mitchell (Professor of Climate Science and Met Office Chair in Climate Hazards)

In 2016 I joined the University of Bristol faculty and established the Bristol Climate Dynamics group. Before joining Bristol I undertook 4 years of postdoctoral research in the University of Oxford’s Department of Physics (AOPP), having already completed a PhD in the University of Reading’s Meteorology department.

At Bristol, I hold the Met Office Chair in Climate Hazards, and coordinate the partnership between our two institutes. My research interests are focussed around weather and climate extremes, and how they impact society. I look into the future at climate projections, but also into the past, at climate attribution. My research starts with atmospheric circulation patterns, especially those relating to extreme weather, and ends with impacts. I have a strong focus on climate and health, for instance the health hazards from, heatwaves, flooding, or tropical cyclones. I also like to dabble in the atmospheres of other planets, especially Mars.

Rachel James (Senior Lecturer in Climate Science, UKRI Future Leaders Fellow)

My research focuses on African climate systems. I’m trying to find out more about how climate is changing now, and what further changes we can expect in the coming years and decades. This work is designed to inform climate change policy and planning. Before joining Bristol in 2020, I worked at University of Oxford and University of Cape Town. I’ve recently been awarded a UKRI Future Leaders Fellowship, and over the next 4-7 years I’ll be working with my team to improve climate information for climate change adaptation, bringing together new climate science analysis with insights from psychology and risk communication.

Peter Watson (Senior Lecturer, NERC Independent Research Fellow)

The main focus of my work is understanding the risks posed to society by extreme climatic events and how these are being affected by climate change. In particular, I work on producing, evaluating and applying physically-based simulations of the atmosphere and climate, with a focus on understanding extreme atmospheric weather systems. One of my partnerships is with climateprediction.net, who use distributed computing to produce very large simulation datasets containing thousands of examples of possible weather systems, facilitating the study of extremes (you can even volunteer your own computer’s time for this, if you would like). Past work of mine has included leading the scientific development of a high-resolution global atmospheric model (by the standards of typical models) to use in that system. Before joining Bristol, I did my PhD and postdoc work at the University of Oxford.

My work also includes improving our climate and weather simulators and post-processing of their output by using machine learning approaches. This is cross-disciplinary work with partners in computer science and industry.

GROUP Postdocs

Eunice Lo

I am interested in climate variability and change, and their impacts on human health. The goal of my research is to generate scientific evidence to inform climate adaptation and mitigation policies, so that fewer people will be adversely affected by climate change. Since joining the Bristol Climate Dynamics Group in 2017, I have been investigating the impacts of extreme temperatures (e.g. heatwaves) on human mortality. I have recently joined the wider university research institutes as a Research Fellow in Climate Change and Health. I am keen to expand my research to other climate exposures and form new collaborations with researchers from health sciences.

Hannah Bloomfield

I joined the University of Bristol in September 2021. My current research is focused on combined windstorm and flood risk across Europe, in a present and future climate. I spent the last eight years working at the University of Reading studying the impacts of climate variability and climate change on national-level power systems including Europe, Mexico, India, and multiple regions of Africa. A key outcome of my work has been to improve the accessibility of large meteorological datasets to non-specialists within the energy, insurance, and financial sectors. I am passionate about science communication, particularly in engaging the general public in climate science.

GROUP PhD & MScR Students

Erin Walker

My PhD investigates the uncertainties surrounding future extratropical cyclones under current climate projections, focusing on the North Atlantic Ocean and the British Isles. I use climate models to explore the changes in storm tracks, extreme precipitation and the impacts vertical resolution has on extreme event attribution. Additionally, I am interested in policy development that aims to adapt to and mitigate the impacts caused by extreme weather conditions. During my PhD, I completed a three-month placement with the Welsh Government working on coastal adaptation climate change policies. I am keen to gain more experience and develop a further understanding of the development of evidence-based policies regarding climate change and our environment.

Emily Ball

I joined the group after completing my undergraduate and masters in mathematics at Oxford. My research focuses on understanding the driving mechanisms of polar vortices in extreme climates, using Mars’ annular polar vortex as a primary example. I use the modelling framework Isca to explore the impact of changing planetary parameters and radiative forcing on polar vortices, and I am also using Martian reanalysis data to explore the variability in the vortex.

Emily Vosper

I am currently studying for a PhD which draws together ideas from the fields of Artificial Intelligence and Climate Change Science. Last year I undertook a Master’s by research project where I investigated the future impacts of hurricane rainfall on the Caribbean and found that as extreme hurricane rainfall events will be less likely if global temperatures are stabilised at 1.5°C compared to 2°C above preindustrial levels. I am currently looking at using machine learning to estimate heat-related mortality in countries with sparse data.

Henry Addison

I’m a PhD student in Interactive Artificial Intelligence at the University of Bristol. I have spent time in both academia and industry, including degrees in Mathematics and Computer Science and working for many years as a software developer. I joined the group for my PhD as I am interested in applying AI to climate science. I’m currently looking at ways of using machine learning to produce high-resolution precipitation projections more cheaply and ensuring the work benefits producers and consumers of projection datasets.

Daniel Cotterill

I joined the Climate Dynamics Group as a PhD student, whilst working at the UK Met Office as a Climate Scientist in the Climate Detection and Attribution team. My main research interests are focussed on climate change extremes, in particular extreme precipitation changes over the UK and the translation of these into Flooding Impacts. I am also interested in changes in weather patterns over the European region and their implications for different weather hazards.

Dan Green

I joined the Climate Dynamics Group at the University of Bristol in September 2021 as a MScR student, having graduated from Loughborough University with an undergraduate degree in Geography. My research project focuses on extreme heat events in Africa, seeking to quantify and provide robust evidence of recent changes to heatwaves and its drivers. Additionally, it will look to project changes to temperature extremes during the 21st century. I also have a wider interest in climate change science communication and public engagement.

Regan Mudhar

I am a PhD student at the University of Exeter, having graduated from the University of Bristol in 2019 with a MSci in Physics with Astrophysics. Will Seviour and Dann Mitchell co-supervised my masters project (with Zoë Leinhardt) on building a climate model of Titan’s atmosphere, and are now two of my current PhD supervisors. As part of the ArctiCONNECT project, I am using the modelling framework Isca to study the impacts of Arctic amplification on the stratosphere.

Mark Hammond

I joined the Climate Dynamics Group for 6 months in 2021 to study polar vortices in exoplanet atmospheres. Previously I worked at the University of Chicago, and received my PhD from the University of Oxford. I study the atmospheres of exoplanets, in particular the circulation of novel planetary archetypes such as tidally locked planets. This has included the observable features of the planet 55 Cancri e, and the mechanism by which an observable hot-spot shift forms on such planets. I am interested in developing predictive theoretical models that can be tested with real observations.

Natalie Lord

My main research interests relate to how global and regional climates respond to changes in forcings over different time scales, and the potential impacts of these changes. Most recently, my interests have focussed on how extreme heat stress events in different regions may change in the future, and the implications for society. I’m also interested in climatic changes occurring over much longer timescales in response to orbital and atmospheric carbon dioxide forcing. I was with the University of Bristol for 8 years, having also completed a PhD there.
