CASE PhD studentship in the Climate Processes Group at the University of Oxford and the UK MetOffice
Disentangling aerosol effects on shallow convection from meteorological co-variability
Clouds play a key role in the earth system. Shallow convection is by far the most frequent global cloud regime yet its representation in global weather and climate models remains incomplete. It is crucial to improve their representation in global weather and climate models to correctly represent the response to anthropogenic perturbations.
While aerosol effects on shallow convection have been suggested from theory, modelling and observations, they remain highly uncertain. Not even the sign of the response to increased levels of cloud condensation nuclei is clear: both an increase in cloud abundance due to reduction in precipitation efficiency as well as a decrease in cloud abundance due to enhancement of evaporation associated with smaller droplets have been reported.
This project has the objective to disentangle aerosol effects on shallow convection from the meteorological co-variability inherent in observational studies. It builds on novel capabilities of the high-resolution set-up of the UK MetOffice Unified Model with the Cloud AeroSol Interacting Microphysics (CASIM) cloud microphysics and UKCA aerosol microphysics .
This studentship is a joint CASE studentship with supervisors Prof. Philip Stier (Climate Processes Group in the Department of Physics at the University of Oxford) and Prof. Paul Field (UK MetOffice) in cooperation with the Max Planck Institute for Meteorology (Germany). It benefits from the combination of academic and professional supervision and the experience and world leading expertise of the MetOffice in the development and evaluation of cloud representations in numerical models as well as from access to the excellent facilities provided by the MetOffice . In addition, it is anticipated that the student will spend a research sojourn at the Max Planck Institute for Meteorology.
This CASE studentship supported by the MetOffice provides an annual supplement to the standard NERC studentship as well as additional support for research expenses. It will be affiliated with the Physical Climate Stream of the Oxford Doctoral Training Partnership in Environmental Research (http://www.environmental-research.ox.ac.uk/researchstream/the-physical-climate-system/), providing an outstanding training environment in a year-group of 30 students.
Please direct informal inquiries to Prof. Philip Stier (firstname.lastname@example.org).
Applications can be made online with an application deadline of 29 April 2016. Interviews will be held on 16 May.
