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

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

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

    Abstract : 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. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height

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

    Author : Elin Kindlundh; [2020]
    Keywords : HARMONIE-AROME; ECMWF-IFS; WRF; verification; visibility; cloud base height; HARMONIE-AROME; ECMWF-IFS; WRF; verifikation; sikt; molnbashöjd;

    Abstract : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.

  4. 3. Analysis of simulation of lightning in a cold-based convective storm

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Linus Karlsson; [2018]
    Keywords : lightning; lightning flash; lightning discharge; cold-based convective cloud; convective cloud; microphysics; microphysical specie; cloud electrification; storm cell; convective storm cell; severe weather; Physics and Astronomy;

    Abstract : In this paper a simulation of a convective cell of a thunderstorm system observed 19th of June 2000 during the Severe Thunderstorm Electrification and Precipitation Study (STEPS) field campaign is being analysed. The storm system has been simulated with an Aerosol-Cloud model and the analysis is based on the output data. READ MORE

  5. 4. Case study of the extreme precipitation events in the south-western part of Sweden, August 2014

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

    Author : Anna Vesslén; [2015]
    Keywords : ;

    Abstract : In August 2014, parts of south-western Sweden were flooded due to intense precipitation. It caused large material damages and problems in the infrastructure. Since the sea surface temperature (SST) was higher than normal during the month, it was speculated that it was one of the reasons for the heavy precipitation. READ MORE
