    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Vir Sjöberg; [2023]
    Nyckelord :Late Neolithic; Early Bronze Age; Gotland; re-analysis; paleopathology microarchaeology; unmarked grave; communal burial; Senneolitikum; äldre bronsålder; Gotland; återanalys; paleopatologi mikroarkeologi; flatmarksgrav; gemensam grav;

    Sammanfattning : This thesis presents a micro-archaeological analysis of the osteological material from theunmarked communal grave L1977:6727, in Sigsarve, Gotland. The grave was found during the ploughing of a field and excavated in 1911. LÄS MER

  3. 2. Co-occurring Cold Extremes in North America and Unusually Warm Weather in Europe

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

    Författare :Petros Stergiou; [2023]
    Nyckelord :Extreme temperature events co-occurrence; cold spells; warm extremes; Europe; North America; Pan-Atlantic atmospheric teleconnections; Samtidiga extrema temperaturhändelser; kalla extrema; varma extrema; Europa; Nordamerika; Pan-Atlantiska atmosfäriska telekopplingar;

    Sammanfattning : In this project, we identified and examined the 50 coldest extreme temperature eventsin North America (CENA) and the 50 warmest extreme temperature events insouthwestern Europe (WEEU) during the winter seasons from 1948 to 2023. For theanalysis, we utilized daily NCEP-NCAR reanalysis data for temperature, sea levelpressure (SLP), and 500hPa geopotential height (Z500). LÄS MER

  4. 3. Investigation of Emission Source Heights in FLEXPART 10.02 for the Wildfire in Pedrógão Grande, Portugal, 2017

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

    Författare :Anton Nygren; [2019]
    Nyckelord :wildfire; Pedrógão Grande; structural similarity; SSIM; FLEXPART; MERRA2; CO; emission source height; skogsbränder; Pedrógão Grande; strukturell likhet; SSIM; FLEXPART; MERRA2; CO; utsläppshöjd;

    Sammanfattning : One of the worst wildfires in Portugal in 2017 on June17- 21 started at the central part of Pedrógão Grande and spread fast to the surrounding areas Góis, Pampilhosa da Serra and Arganil. The wildfire took 64 lives and a large smoke plume was observed. LÄS MER

  5. 4. Temporal Consistency of the UERRA Regional Reanalysis: Investigating the Forecast Skill

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

    Författare :Adam von Kraemer; [2018]
    Nyckelord :Temporal consistency; reanalysis; forecast skill; UERRA; HARMONIE; Tidsmässig konsistens; återanalys; prognoskvalitet; UERRA; HARMONIE;

    Sammanfattning : Weather forecasting has improved greatly since the middle of the 20th century, thanks to better forecasting models, an evolved weather observing system, and improved ways of assimilating the observation data. However, these large systematical improvements make it difficult to use the weather data for climatological studies. LÄS MER

  7. 5. Regional Precipitation Study in Central America, Using the WRF Model

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

    Författare :Tito Maldonado; [2012]
    Nyckelord :WRF; Central America; precipitation; dynamical downscaling; regional models; reanalysis; cumulus parameterization schemes.; WRF; Centralamerika; nederbörd; dynamiska nedskalning; regionala modeller; reanalys; cumulus parametrisering system;

    Sammanfattning : Using the regional climate model WRF, and the NCEP-NCAR Reanalysis Project data asboundary and initial conditions, regional precipitation was estimated by means of thedynamical downscaling technique for two selected periods, January 2000 and September2007. These months show very particular climatic characteristics of the precipitationregimen in Central America, like dry (wet) conditions in the Pacific (Caribbean) coast of theCentral American isthmus, in January, and wet (dry) conditions, respectively in each coast,during September.
