New People

Hola a todos! I’m Nicolás Duque and am a Colombian PhD-Student in the climatology group. My master’s thesis was about improving hydrological estimates in poorly gauged regions, by using satellite and reanalysis data provided by the eartH2Observe project. In the PhD-project I’ll be more focused on the water balance variability and its interaction with climate variability and looking at its sources and proportions of contribution. The idea is also to look at how some socio-economic variables in tropical south America react to decadal variability. In free time, I love playing bowling, playing football and dancing Salsa, also like cooking to share thoughts. You’ll find me in Of. 501


A century of column ozone monitoring: Uncovering the recovery

A new, long column ozone series from Oxford helps better separating chemical and dynamical influences on the ozone layer. This shows that the recovery of the ozone layer, though not seen in mid-latitude observations, is underway but masked by changes in atmospheric dynamics. This is the conclusion of a paper by Stefan Brönnimann that has been published in "Communications Earth & Envorinment".

Michèle is currently attaining her Master‘s degree in Geography at the GIUB. She is looking forward to a deep dive into all the treasures that the climatology archive has to offer.


Hitze und Trockensommer in der Schweiz

Vor 75 Jahren erlebte die Schweiz einen Hitze- und Trockensommer, der den Menschen jahrzehntelang als «die grosse Dürre» in Erinnerung geblieben ist. Am Geographischen Institut der Universität Bern, in Zusammenarbeit mit MeteoSchweiz, ETH Zürich, Universität Zürich, Agroscope und WSL, ist zum Thema eine neue Broschüre (und ein kurzer Film) entstanden. Darin zeichnen Wissenschaftlerinnen und Wissenschaftler aus verschiedenen Blickwinkeln nach, wie es 1947 zu diesem Rekordsommer kam und fragen, was wir daraus für die Zukunft lernen können: Was sind Ursachen und Folgen von Hitze- und Trockensommern in der Schweiz? Unter welchen Konsequenzen litten vor 75 Jahren Natur und Mensch, und wie wirken sich Hitze und Dürre heute aus? Wie normal wird ein Rekordsommer wie 1947 im Schweizer Klima der Zukunft?



More floods in a warmer world

Palaeoclimate studies suggest that past flood-rich periods coincided with cool periods, while climate projections suggest that flood risk may increase in a warming world. A contradiction? A new paper by the climatology group addresses this question by partitioning atmospheric drivers of floods into circulation changes and water vapour changes. Frequent floods in Europe in the mid 19th and early 20th century, as well as the flood-poor period in the mid 20th century, were driven by changes in atmospheric circulation. Conversely, the recent increase in flood frequency was driven by an increase in water vapoour, which in turn is driven by increasing temperature.



Winters are 3°C warmer than pre-industrial

Temperature reconstructions for the cold season based on freezing and thawing data from rivers and the observation of plants show the extent of warming over the past 300 years. Reconstruction show that northern mid-latitudes have warmed by three degrees. The new data also allow a better analysis of climate mechanisms. Particularly, the point to the important role of snow cover. These are the results of a study by the Climatology Group published today in “Nature Communications”.



Poster Award for Angela-Maria Burgdorf

The Swiss Global Change Day is a fixed entry in the agenda of every climate researcher in Switzerland, not the least because of the poster awards given to young researchers. This year the Commission for Atmospheric Chemistry and Physics of the Swiss Academy of Science awarded the poster "The Written Path to the Past" of Angela-Maria Burgdorf. Congratulations!



Arktische Gletscher und Jetstream

Durch die starke Erwärmung der Arktis verlieren Gletscher in Nordkanada und auf Spitzbergen jährlich ca. 44 Milliarden Tonnen Eis. Inter-annuelle Variabilität dieser Eisschmelze wurde bisher durch starke Westwindströmungen dominiert. Nun hat ein Team aus internationalen Forschenden mit Beitrag der Universität Bern in der Fachzeitschrift Nature Climate Change den zunehmenden Einfluss von meridionalen Luftströmungen festgestellt: Verliert Spitzbergen sehr viel Eis, verliert Nordkanada weniger, und umgekehrt. Dieses Phänomen wurde bisher nur in der Theorie aufgezeigt. Das Signal in den Gletschern könnte eine erste Bestandsaufnahme sein für solche Konsequenzen der globalen Erwärmung, Konsequenzen die auch das Wetter in Mitteleuropa betreffen könnten. Zur Studie:



Das Klima der Kleinen Eiszeit

Was können wir aus den Klimaschwankungen der Kleinen Eiszeit über die Klimaerwärmung lernen? Welche Auswirkungen hatten die Klimaschwankungen auf die Gesellschaft? Und wie erforschen wir überhaupt das Klima der Kleinen Eiszeit? Die Doku "Als es zwei Grad kälter wurde" des Bayrischen Rundfunks macht sich auf eine Spurensuche - unter anderem im Oeschger Zentrum und der Gruppe für Klimatologie:

New People

Jianquan Dong started in November as a Visiting PhD Student in the Climatology Group. Before coming to Bern, he did his PhD at Peking University in Beijing and focuses on extreme heat risk assessment and its mitigating approaches. Now during his visiting, he will further assess and analyze the spatial-temporal variabilities of extreme heat risk of China and Bern based on multi-sources datasets.


New Project "FAIRNESS"

This week the COST Action FAIRNESS (FAIR network of micrometeorological measurements) was officially launched. It is based on the conviction that managing weather-induced agricultural losses, water use for irrigation, new invasive species and disease vectors, plant diseases and pests, urban energy consumption and other problems requires making better use of available micrometeorological data. The Action intends to build a micrometeorological knowledge share platformwith an inventory of available and quality proven micrometeorological in-situ data , recommendations for measurement and data management in order to meet FAIR principles and examples of rural and urban FAIR data sets. The platform will link across various stakeholder groups and is carried by a transboundary network of researchers from 25 European countries, including the climatology group of the University of Bern.  


Beitrag im Regionaljournal Bern

Heinz Wanner, emeritierter Professor und Saba Baer, Masterstudentin, erzählen in einem Beitrag des Regionaljournals Bern von ihren Erfahrungen in der Klimaforschung. Angesichts des fortschreitenden Klimawandels werden auch die langjährigen Warnungen der Wissenschaft thematisiert.


An ensemble reconstruction of global monthly sea surface temperature and sea ice concentration 1000–1849

Within the framework of PALAEO-RA, Eric Samakinwa and co-authors from the climatology group of the University of Bern present monthly resolved SST and SIC fields for the period 1000–1849, which is suitable as boundary conditions for AGCM simulations. The 50-member ensemble spatially complete dataset is based on an existing coarse resolution annual mean temperature reconstruction, augmented with intra-annual and sub-grid scale variability that is physically consistent with information from models, proxies, and observations. With this new, freely available dataset, published in the Nature journal Scientific Data, science will gain new insights from AGCM simulations driven by realistic and temporally varying ensemble boundary conditions.


New Topics for Bachelor and Master Theses

The climatology group offers a number of interesting topics for Bachelor and Master theses. Have a look at the most recent list.


New colloquium program now available

Please note the new program of the Colloquium in Climatology, Climate Impact and Remote Sensing during autumn semester 2021.
