  1. 1. Climate Change and Precipitation Variability Influence on the Greenland Ice Sheet

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

    Author : Jennie Olsson; [2018]
    Keywords : Physics; Ice Sheet; Surface Mass Balance; SMB; Representative Concentration Pathways; RCP; Climate Change; Greenland; Precipitation; Precipitation Variability; Glaciers; Glacier; Meteorology; Greenhouse Effect; Greenhouse Gas; Future Climate; Climate; Physics and Astronomy;

    Abstract : Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. READ MORE


    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : FRANK ARTHUR; [2018]
    Keywords : Carbon dioxide fluxes; Gas transfer Velocity; Turbulence; Eddy covariance; Stream flow; Wind speed; Global Carbon cycle; Latent and sensible heat fluxes.;

    Abstract : River, lakes and   streams account for more carbon dioxide emissions than all other freshwater   reservoirs together. However, there is still lack of knowledge of the   physical processes that control the efficiency of the air-water exchange of   CO2 in these aquatic systems. READ MORE

  3. 3. 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

  4. 4. Using machine learning to identify the occurrence of changing air masses

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Anund Bergfors; [2018]
    Keywords : machine learning; meteorology; data science; visualization; time series; pattern recognition; logistic regression; data mining; statistics; ai; physics; signal processing; control theory; automatic control; systems theory; information technology; maskininlärning; meteorologi; data science; visualisering; tidsserie; mönsterigenkänning; logistisk regression; datautvinning; statistik; ai; fysik; signalbehandling; reglerteknik; systemteknik; informationsteknologi;

    Abstract : In the forecast data post-processing at the Swedish Meteorological and Hydrological Institute (SMHI) a regular Kalman filter is used to debias the two meter air temperature forecast of the physical models by controlling towards air temperature observations. The Kalman filter however diverges when encountering greater nonlinearities in shifting weather patterns, and can only be manually reset when a new air mass has stabilized itself within its operating region.

  5. 5. Linguistic uncertainty in meteorological forecastsfor Russian speaking audiences : A comparative study between televised weather forecastsand seasonal outlooks of the Northern Eurasian ClimateOutlook Forum

    University essay from Högskolan Dalarna/Ryska

    Author : Freja S. E. Vamborg; [2018]
    Keywords : Russian; linguistics; linguistic markers; uncertainty; communication; communication guidelines; climate; meteorology; weather forecasts; seasonal forecasts;

    Abstract : In order to make informed decisions, we need to resort to various types of information and we need to know how uncertain this information is. A commonly used source for information and subsequent action is weather forecasts. READ MORE
