  1. 1. A Statistical Overview of the Spatial Atmospheric Variability Over Isfjorden, Svalbard

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Stenlund Agnes; [2022]
    Nyckelord :meteorologi; atmosfärsvetenskap; mikroklimat;

    Sammanfattning : The atmospheric spatial variability over Isfjorden, Svalbard, was investigated through statistical data analysis. The data used in the thesis was measured by mobile weather stations installed on three ships crossing the fjord, and two stationary weather stations close to the shoreline, during the autumn of 2021 and spring to autumn 2022.

  3. 2. Characterization of Wind Channeling Around Longyearbyen, Svalbard

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Michael Lonardi; [2018]
    Nyckelord :Longyeardalen; wind channeling; snow transport;

    Sammanfattning : Due to climate change and arctic amplification, the avalanche activity is expected to increase at higher latitudes (Hall et al., 1994). The arctic settlement of Longyearbyen, Svalbard, situated inside the valley Longyeardalen, is yearly threatened by avalanche activity (Eckerstorfer & Christiansen, 2011a). LÄS MER

  4. 3. An Analysis of the Local Weather Around Longyearbyen and an Instrumental Comparison

    Uppsats för yrkesexamina på grundnivå, Institutionen för geovetenskaper

    Författare :Charlotta Petersson; [2007]
    Nyckelord :meteorology; Svalbard; the Arctic; Longyearbyen; local weather; channeling effects; sea breeze; inversion; case study; instrumental comparison;

    Sammanfattning : Three different studies have been made; an analysis of the general weather situation at three weather stations in Svalbard, close to the main settlement Longyearbyen; an instrumental comparison between three weather stations operating at nearly the same place during a few days in October 2006; and a case study of a weather station at the mountain Breinosa compared to the station in the valley beneath. The analysis of the general weather at the three stations, Adventdalen (data used from 2004-2006), Svalbard Airport (data used from 1994-2004) and Gruvefjellet (data used from 2002-2005) showed that it is clear that the local surroundings do contribute to a more locally produced weather.

  5. 4. Case studies of the bora wind. Numerical simulations in three dimensions

    Kandidat-uppsats, Uppsala universitet/Meteorologiska institutionen

    Författare :Anna Sjöblom; [1996]
    Nyckelord :;

    Sammanfattning : Two days with bora has been numerically analysed, using a three dimensional hydrostatic mesoscale model developed at the Department of Meteorology, Uppsala University. The two simulated days, 22 March and 15 April 1982, have been compared to aircraft measurements done during the ALPEX-SOP in 1982. LÄS MER
