International Summer School on

Climate change in the Baltic Sea region

Askö Laboratory, Trosa, Sweden, 29 August – 5 September 2016

co-organized by Baltic Earth, Stockholm University Baltic Sea Centre, Leibniz Institute for Baltic Sea Research Warnemünde and University of Rostock

Thank you to the Askö staff, lecturers and of course the students for this phantastic Summer School! We intend to be be back next year...

Interview with students and lecturers about the Askö Summer School...
A short note by the Baltic Sea Centre of Stockholm University ...

The Summer School ended with smiling faces because everybody successfully passed the exam and exercises. The spirit had been phantastic during the whole week, and the students and group exercises were just amazing. We also received a short tour around the brand new research ship “Electra” which is equipped with some of the newest technologies. A short “water crisis” was handled with ease and many buckets. A week to remember!

Organizer: The Baltic Earth programme, Stockholm University Baltic Sea Centre and Leibniz Institute for Baltic Sea Research Warnemünde announce the international summer school on “Changing climate in the Baltic Sea Region”, hosted by Askö Laboratory of Stockholm University Baltic Sea Centre.

Course period: 8 days in total, 29 August – 5 September 2016
Travel from Stockholm to Askö by bus and boat on 29 August and return on 5 September

Course site: Askö Laboratory is situated 80 km south of Stockholm in the Swedish archipelago.

Academic preparation:

We plan to have very short student presentations of, for instance, your bachelor or master thesis meant as an introduction of your studies. Please prepare 1-3 slides, max 5 minutes.

To prepare for the summer school I recommend to have a look in the BACC II book (Second Assessment of Climate Change for the Baltic Sea basin). You can download the book from http://www.baltic.earth/BACC2

Please read the the following papers:

1. Can we trust climate models? ( J. C. Hargreaves and J. D. Annan)
2. The end of model democracy? (Reto Knutti)
3. Continental-scale temperature variability during the past two millennia (PAGES 2k Consortium)

and write a half-page summary of Hargreaves and Annan which I will collect during the course. In addition to the BACC II report I recommend to have a look at the latest IPCC report: Climate Change 2013 - The physical science basis at http://www.ipcc.ch/report/ar5/wg1/. For the introduction into the "Physics of Climate" I recommend the book by Peixoto and Oort (1992), American Institute of Physics.

Course Description

The course will focus on past and future changes in climate in the Baltic Sea region. The Baltic Sea is a semi-enclosed sea with a large freshwater supply from rivers of the adjacent catchment area in the transition zone between maritime and continental climates in northern Europe.  Many long-term observational data are available and provide a good knowledge about oceanic changes during the past two centuries and even longer periods. Proxy-data of the past 1,000 to 2,000 years bear witness of a pronounced climate variability in the region.

Students will be introduced to fundamental processes of the atmosphere, ocean, sea-ice and land surface with relevance for the climate system. We will start from basic principles and equations of motion that describe the circulation and dynamics in the atmosphere, ocean and sea-ice. The available knowledge in the literature about water and energy balances will be presented. Further basic methods of the analysis and modeling of the regional climate system will be introduced, including the statistical analysis of time series to identify changes in regional climate. We will explain atmospheric pressure patterns of the large-scale circulation like the North Atlantic circulation with influence on the Baltic Sea and the corresponding catchment area. The students will also be introduced to the functioning of the wind-driven and thermohaline circulations of the Baltic Sea.

Furthermore, the course will deal with coupled atmosphere-ocean climate models, climate change, the greenhouse gas effect and other drivers of regional climate, dynamical downscaling, and the variability of circulation and regional climate. We will also study the possible impact of climate change on the marine ecosystem including biogeochemical cycles. With the help of teachers from several disciplines, a holistic Earth System approach will be presented although the main focus of the course is on the physical aspects of changing climate. In addition to lectures, tutorials, exercises and literature studies the course will give the students the opportunity to discuss the learned topics further during group exercises.
