1. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : 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. LÄS MER
2. WRF-Chem vs machine learning approach to predict air quality in urban complex terrains: a comparative study
Master-uppsats, Högskolan Dalarna/MikrodataanalysSammanfattning : 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. LÄS MER
3. Boundary Layer Studies above lake Erken using Modelling and UAV
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : 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.

4. ACCURACY OF THE WEATHER RESEARCH AND FORECASTING (WRF) MODEL IN WIND RESOURCE ASSESSMENT : CASE STUDY ABOUT A POTENTIAL REPOWERING SITE
Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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. LÄS MER
5. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : 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.
