PhD Fellow in Physics – Climate Dynamics

The Arctic University of Norway, Tromsø, Norway
Closing date: 31 August 2022

The position is available for commencement from autumn 2022, and the appointment is for a period of four years. The nominal length of the PhD programme is three years; the fourth year is used for teaching or other duties for the department where the fellow is hired. The duties are normally distributed evenly over the four years. The objective of the position is to complete research training to the level of a doctoral degree. Admission to a PhD programme is a prerequisite for employment, and the programme period starts on commencement of the position.

The candidate will work in a team having large international cooperation and will have possibilities for a research stay abroad. The position will be supervised by the Department of Physics and Technology and possibly by international project collaborators. The workplace is at UiT in Tromsø.

The position’s field of research

The current anthropogenic emissions of greenhouse gasses lead to global warming. The Arctic is warming faster than the Earth as a whole, which is known as the Arctic Amplification. This amplification affects not only the Arctic weather and climate, but also plays a role for the mid-latitudes. The amplification may enhance mid-latitude extreme weather events so that for instance heat waves become more severe, and cold spells become more frequent.

The weather is strongly coupled to the atmospheric circulation. The atmospheric circulation transports heat and water vapour hereby affecting local temperatures and precipitation. The circulation dependents on the temperature gradient between the Equator and the pole. Hence as the global warming becomes amplified in the Arctic, the equator-to-pole temperature gradient changes and so does the atmospheric circulation and the weather in the mid-latitudes.

This PhD project is dedicated on investigating the role of the Arctic warming in changing the Northern Hemisphere mid-latitudes weather – in particular, extreme weather events. This linkage will be investigated based on a combination of climate-model experiments, and statistical analyses of observations and model output from large model ensembles. The project will contribute with important knowledge on expected future changes of extreme weather events.

The successful candidate will obtain a solid scientist education, advanced knowledge within physics, statistics, meteorology and climate science, and strong skills in programming, written and oral communication, and international cooperation.
