1. A Comparison of Statistical Methods to Generate Short-Term Probabilistic Forecasts for Wind Power Production Purposes in Iceland
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Accurate forecasts of wind speed and power production are of great value for wind power producers. In Southwest Iceland, wind power installations are being planned by various entities. READ MORE

2. A Case Study Evaluating the Performance of the NWP model HARMONIE in Simulating Convective Snowbands
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Convective snow bands forming over the Baltic Sea can result in heavy precipitation along the Swedish east coast. Forecasting these events well is of great importance to prevent road traffic injuries, increased pressure at hospitals and cancelled bus traffic. READ MORE

3. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : 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. Improving Short-Range Cloud Forecasts in Harmonie-Arome Through Cloud Initialization Using Mesan Cloud Data
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Previous studies, such as van der Veen (2012) and White et al. (2017), have demonstrated the potential of using measurement-based cloud data to improve Numerical Weather Prediction (NWP) based cloud forecasts. This can be done through cloud initialization; a process of injecting cloud data after the regular data assimilation in an NWP model. READ MORE

5. Impact of different atmospheric forcings on surface mass balance estimates in Greenland
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. READ MORE
