Postdoc in Air-Sea-Ice interactions

Are you interested in working with air-sea-ice interactions with the support of competent and friendly colleagues in an international environment Are you looking for an employer that invests in sustainable employment and offers safe favorable working conditions We welcome you to apply for a PostDoc position at Uppsala University.

The Department of Earth Sciences is Swedens most comprehensive academic environment for research and education in geoscience. It offers a broad range of expertise that can contribute to solving important societal issues.

Earth is a dynamic and constantly changing planet. To understand how this planet works our researchers seek answers in the field through laboratory experiments and advanced models. Our research and education cover a wide range of disciplines including rocks and minerals weather and climate the evolution of life natural disasters wind power and energy environmental and water engineering and sustainable development.

Our research combines natural sciences and technology with social sciences and is often interdisciplinary. More than 300 people from over 30 countries work at the department both in Uppsala and at Campus Gotland.

Our six research divisions:

Geophysics Air Water and Landscape Science Mineralogy Petrology and Tectonics Natural Resources and Sustainable Development Palaeobiology Wind Energy

For more information see: turbulent fluxes across the air-sea-ice interface in the Marginal Ice Zone (MIZ) ie the transitional area between open water and pack ice are crucial for polar weather ecosystem and climate on both local and global scales. The presence of sea ice floes varying from centimeters to hundreds of kilometers in size creates an exceptionally heterogeneous surface characterized by varying roughness and temperature profiles. These characteristics significantly affect the momentum and heat fluxes across the air-sea-ice interface and other processes. Despite this significance our understanding of the turbulent fluxes across the interface in the MIZ remains fragmented and poorly represented in prevailing weather and climate models.

The postdoctoral project will focus on:

• implementing new turbulent parameterizations for the marginal ice zone (MIZ) into Earth system models (regional or global) and
• assessing the impact of MIZ processes on polar extreme cyclones and their broader implications for polar climate.

Requirements

• PhD degree in atmospheric or oceanic sciences or a closely related field or a foreign degree equivalent to a PhD degree in above field. The degree needs to be obtained by the time of the decision of employment. Priority will be given to applicants who have completed their degree no more than three years before the deadline for applications. Due to special circumstances the degree may have been obtained earlier. The three-year period can be extended due to circumstances such as sick leave parental leave duties in labour unions etc.
• Proven experience in numerical modelling including tools such as WRF EC-Earth and/or sea-ice models.
• Strong skills in scientific programming and computational modeling.
• Ability to conduct independent research while contributing effectively to a multidisciplinary and international research team.

Additional qualifications

Proficiency in a Linux/Unix environment together with strong expertise in Python and Bash scripting is highly desirable.

Candidates are strongly encouraged to bring their own ideas methods and perspectives to the project. Creativity enthusiasm and research acumen will be highly valued.
