What I do
Scientific research interests and projects
My interests lie in
understanding the processes responsible
for changes in climate and sea level, as observed and as
projected by atmosphere-ocean general circulation models (AOGCMs).
- Climate sensitivity and its relationship to ocean heat uptake and the Earth
energy budget: their dependence on climate and forcing, the determination and
influence of the patterns of surface temperature and other regional climate
change, the usefulness and limitations of the forcing--feedback framework. I am
the PI of the Couplet project, funded by an advanced grant from the ERC, on
transient climate change in the coupled atmosphere --ocean system.
- Sea-level change: processes of change in AOGCMs, causes of its simulated
regional distribution, comparison of simulated change and variability with tide
gauges and altimetry. I am coordinating a subproject (FAFMIP) of the current phase (CMIP6) of the
Coupled Model Intercomparison Project, with the aim of investigating the
reasons for different AOGCM projections of sea-level change, ocean heat uptake
and circulation change.
- Ocean heat uptake: how it comes about in AOGCMs, why their results differ,
how it relates to the Atlantic meridional overturning circulation, what we can
deduce from observations of change in the ocean interior. I am the PI of a
project (UKFAFMIP) funded by a NERC standard grant concerned with the
magnitude, patterns and mechanisms of sea level change and heat uptake in
response to atmospheric forcing. Matt Couldrey is working on this project. I am
a co-investigator in a project (TICTOC) funded by a NERC large grant on the
investigation of ocean temperature and circulation change in observations and
models using passive tracers. Quran Wu is working on this project.
- Changes in ice sheets and their contribution to sea-level
change. I am involved in the development of the ice-sheet/shelf modelling
component of the UK Earth system model, and in the ice-sheet subproject
(ISMIP6) of the current phase of the Coupled Model Intercomparison Project.
I am a co-investigator in a project led by Robin Smith
funded by a NERC standard grant on modelling past changes in the ice-sheets
in order to constrain projections of the future
using FAMOUS and UKESM coupled to the BISICLES ice-sheet model.
I am a member of the steering committee
for the ISMIP6
subproject of CMIP6.
- Development of the FAMOUS Earth
system model. Robin Smith is the manager of FAMOUS.
