  2. 1. Variability and feedbacks in the middle atmosphere

    Author : Maartje Kuilman; Bodil Karlsson; Qiong Zhang; Hauke Schmidt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Middle atmosphere dynamics; noctilucent clouds; solar cycle effects; climate feedbacks; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The importance of the middle atmosphere for the weather and climate on Earth is increasingly realized. Variability and feedback processes in the middle atmosphere need to be better understood and form the subject of this thesis. READ MORE

  4. 2. Uncertainties in tropical precipitation and radiative feedbacks under climate change

    Author : Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

  5. 3. Improving satellite measurements of clouds and precipitation using machine learning

    Author : Simon Pfreundschuh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precipitation; clouds; remote sensing; machine learning;

    Abstract : Observing and measuring clouds and precipitation is essential for climate science, meteorology, and an increasing range of societal and economic activities. This importance is due to the role of clouds and precipitation in the hydrological cycle and the weather and climate of the Earth. READ MORE

  6. 4. The use of a satellite-derived cloud climatology for studying cloud-aerosol processes and the performance of regional cloud climate simulations

    Author : Karl-Göran Karlsson; Erland Källen; Jon-Egil Kristjansson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clouds and climate; satellite cloud climatology; validation of clouds; clouds and aerosols; Meteorology; Meteorologi;

    Abstract : The entry of satellite-derived decadal cloud datasets with homogeneous coverage in time and space enables studies not possible before. This thesis presents two such applications. The first study deals with cloud-aerosol processes and the second with an evaluation of cloud simulations from a regional climate model. READ MORE

  7. 5. Aerosol-Cloud-Precipitation Interactions - Studied using combinations of remote sensing and in-situ data

    Author : Moa Sporre; Ergonomi och aerosolteknologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clouds; aerosol particles; climate; precipitation; satellite data; Fysicumarkivet A:2016:Sporre;

    Abstract : Cloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. READ MORE
