  1. 1. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Ludvig Sjöberg; [2019]
    Nyckelord :Weather Research and Forecasting Model; Large Eddy Simulation; Microscale Meteorology;

    Sammanfattning : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.

  2. 2. Meteorologiska mätningar med drönare

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

    Författare :Christopher Greenland; [2019]
    Nyckelord :Drones; UAV; wind speed; wind direction; carbon dioxide; temperature; relative humidity; quadcopter; vertical profile; Drönare; UAV; vindhastighet; vindriktning; koldioxid; temperatur; relativ fuktighet; quadcopter; vertikal profil;

    Sammanfattning : Studien handlade om att belysa hur UAV:s kan komma till nytta i meteorologisk forskning och att ta reda på hur bra drönare är på att mäta meteorologiska storheter. Drönare, som också kallas UAV:s (Unmanned Aerial Vehicle) är mindre obemmanade luftfartyg som kan flyga autonomt eller fjärrstyras. LÄS MER

  3. 3. Climate Change and Precipitation Variability Influence on the Greenland Ice Sheet

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Jennie Olsson; [2018]
    Nyckelord :Physics; Ice Sheet; Surface Mass Balance; SMB; Representative Concentration Pathways; RCP; Climate Change; Greenland; Precipitation; Precipitation Variability; Glaciers; Glacier; Meteorology; Greenhouse Effect; Greenhouse Gas; Future Climate; Climate; Physics and Astronomy;

    Sammanfattning : Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. LÄS MER

  4. 4. CARBONDIOXIDE FLUXES FROM A CONTROLLED BOREAL RIVER

    Master-uppsats, Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Författare :FRANK ARTHUR; [2018]
    Nyckelord :Carbon dioxide fluxes; Gas transfer Velocity; Turbulence; Eddy covariance; Stream flow; Wind speed; Global Carbon cycle; Latent and sensible heat fluxes.;

    Sammanfattning : River, lakes and   streams account for more carbon dioxide emissions than all other freshwater   reservoirs together. However, there is still lack of knowledge of the   physical processes that control the efficiency of the air-water exchange of   CO2 in these aquatic systems. LÄS MER

  5. 5. Skyfall som orsak till extrem jorderosion

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jonas Bredelius; [2018]
    Nyckelord :;

    Sammanfattning : Heavy rain may cause significant erosion and damage to natural and anthropogenic landforms. The purpose of this paper is to describe the most extensive events of soil erosion from heavy rain that are recorded in Sweden and how the prerequisites of this weather phenomena is affected by different future climate scenarios.
