Borehole and ground surface temperatures and their relationship to meteorological conditions in the Swiss Alps


Hoelzle, M; Gruber, S (2008). Borehole and ground surface temperatures and their relationship to meteorological conditions in the Swiss Alps. In: 9th International Conference on Permafrost, Fairbanks, Alaska, 29 June 2008 - 3 July 2008, 723-728.

Abstract

In Switzerland, several boreholes are monitored within the framework of the Permafrost Monitoring Switzerland (PERMOS). Three of these boreholes, at Murtèl, at Schilthorn, and at Stockhorn, are at least 60 m deep. In addition, a number of shorter boreholes (c. 6 m deep) were drilled in other projects and have been continuously observed over several years. Results on long- and short-term behavior of these boreholes are presented and compared to standard meteorological components, such as air temperatures and snow cover, measured directly at these borehole sites or nearby. First analyses show the importance of the snow cover duration and thickness; more important on a local scale are different surface and subsurface characteristics influencing heat transfer by conduction and heat capacity. The concept of different offsets between atmosphere and lithosphere is discussed, and data reflecting these offsets are presented for typical alpine conditions.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
