  1. 1. Improving Short-Range Cloud Forecasts in Harmonie-Arome Through Cloud Initialization Using Mesan Cloud Data

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

    Author : Joakim Pyykkö; [2019]
    Keywords : cloud initialization; HARMONIE-AROME; MESAN; satellite product; synoptic weather station;

    Abstract : 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

  3. 2. The Ability of Regional Climate Models to Simulate Weather Conditions on Nordenskiöldbreen, Svalbard

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

    Author : Malin Andersson; Erica Erikson; [2018]
    Keywords : Regional climate models; automatic weather station; glacier; Svalbard; Regionala klimatmodeller; automatisk väderstation; glaciär; Svalbard;

    Abstract : In this project, we analyse the ability of two regional climate models to simulate meteorological conditions on Nordenskiöldbreen, a glacier in Svalbard. To do so, regional climate model output is compared with in situ measurements from an automatic weather station. READ MORE

  4. 3. 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. 4. Meteorological Conditions on Nordenskiöldbreen Glacier, Svalbard (2009 – 2015)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Niclas Bergman; [2017]
    Keywords : Svalbard; Nordenskiöldbreen; glacier; albedo; Svalbard; Nordenskiöldbreen; glaciär; albedo;

    Abstract : Glacial environments in the Arctic are a much-studied topic as well as a field of research with strong influences regarding the current and future global climate of our planet. This report is focused on the meteorological conditions on Nordenskiöldbreen glacier from 2009-2015 and how they correlate with each other, the glacier surface and the surrounding terrain. READ MORE

  6. 5. Design of renewable energy powered solar cool research centre

    University essay from KTH/Kraft- och värmeteknologi

    Author : Prageeth Rathnasooriya; [2012]
    Keywords : Solar PV; Photovoltaics; Solar Cooling;

    Abstract : Solar cooling research center is being developed on CSEM-UAE outdoor research facility in RAK/UAE.  The research center is capable to test system from 1 TR cooling capacity to 10 TR cooling capacity. The source of heat is solar radiation and heat pipe type evacuated tube solar collectors are used to collect the solar energy. READ MORE
