  1. 1. Turbulence Intensity During Low-Level Jets in the Baltic Sea

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

    Author : Thomasson August; [2021]
    Keywords : Low-Level Jet; Turbulence intensity; Shear sheltering; LiDAR; Baltic Sea; Low-Level Jet; Turbulensintesitet; Shear sheltering; LiDAR; Östersjön;

    Abstract : Low-level jets (LLJs) are local wind speed maximums in the atmospheric boundary layer. In the Baltic Sea, LLJs are frequently occurring in spring and summer. It is an important phenomena to consider for wind energy parks, and changes in turbulence during the jets can effect the efficiency of said parks. READ MORE

  3. 2. Verification of the local similarity theory above forests

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

    Author : Yasmin Hubmann; [2021]
    Keywords : Forest Meteorology; Boundary Layer Meteorology; Wind Energy; Local Similarity Theory; Monin–Obukhov Similarity Theory; Flux-Gradient Formulation; Richardson Number Formulation; Turbulence Statistic; Rotor Equivalent Wind Speed; Grenzschicht-Meteorologie; Forstmeteorologie; Windenergie; Lokale Ähnlichkeitstheorie; Monin–Obukhov’sche Ähnlichkeitstheorie; Fluss-Gradient-Ähnlichkeit; Gradient-Richardson-Zahl Beziehung; Turbulenzcharakteristiken; Rotor-äquivalente Windgeschwindigkeit; Skogsmeteorologi; Gränsskiktsmeteorologi; Vindenergi; Lokal Similaritetsteori; Monin–Obukhov Similaritetsteori; Flöd-Gradient Relation; Richardson Gradienttal Relation;

    Abstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.

  4. 3. Modeling wind-induced currents in lake Bolmen, Sweden, using TELEMAC 2D

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Prasanjaya Bandara Ekanayake; [2021]
    Keywords : Bolmen Lake; TELEMAC 2D; Wind induced currents; QGIS; Blue Kenue; Technology and Engineering;

    Abstract : Transport and material intermixing within lake systems have a significant impact on lake water quality. However, since researchers are primarily concerned with biological, environmental, and ecological aspects, physics and hydrodynamic behavior in lake water currents frequently receive less attention.

  5. 4. The Eemian Baltic Sea hydrography and paleoenvironment based on foraminiferal geochemistry

    University essay from Lunds universitet/Geologiska institutionen

    Author : Julia Chonewicz; [2020]
    Keywords : trace elements; benthic foraminifera; last interglacial; temperature reconstruction; geochemistry; Earth and Environmental Sciences;

    Abstract : I den här masteruppsatsen undersöktes geokemin i kalkskalen av bottenlevande foraminiferer från Anholt (Kattegat), Ristinge (Bälthavet) och Obrzynowo (Egentliga Östersjön), för att rekonstruera de hydrografiska förhållanden i Östersjön och paleomiljön under den senaste interglacialen (130 - 115 ka BP). De variabler som analyserades innefattade Mg/Ca, Ba/Ca och Mn/Ca samt stabila syre- och kolisotoper (δ18O och δ13C) i kombination med data från tidigare studier och modern hydrografi. READ MORE

  6. 5. An annual evaluation of CH4 oxidation in a freshwater lake

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Eldina Cehic; [2020]
    Keywords : Methane oxidation; isotopic fractionation; stratification; open steady-state and closed system.; Metanoxidation; isotopfraktionering; stratifiering; öppet stabilt system och stängt system;

    Abstract : Freshwater lakes constrain its methane (CH4) emissions through CH4 oxidation. CH4 includes three carbon (C) isotopes; the stable isotopes 12C,13C and the unstable and more uncommon isotope 14C. Methanotrophs (i.e. READ MORE
