Modelling
We test the models used for predicting future climate change by running
them in the past when we have a good idea of what the climatic conditions
were like. For example
GENIE and
ORMEN
Palaeoclimate data integration
We also compile large palaeoclimate datasets that can be used to test
climate models against. For example
Global Palaeofire Working Group and MOTIF
Generating and interpreting palaeoclimate data
The emphasis of our work here is the use of Sr isotopes for extracting
palaeoclimate information preserved in the sediments of semi-enclosed
seas like the Mediterranean.
QUEST and the carbon cycle
QUEST is the new NERC thematic programme
and will be led from Bristol. The development and application of new and
improved carbon cycle models and their thorough evaluation using observational
data.
Atmospheric Chemistry
A range of models (including an interactive atmosphere-biosphere model),
have been developed to investigate how the composition of the troposphere
is changing on global, regional and urban scales. Such models are essential
for future-impact and past climate studies.
Hydrology
The Hydrology Research Group
develops numerical models for a range of complex environmental flow and
transport problems. These include flood hydraulic simulation, groundwater
flow, pollutant transport and slope stability. There are strong research
links between the Science and Engineering faculties. The Water
and Environmental Management Research Centre (led by Prof. Ian Cluckie)
are also working on regional climate/weather models similar to the global
climate modelling group with a specific focus on rainfall processes at
a variety of scales derived using dynamic downscaling procedures.
Glaciology
Bristol Glaciology Centre
is involved in a number of climate modelling studies aimed
at combining expertise in various branches of Earth System Science (ESS)
modelling to provide understanding of the various interactions and feedbacks
between different components of the system. A particular aim of the group
is the assimilation of the huge quantities of high-resolution data now
available from satellites.
Atomistic modelling of trace impurities in geological formations
The research uses advanced simulation and modelling techniques to understand
the solid-state properties of materials at pressures in excess of millions
of atmospheres. The research gives insight into the incorporation of trace
elements into minerals and melts of geological and environmental importance.
Volcanology
Current research on natural hazards involves numerical models of complex
multiphase flows, such as occur in volcanic eruptions and avalanches.
There is also a strong link of this modelling research, in combination
with empirical information and estimation of uncertainties, to generate
quantitative hazard and risk assessments of natural hazards with development
of ensemble models that analyse hazards and risks in probabilistic terms.
Carbonate Processes
The modelling of carbonate diagenesis and pore systems, includes coupled
density dependent groundwater flow and reaction transport modelling.
