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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Petros Stergiou; [2023]
    Keywords : 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;

    Abstract : 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). READ MORE

  3. 2. Large-Scale Atmospheric Drivers of Extreme Temperature Anomalies During Springtime in the Arctic

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Linnea Barreng; [2022]
    Keywords : Meteorology; Temperature extremes; Arctic; Jet stream; Rossby waves; Spring; Meteorologi; Arktis; Extremväder; Jetström; Rossbyvågor; Vår;

    Abstract : In this project warm extreme temperature events in the Arctic region during the spring months March, April and May were identified and analysed. In the analysis daily average NCEP reanalysis data from NOAA/OAR/ESRL PSL format was used. READ MORE

  4. 3. Inter-annual memory effects between soil moisture and NDVI in the Sahel

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Yang Zhou; [2013]
    Keywords : Physical Geography and Ecosystem Science; GEM; memory effect; soil moisture; Sahel; rainfall; land cover; soil type; remote sensing; Earth and Environmental Sciences;

    Abstract : The Sahel lies in the semi-arid zone of North Africa between the Sahara Desert to the north and the savannas and rainforest to the south. In the Sahel, the variability of vegetation growth is predominately controlled by moisture reception in the concurrent rainy season. READ MORE

  5. 4. Study and implementation of mesoscale weather forecasting models in the wind industry

    University essay from KTH/Kraft- och värmeteknologi

    Author : Bénédicte Jourdier; [2012]
    Keywords : Mesoscale; weather; wind; energy; WRF;

    Abstract : As the wind industry is developing, it is asking for more reliable short-term wind forecasts to better manage the wind farms’ operations and electricity production. Developing new wind farms also requires correct assessments of the long-term wind potentials to decide whether to install a wind farm at a specific location. READ MORE

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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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.
