1. Precipitation Nowcasting using Deep Neural Networks
Master-uppsats, KTH/FysikSammanfattning : Deep neural networks (DNNs) based on satellite and radar data have shown promising results for precipitation nowcasting, beating physical models and optical flow for time horizons up to 8 hours. “MetNet”, developed by Google AI, is a 225 million parameter DNN combining three different types of architectures that was trained on satellite and radar data over the United States.

2. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. LÄS MER
3. A Case Study Evaluating the Performance of the NWP model HARMONIE in Simulating Convective Snowbands
Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : 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. LÄS MER
4. Flow simulation in MIKE URBAN based on high-resolution X-band radar data
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Radar har använts sedan 1940-talet för att mäta och övervaka nederbörd. Under de senaste åren har X-bandradarn visat sig vara ett verktyg som kan förbättra indata till avrinningsmodellering inom urbana avrinningsområden. Detta tack vare sin höga upplösning i tid och rum jämfört med andra radarer som används vid nederbördsmätning. LÄS MER
5. Interpretation of meteorological data in a GIS-based simulation environment
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktionSammanfattning : The main object of this thesis was to investigate the possibility of integrating a visualization of meteorological data in an interactive GIS-based simulation environment. The work was carried out at at the Swedish Defence Research Agency (FOI). Focus was put on meteorological parameters affecting radar signals. LÄS MER
