Dr Ruth Geen is an atmospheric dynamicist. Her research aims to increase confidence in projections of future regional climate by building simple, conceptual pictures of the large-scale circulations governing climate phenomena.

Qualifications

2016 - PhD in Atmospheric Physics, Imperial College London
2012 - MPhys (First Class Hons), University of Oxford

Biography

Dr Ruth Geen studied Physics at the University of Oxford, before moving to Imperial College London for her PhD in Atmospheric Physics, looking at the effects of water vapour on climate in an aquaplanet model. From 2016-2021 she worked as a Research Fellow in Mathematics at University of Exeter, researching questions in monsoon dynamics and Arctic influences on midlatitude climate. In 2022 she joined University 麻豆精选 as a lecturer in Atmospheric Sciences.

Teaching

Dr Ruth Geen teaches into Birmingham’s MSc in Applied Meteorology and Climatology, as well as supporting 2nd year fieldwork in Berlin.

Postgraduate supervision

Ruth Geen is interested in understanding fundamental processes governing large-scale atmospheric circulations, their representation in models, and their future changes, making use approaches such as hierarchical modelling. Particular areas of interest are dynamics of monsoon circulations and midlatitude weather.

If you are interested in joining the Meteorology and Climate group here at Birmingham as a graduate student, postdoc or if you looking for somewhere new for a research visit or sabbatical then please get in touch.

Research

Ruth uses a hierarchy of climate models and data to tackle problems in regional climate variability and change. By building up a basic understanding of climate phenomena with simpler, idealised models she aims to develop firmer foundations for our understanding of real-world climate. For example, areas she is currently exploring are:

  • Pathways by which warming of the Arctic may influence weather extremes (e.g. heatwaves, storms) in the midlatitudes

  • Sources of model bias in CMIP6 simulations of the East Asian Summer Monsoon
