Kieran Brophy Dr. Heather Graven/ Prof. Juliet Pickering Atmospheric studies of CO2 emissions from fossil fuel combustion  
Kelvin Choi Dr. Helen Brindley  Building a Long-term Record of the Global Solar Energy Resource from Satellite Observations  The aim of this PhD is to further develop the radiative transfer capability within the RAL algorithm such that the quantities most pertinent for assessing the solar resource and informing solar cell design are routinely generated. Once implemented and evaluated, the dataset will be fed into solar cell simulation tools in order to estimate the electricity generation potential for different cell designs as a function of location. In this way the optimal cell technology and/or design for different regions can be identified based on real, long-term observations.

Entropy Production in the Earth System

Everything which occurs - from rain to wind to the act of reading this sentence - must be part of a process which increases entropy, producing 'disorder' which can't be restored. The sun provides the renewing high-quality energy for the Earth system, while the long-wave radiation leaving the planet carries away the low-quality, high-entropy energy so that the planet can exist in a steady pseudo-equilibrium. My project studies the quantity of entropy flux in and out of the system, characterising and summarising the net effect of the processes which occur in the climate. We hope that this will provide a new, simple lens with which to view the climate, climate change, and our attempts to model it.

Joanna Lester Dr. Heather Graven/ Dr. Arnaud Czaja (Imperial) and Samar Khatiwala (Oxford) Studying ocean circulation, acidification and CO2 uptake using models and tracers  

The ocean is currently taking up around 25% of anthropogenic CO2 emissions. However, the uptake of CO2 by the ocean is strongly determined by ocean circulation, which is sensitive to climate change and subject to complex feedbacks. I am using observations of oceanic transient tracers collected on ship-based cruises, including radiocarbon and chlorofluorocarbons, to compare with ocean models to investigate ocean transport and mixing processes, how these processes respond to climate change, and the resulting impacts on the oceanic uptake of anthropogenic CO2 and ocean acidification.

 

Yi Li Prof. Ralf Toumi Regional ocean data assimilation and forecast  

Data assimilation is an approach to fuse observation and numerical models to produce optimal state estimation. In my project, I'm using ensemble data assimilation algorithm to improve the forecast of ocean currents. I'm also working on the forecast of tropical cyclones by assimilating ocean observations.

I am interested in examining seasonality of human mortality, both sub- and multi-nationally, and how climate change may be influencing the patterns and trends evident. 

My research includes building mathematical models both to analyze past trends of seasonality of human mortality and to forecast possible futures for climate change risk assessment.

Peter Shatwell Dr. Arnaud Czaja, David Ferreira (Uni of Reading), Greg Pavliotis (Imperial Maths) A process study of heat uptake by the global ocean A compilation of hydrographic surveys over the 20th century and the recent development of the ARGO float program have revealed significant variability in oceanic heat content in all basins. Some of these changes must be related to the heat-content increase in response to the accumulation of CO2 and other long-lived greenhouse gases in the atmosphere, but some must also reflect fluctuations intrinsic to the coupled ocean-atmosphere-cryosphere system. Due to limited observations and the costly computing requirements to study deep ocean heat uptake, our understanding of these fluctuations is poor.
The goal of this PhD project is to step back and conduct a process study of heat content change, or heat uptake, by different elements of the global ocean circulation: wind driven gyres (the global ocean), buoyancy-forced overturning circulation in a narrow basin (North Atlantic), and wind- and buoyancy-forced circulation in a channel geometry (Southern Ocean). The aim is to develop simple (linear and, possibly, stochastic) models of heat uptake i.e. models in which knowledge of the pre-industrial oceanic state allows for a prediction of heat uptake in response to anthropogenic forcing. This prediction will then be applied and compared to observations.

Applications of AI to Catastrophic Weather Event Prediction

 

My work aims to use image recognition algorithms on satellite images to match realtime data to prior and simulated datasets to better constrain the characteristics and movements of tropical cyclones. This work therefore looks to provide faster more accurate forcasts than current weather predictions as these cyclones unfold.
