With apologies for potential cross-posting:

An exciting opportunity for a PhD studentship starting in October 2013
is available within the Climate Program of the British Antarctic Survey:

Investigating the spatial distribution of Föhn conditions and their
impact on surface melt over the Larsen Ice Shelf


1995 and 2002 saw the dramatic break-up and collapse of huge parts of
the Larsen Ice Shelf, Antarctica. It is widely accepted that
hydrofracturing (melt water enters crevasses and prevents their
refreezing) is the mechanism behind the break-up of the Larsen A and
Larsen B ice shelves. Adiabatic warming of the air on the lee side of
mountains, so called Föhn winds, are thought to provide the atmospheric
conditions for significant warming over the Larsen Ice Shelf thus
leading to the initial firn densification and subsequently providing the
melt water for hydrofracturing. Measurements have provided evidence that
in some cases Föhn events reach an Automatic Weather Station (AWS) over
100km from the foot of the Antarctic Peninsula mountains.

The project will use archived output from the Antarctic Mesoscale
Prediction System AMPS to spatially analyse surface parameters during
cases of Föhn events identified in AWS measurements during 2011. High
resolution model simulations with the Weather Research and Forecasting
(WRF) model will be used to compare how the representation of these
cases differs depending on model resolution. Model data and measurements
from various AWS on the Larsen Ice Shelf will be combined to study the
spatial and temporal distribution of Föhn events over the entire Larsen
Ice Shelf, their impact on surface melt conditions, and their potential
role in past and potential future ice shelf break ups in the area.

This NERC PhD Studentship is linked to the British Antarctic Survey
Climate Programme. In the Climate programme we use climate and weather
model simulations together with observations from both polar regions to
improve our understanding of how natural and human-induced factors
contribute to climate change. More information about the programme can
be found at
<http://www.antarctica.ac.uk/bas_research/our_research/current/programmes/climate/index.php>

Supervisors will be
Dr Amélie Kirchgaessner and Dr. John King at the British Antarctic
Survey, Cambridge
and at the University of Leeds:
Dr. Andrew Ross, Dr. Alan Gadian (School of Earth and Environment, and
National Centre for Atmospheric Science NCAS)

The student will be based at BAS, supervised by Dr. Amélie Kirchgaessner
and Dr. John King. The student will be registered in the School of Earth
and Environment at the University of Leeds with Dr. Andrew Ross as
University supervisor. A close link to NCAS will be provided through Dr.
Alan Gadian, who will act as co-supervisor in Leeds.

Applicants should hold or expect to gain a first or upper second-class
degree in Meteorology/ Atmospheric Sciences/ Physics, or closely related
relevant discipline. As the use of a sophisticated numerical model is an
essential part of the project, candidates should be highly numerate and
must be able to demonstrate evidence of good computing/IT skills. The
studentship will provide excellent training in the analysis of large
data sets and in numerical modelling. No fieldwork is planned for this
project.

The studentship is expected to last 3.5 years from October 2013. Stipend
for 2012/2013 was £13,590 p.a. For eligibility criteria, please go to:
<http://www.nerc.ac.uk/funding/available/postgrad/eligibility.asp>

Requests for further information on this studentship should be addressed
to Dr. Amélie Kirchgaessner (<acrki@bas.ac.uk>). Applications should
include a cover letter, CV and the e-mail addresses of two referees, and
should be sent to <basstudentoffice@bas.ac.uk>. Please quote reference
number BASDTG/kirc/3

Closing date for applications is 31st January 2013.
