  1. 1. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

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

    Författare :Johan Lundberg; [2021]
    Nyckelord :Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Sammanfattning : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters. LÄS MER

  3. 2. Planetary boundary layer height measurements in a rural environment in southern Sweden - Relation to meteorological parameters and aerosol particle concentrations

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

    Författare :Ellen Carneheim; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter... LÄS MER

  4. 3. Cloud Observations at a Coastal site – Analysis of Ceilometer Measurements from Östergarnsholm, Sweden

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

    Författare :Aron Stenlid; [2019]
    Nyckelord :Ceilometer; Stratocumulus; cloud base height; LCL; DLS; upwelling; cloud cover;

    Sammanfattning : In this study, four and a half months of ceilometer data from Östergarnsholm are used to analyze cloud related to processes in the boundary layer. Measurements are divided into two categories, which are defined by wind direction: a continental and a marine sector. LÄS MER
