  1. 1. Evaluation of high-resolution satellite precipitation products with ground-based measurements over Europe

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Svea Bertolatus; [2020]
    Keywords : Precipitation; satellite product evaluation; passive microwave; estimates; Europe; ground- based gauge data; Earth and Environmental Sciences;

    Abstract : Determining water quantity of precipitation, spatially and temporally is fundamental for weather forecasting, applications in hydrology and meteorology, climate science and for agriculture and industry. Only satellite measurements from space are able to perform large-scale measurements covering both, ocean and land. READ MORE

  2. 2. Nowcasting with Dynamic Factor Model and Real-Time Vintage Data: A financial market actor's perspective

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Östlund; Marcel Attar; [2020]
    Keywords : Nowcasting; Macroeconomic Prediction; Dynamic Factor Model; DFM; Pseudo Real-Time Vintage data; U.S. GDP Growth Rate; Financial Market Actor; Mathematics and Statistics;

    Abstract : We develop and examine a dynamic factor nowcasting model (DFM) from the perspective of a financial market participant. The first point of analysis is the examination of its performance. Unlike other papers, we evaluate with daily frequency so that the performance metric reflects a continuous nowcasting signal.

  3. 3. 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. 4. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Ludvig Sjöberg; [2019]
    Keywords : Weather Research and Forecasting Model; Large Eddy Simulation; Microscale Meteorology;

    Abstract : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.

  5. 5. Attempts at using Bayesian neural networksfor uncertainty assessments of temperature forecasts

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

    Author : Joel Lundqvist; [2019]
    Keywords : Meteorology; Artificial neural networks; Bayesian neural networks; Forecast uncertainty; Physics and Astronomy;

    Abstract : This thesis describes attempts at estimating the uncertainty of the 2-metre temperature forecast error from a probabilistic point of view, utilizing Bayesian neural networks. Bayesian neural networks are a type of machine-learning algorithms used to find patterns in data and make probabilistic predictions. READ MORE
