  1. 6. Analysis and comparison of weather models for solar irradiance forecasts in Sweden

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

    Author : Linus Falk; [2018]
    Keywords : meteorology; weather models; ensemble forecasts; solar irradiance; Physics and Astronomy;

    Abstract : Solar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. READ MORE

  3. 7. Temporal Consistency of the UERRA Regional Reanalysis: Investigating the Forecast Skill

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Adam von Kraemer; [2018]
    Keywords : Temporal consistency; reanalysis; forecast skill; UERRA; HARMONIE; Tidsmässig konsistens; återanalys; prognoskvalitet; UERRA; HARMONIE;

    Abstract : Weather forecasting has improved greatly since the middle of the 20th century, thanks to better forecasting models, an evolved weather observing system, and improved ways of assimilating the observation data. However, these large systematical improvements make it difficult to use the weather data for climatological studies. READ MORE

  4. 8. The Vertical Route Forecast : an Evaluation of a New Flight Path Based Weather Forecast Product with HARMONIE-AROME High Resolution Forecasts over Scandinavia

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Ingela Leffler; [2017]
    Keywords : Vertical route forecast; Model evaluation; HARMONIE-AROME; GFS; Aviation weather; Vertikal ruttprognos; Modellutvärdering; HARMONIE-AROME; GFS; Flygväder;

    Abstract : As a complement to existing weather forecast products for aviation, a prototype of a new product is presented and evaluated. It shows the atmosphere in a vertical cross section along the intended route. READ MORE

  5. 9. Analyzing Meteorological Relationships to Aerosols in China

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

    Author : Carl Svenhag; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Meteorological conditions are influenced everyday by air-bound aerosols and pollution in the atmosphere, and understanding these processes from micro to synoptic scale, is essential for forecasting and creating high resolution weather models. In this study, three different experimental weather models are analysed to provide some understanding on how various meteorological parameters are influenced by modelling atmospheric aerosols.

  6. 10. Sensitivity studies on difficult cloud and fog situations for weather model

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

    Author : Axel Stigborg; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Fog and clouds are difficult to predict for meteorologist today. Models have a tendency to show either too much or too little clouds or fog, which can be a problem for people and industries that depend on the weather conditions. Improvements are being done, but errors still occur. READ MORE
