    Transalpine Pass Routes in the Swiss Central Alps and the Strategic Use of Topographic Resources

    Preistoria Alpina, 42 (2007): 109-118 ISSN 09-0157 © Museo Tridentino di Scienze Naturali, Trento 2007 Transalpine pass routes in the Swiss Central Alps and the strategic use of topographic resources Philippe DELLA CASA Department of Pre-/Protohistory, University of Zurich, Karl-Schmid-Str. ���������������������������4, 8006 Zurich, Switzerland E-mail: [email protected] SUMMARY - Transalpine pass routes in the Swiss Central Alps and the strategic use of topographic resources - Using examples from the San Bernardino and the St. Gotthard passes in the Swiss Central Alps, this paper discusses how the existence of transalpine high altitude pass routes can be inferred, even though there is a lack physical evidence, from specific Bronze and Iron Age settlement patterns in access valleys. Particular attention is given to the effect of topography within the territorial and economic organizational area on transalpine tracks and traffic routes. A set of recurring patterns, such as strategic position, natural and/or artificial protection, presence of “foreign” materials, can help identifying (settlement) sites with particular functions as regards traffic and trade within the systems of territorial organization. Moreover, the paper also addresses socio-dynamic issues of the problem of transalpine pass routes. RIASSUNTO - Passi transalpini nelle Alpi Centrali Svizzere e uso strategico di risorse topografiche -Usando esempi dal Passo di San Bernardino e dal Passo del San Gottardo nelle Alpi Centrali Svizzere, il presente contributo discute come l’esistenza di vie di transito transalpine d’alta quota possa essere dedotta, anche mancando evidenze fisiche, da specifici modelli insediativi dell’età del Bronzo e del Ferro presenti nelle valli di accesso.

Comment prévenir la première et établir, d’une manière durable, la seconde ? Ces questions ont hanté l’humanité entière, à la recherche de sa sécurité, depuis la nuit des temps. Ce dossier de l’Annuaire suisse de politique de développement reprend ces questions en examinant plus spécifiquement le rôle de la coopération internationale dans les dynamiques de conflit, de paix et de sécurité humaine. Le choix de ce thème s’est imposé pour diverses raisons. Depuis plus d’une décennie, les notions de paix et de sécurité « se sont invitées à la table » de la coopération internationale. La diplomatie « classique » s’occupe de plus en plus, depuis la fin de la guerre froide, de prévention et de règlement de conflits armés et de guerres.

Corresponding author: Marco Gabella, Phone +41-91-7562319, [email protected] Session: Developments in observing technologies. Abstract Radar is a unique tool to get real time overview on the current weather situation; however, high spatial resolution observations can only be achieved at short ranges, the angular resolution being an important limiting factor. How to tackle the emerging needs for high spatio-temporal resolution? Short-range, fast- scanning, X-band, mini radars can be a solution, especially for monitoring in details small basins prone to flash flood, towns and valleys. Cost, radiation and installation issues motivate the use of small antennas that can easily be installed on existing infrastructures or even on a truck. The paper presents lessons gained in various climates and with different X-band systems: low-cost, portable, single elevation, 10 kW systems delivering one precipitation map per minute as well as a sophisticated, fast 3D scanning, 75 kW Doppler, polarimetric radar on wheel aiming at the detection of both distributed (precipitation particles) and isolated scatterers (airplanes). The areas under surveillance include complex orography regions in the “wet” Western Alps and in the Be'er Sheva semi-arid region (Israel).

  • Current Development of the Remote Sensing Meteorological Network and the Fine Grid Weather Forecast Model for the Nuclear Power Plants Security in Switzerland

    Current Development of the Remote Sensing Meteorological Network and the Fine Grid Weather Forecast Model for the Nuclear Power Plants Security in Switzerland

    Current development of the remote sensing meteorological network and the fine grid weather forecast model for the nuclear power plants security in Switzerland Bertrand Calpini, Yves Alain Roulet, Dominique Ruffieux and Philippe Steiner Federal Office for Meteorology and Climatology, MeteoSwiss E-mail : [email protected]; Phone: +41 26 662 62 11 Abstract Each of the four nuclear power plants in operation in Switzerland is currently equipped with one meteorological tower (up to 110 m height) and standard ground based instruments which yield the basic data input to a gaussian-dispersion model. The latter is being used as short term weather forecast tool in case of a power plant accident. MeteoSwiss is currently in charge of upgrading this security tool. It is intended to use the advantage / peculiarity that the four nuclear power plants are all located on the Swiss Plateau at short distance each from another, and with wind fields channelled towards the NE to SW direction due to the presence of the Jura mountains on the NW and the Swiss Alps on the SE. The new security tool is based on the development of a high resolution numerical weather prediction NWP model linked to a meteorological network instrumented with ground based and remote sensing equipment. The NWP will be used to forecast the dynamics of the atmosphere in the planetary boundary layer (e.g. up to 2 km above ground level) over the Swiss plateau, using remote sensing instruments such as wind profilers, passive microwave instrument for temperature profiling, and a sodar for low altitude wind field. The measuring sites of the network will be located in order to generate the ideal database, the latter being assimilated in real time as data input for the fine grid NWP model.

    November 2020 Edition

    Volume – 27 Number – 3 September to November 2020 Edition The Bernese Alps, also called the Bernese Oberland (German for Highlands) is one of the highest mountain ranges in Europe and can be found in south-western Switzerland. When Switzerland became a country in 1848 it was decided there would be no official capital city in order to provide equal importance to every territory in the country. There are 26 cantons (territories) of Switzerland which are member states of the Swiss Confederation. The not well recognised “federal city” of Switzerland, is Bern. The country has four national language regions: German, French, Italian and Romansh. The Bernese Alps is the border between the canton of Bern, to the north and the canton of Valais, to the south. The people in both cantons speak predominantly French and German. The Eiger, although not the highest peak, is the most northerly mountain in the range and is famous for its’ north face. In this Callboard we will explore the history and development of the highest railway in Europe. The Jungfrau. Background Image: Wikipedia - The red arrow point provides an indicative position of Eigerwand railway station’s lookout windows in Eiger’s north face, at 46° 34’ 52” N, 08° 00’ 13” E, 2,865 metres. 1 OFFICE BEARERS President: Daniel Cronin Secretary: David Patrick Treasurer: Geoff Crow Membership Officer: David Patrick Electrical Engineer: Phil Green Way & Works Engineer: Ben Smith Mechanical Engineer: Geoff Crow Development Engineer: Peter Riggall Club Rooms: Old Parcels Office Auburn Railway Station Victoria Road Auburn Telephone: 0419 414 309 Friday evenings Web Address: www.mmrs.org.au Web Master: Mark Johnson Callboard Production: John Ford Meetings: Friday evenings at 7:30 pm Committee Meetings 2nd Tuesday of the month (Refer to our website for our calendar of events) All meeting dates are subject to the current Victorian Government Coronavirus restrictions.

  • Comparison of Two High Alpine CO2 Records from the Jungfraujoch Area

    Comparison of Two High Alpine CO2 Records from the Jungfraujoch Area

    16th Swiss Geoscience Meeting, Bern 2018 Comparison of two high alpine CO2 records from the Jungfraujoch area Stéphane Affolter*, Michael Schibig**,***, Tesfaye Berhanu**,*** and Markus Leuenberger **,***,* *International Foundation High Altitude Research Stations Jungfraujoch and Gornergrat, Bern, Switzerland ([email protected]) **Climate and Environmental Physics, Physics Institute, University of Bern, Switzerland ***Oeschger Centre for Climate Change Research, University of Bern, Switzerland The Sphinx observatory, part of the High Altitude Research Station located at the Jungfraujoch (Swiss Alps, 3570 m a.s.l.), has been hosting for decades several experiments of various research institutes worldwide and constitutes a key location for atmospheric measurements in Europe. Main features of the site are the remote setting and its exposure to pristine air masses with only sporadic pollution events originating from the lowlands. Since December 2014, we have an additional location available for research at the Jungfrau East Ridge (3690 m a.s.l.) around 1 km westward from the Sphinx observatory. It offers an alternative to the Sphinx location where space availability is limited. This new location is not accessible for tourists and thus well suited to compare air quality measurements to those recorded at the Sphinx observatory. A Picarro L2120-i laser based instrument has been installed in the East Ridge building which is continuously measuring the CO2 mole fraction in the atmosphere that can be compared with the Sphinx data (i) to evaluate the suitability of the new site and (ii) to investigate the potential pollution inherent to anthropogenic activities at the Jungfraujoch. The two years long comparison of CO2 records show a good agreement between both sites but exhibits annually averaged daily differences of less than 1 ppm whereas the corresponding nighttime values are within the measurement precision.
