WHY IS THE ATMOSPHERE BECOMING DRIER? THE ROLES OF ATMOSPHERIC PROCESSES
AND VEGETATION FEEDBACKS, AND THEIR IMPLICATIONS FOR FUTURE CLIMATE CHANGE.

Supervisors Dr Julie Jones (University of Sheffield, UK), Dr Kate
Willett (Climate Monitoring and Attribution Group, Met Office, UK),
Prof. Colin Osborne (University of Sheffield, UK), Dr Robert Bryant
(University of Sheffield, UK)

Relative humidity (RH) over land has declined steeply since 2000. This
signal was largely unexpected and does not appear clearly in historical
reconstructions from climate models although large scale drying over
land is expected in the longer term. The drying signal is relatively
consistent from the edge of the deep tropics to the mid-latitudes of
both hemispheres, whereas regions equatorward and poleward show
increasing RH trends. Potential drivers for these signals, such as
faster warming over land than ocean, and the El Niño Southern
Oscillation have been discussed, but not systematically explored. This
atmospheric drying therefore remains poorly understood, and its
implications for future climate changes are unknown.

This project will explore the potential atmospheric and dynamical
drivers behind these trends, by quantifying feedbacks from terrestrial
vegetation, and investigate whether these key drivers are adequately
represented in climate models exploring their implications for future
climate impacts.

This project provides an exciting opportunity to undertake
interdisciplinary research in climate and ecosystem science on a key
issue in environmental change. The project will significantly improve
our understanding of the mechanisms and impacts of climate change,
aiding model development, and improving our ability to prepare good
adaptation and mitigation strategies.

The student will work with global monitoring products such as the global
gridded land surface humidity dataset HadISDH
(<www.metoffice.gov.uk/hadobs/hadisdh>) and other global monitoring
products including reanalyses (e.g. ERA Interim); the CMIP5 climate
model data archive, and earth observation datasets for terrestrial land
use, evapotranspiration and soil moisture. They will also use model
simulations based on earth observation datasets, and ecosystem studies
including those using Free-Air CO2 Enrichment (FACE).

This is an interdisciplinary PhD, involving both climate and ecosystem
science, and will therefore suit applicants with experience of, or the
capability to develop skills in, interdisciplinary work, for example
with a background in Environmental Science, Atmospheric Physics, Plant
Sciences, Biology or Geography.

This four year studentship will be fully funded at Home/EU or
international rates. Support for travel and consumables (RTSG) will also
be made available at standard rate of £2,627 per annum, with an
additional one-off allowance of £1,000 for a computer in the first year.
Students will receive an annual stipend of £17,336.

Applications should be received and complete by Tuesday 21st February 2017.
