  1. 1. Boundary Layer Studies above lake Erken using Modelling and UAV

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

    Författare :Oliver Nordvall; [2020]
    Nyckelord :Internal Boundary Layer; UAV; Sea Breeze Circulation; Numerical Simulation; WRF; lake Erken; Internt gränsskikt; UAV; Sjöbris; Numerisk simulation; WRF; Erken;

    Sammanfattning : Internal boundary layers (IBLs) above lakes, created primarily by the autumn differential of land and lake surface temperatures, present a unique way of studying the lake-atmosphere coupling within the boundary layer. The small and mobile unmanned aerial vehicles (UAVs) contribute to new research areas within the boundary layer, offering high spatial resolution measurements to complement already existing observations.

  3. 2. An Investigation of the Relation between Sea Breeze Circulation and Diurnal Variation of Methane at a Swedish Lake

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

    Författare :Martin Svensson; [2015]
    Nyckelord :WRF model; Sea breeze; methane emission; diurnal variation; internal boundary layer; WRF-modellen; sjöbris; metanemission; dygnsvariation; internt gränsskikt;

    Sammanfattning : Methane measurements over lake Tämnaren show a pronounced diurnal variation with high values at night and low values during daytime. The atmosphere over the lake and its surroundings is simulated with two different settings and resolutions of the WRF model during a period of eight days in May 2011 to investigate if a lake/land breeze circulation could be the cause of the observed methane variation.

  4. 3. Evaluation of a New Lateral Boundary Condition in the MIUU Meso-Scale Model

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

    Författare :Anna Jansson; [2002]
    Nyckelord :mesoscale model; MIUU mode; boundary condition;

    Sammanfattning : The MIUU meso-scale model has been used to evaluate a new lateral boundary condition. The new lateral boundary condition is a combination of two lateral boundary conditions used in regional models, the flow relaxation scheme and the tendency modification scheme. LÄS MER

  5. 4. The wind field in coastal areas

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

    Författare :Niklas Sondell; [2001]
    Nyckelord :coastal meteorology; internal boundary layer; effect of surface properties; wind field; stability effects;

    Sammanfattning : The land-sea transition in coastal areas makes the meteorological conditions rather complex and the structure of the coastal boundary layer is important for many reasons. Two examples are air pollution dispersion and wind energy potential. The wind field off the coast when offshore flow is present has been studied. LÄS MER

  7. 5. Effects of a Sea Breeze Circulation on Fluxes in the Marine Boundary Layer Over the Baltic Sea

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ingrid Eronn; [2000]
    Nyckelord :;

    Sammanfattning : Two days in May 1997 has been studied. During one of the days a sea breeze circulation occured, and the two days were compared in search for effects from the sea breeze on the fluxes in the marine boundary layer. LÄS MER
