Measured in number of students and teachers, the Faculty of Science at the University of Helsinki is the largest science faculty in Finland. There are some 6,000 students taking a basic degree. Out of them, some 1,000 are postgraduates. There are some 500 international students, and over 200 researchers and teachers from abroad.

Institute for Atmospheric and Earth System Research (INAR) is a multi- and interdisciplinary research unit based in physics, chemistry, meteorology, forest sciences, environmental sciences and social sciences in the University of Helsinki. INAR aims to strengthen the internationally leading, integrated multidisciplinary research and education environment for atmospheric and Earth system science and to feed in scientific results for the national and international environment and climate policy. It performs multiscale research from molecular to global scale and focuses on climate change, air quality, biogeochemical cycles and ecosystem processes. INAR has INAR Finland Network partners in Finnish Meteorological Institute, University of Eastern Finland and Tampere University of Technology.

Faculty of Science invites applications for

DOCTORAL STUDENT IN EXTRA-TROPICAL CYCLONE DYNAMICS AND A POSTDOCTORAL RESEARCHER IN MACHINE LEARNING APPLIED TO METEOROLOGY

starting in September 2021 for fixed-term contracts of four years (doctoral student) or 2 years 4 months (postdoc) in the Academy of Finland funded research project “Quantifying controls on the intensity, variability and impacts of extreme European STORMS”

The aim of the STORMS project is to determine what environmental factors (e.g. mean temperature) govern the maximum intensity, structure and variability of extra-tropical cyclones and how the intensity and impacts of these weather systems are likely to change in the future. The project will utilize a unique combination of idealised modelling simulations performed with the numerical model OpenIFS, ERA5 reanalysis, and machine learning techniques. In collaboration with the University of Oxford (UK), a public distributed computing network (https://www.climateprediction.net/) will be exploited to perform a massive ensemble of simulations.

The postdoctoral researcher will be responsible for designing and running the ensemble of OpenIFS simulations and for developing post-processing code or adding diagnostics to the OpenIFS source code to calculate the required metrics of extra-tropical cyclone intensity. The postdoctoral researcher will use machine learning methods to identify which parameters have the strongest control on the intensity of extra-tropical cyclones and will create and evaluate statistical emulators for different measures of extra-tropical cyclone intensity.

The doctoral student will develop methods to quantify the dynamical intensity of extra-tropical cyclones and the potential societal impact of extra-tropical cyclones. Once these diagnostics are established, the doctoral student will identify controls on extra-tropical cyclone intensity, structure, and the precursors to cyclone development, in different regions of the North Atlantic storm track using ERA5 reanalysis data. The doctoral student will also quantify how applicable the results obtained from the idealised OpenIFS simulations are to the real atmosphere by applying the statistical emulators developed by the postdoctoral researcher.

The candidate for the doctoral student position must apply for a position in the Doctoral Programme for Atmospheric Sciences (ATM-DP) during the fall 2021 application round. The appointee’s main duties consist of postgraduate studies and writing a doctoral dissertation related to the project’s topic. Teaching can take up to 5% of annual working time of 1612 hours.

The applicants for doctoral student position should
- hold a Master’s degree (or be about to hold) in a field that is relevant to the research topic such as meteorology or atmospheric sciences;
- have an excellent understanding of atmospheric dynamics;
- demonstrate a strong interest in studying extra-tropical cyclones using reanalysis data and numerical modelling;
- have knowledge of a programming language such as Python, Matlab or Fortran;
- have some experience of using UNIX/Linux operating systems;
- have good skills in written and spoken English.

The applicants for postdoctoral researcher position should
- hold a Doctoral degree in a field that is relevant to the research topic such as atmospheric sciences, meteorology, climate science, data science, computing science or physics;
- have excellent skills in UNIX/Linux operating systems, high performance computing, and managing large data sets;
- have considerable experience in advanced statistics and machine learning methods, and ideally, experience in the development and use of statistical emulators.
- have demonstrable experience of programming languages such as Python, Matlab, Fortran or Metview;
- have experience of compiling and running numerical weather prediction models;
- have good skills in written and spoken English;
- have a willingness to work internationally and spend a considerable amount of time at the University of Oxford (UK) working with our collaborators.
