  1. 1. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Benjamin Holmberg; [2022-09-01]
    Keywords : Tibetan Plateau; monsoon; westerlies; mesoscale; convection; precipitation; climate modelling; global reanalysis; regional downscaling; spatial resolution; re-initialization; spectral nudging; convective parameterization;

    Abstract : The Tibetan Plateau (TP) is one of the world’s most important water towers. Convective precipitation systems play an important role by providing freshwater for the highly densely populated downstream regions, but they can also cause hazardous floods. READ MORE

  3. 2. WRF-Chem vs machine learning approach to predict air quality in urban complex terrains: a comparative study

    University essay from Högskolan Dalarna/Mikrodataanalys

    Author : Andrey Kudryashov; [2020]
    Keywords : Machine learning; WRF-Chem; comparative study; air quality;

    Abstract : Air pollution is the main environmental health issues that affects all the regions and causes millions premature deaths every year. In order to take any preventive measures, we need the ability to predict pollution level and air quality. This task is conventionally solved using deterministic models. READ MORE

  4. 3. 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.

  5. 4. ACCURACY OF THE WEATHER RESEARCH AND FORECASTING (WRF) MODEL IN WIND RESOURCE ASSESSMENT : CASE STUDY ABOUT A POTENTIAL REPOWERING SITE

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Piia Heikkinen; [2020]
    Keywords : WRF;

    Abstract : This Master’s thesis studies how accurate the Weather Research and Forecasting (WRF) model is in wind resource assessment in the Nordic conditions. Besides, it is studied how big of an increase in energy production could be gained if a confidential wind farm would be repowered. READ MORE

  6. 5. 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.
