  2. 1. Artificial intelligence in weather and climate prediction : Learning atmospheric dynamics

    Author : Sebastian Scher; Gabriele Messori; Roberto Buizza; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Weather and climate prediction is dominated by high dimensionality, interactions on many different spatial and temporal scales and chaotic dynamics. This makes many problems in the field quite complex ones, and also state-of-the-art numerical models are - despite their immense computational costs - not sufficient for many applications. READ MORE

  4. 2. Beyond Köhler theory : Molecular dynamics simulations as a tool for atmospheric science

    Author : Thomas Hede; Caroline Leck; Veli-Matti Kerminen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Köhler theory; molecular dynamics; surface tension; aggregate; climate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : In this thesis, the results from molecular dynamics (MD) simulations of nanoaerosol clusters are discussed. The connecting link of these studies is the Köhler theory, which is the theory of condensational growth and activation of cloud droplets to form clouds. READ MORE

  5. 3. Simulations of Coastal Atmospheric Dynamics and Transport Processes

    Author : Ragothaman Sundararajan; Dimitris Melas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; coastal atmosphere; dynamics; transport; Lagrangian particle dispersion model; mesoscale model; turbulence; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Abstract : The marine atmosphere can be highly variable in space and time, and the coastal terrain plays a crucial role in influencing its properties. These, in turn, determine the atmospheric transport in the coastal zone. READ MORE

  6. 4. Noctilucent clouds in a coupled atmosphere

    Author : Bodil Karlsson; Peter Sigray; Jacek Stegman; Scott Bailey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Noctilucent clouds; atmospheric dynamics; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Abstract : Noctilucent clouds (NLC) at altitudes around 80 km are the highest clouds in our atmosphere. They have been a subject of research ever since their discovery in the late 19th century. This thesis takes an important step towards using NLC as a tool for studying dynamic coupling processes in the atmosphere on a global scale. READ MORE

  7. 5. Multi-satellite views on mesospheric microphysics and dynamics

    Author : Lina Broman; Jörg Gumbel; Susanne Benze; Scott Bailey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polar mesospheric clouds; satellite tomography; remote sensing; cloud microphysics; wave dynamics; mesosphere; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Atmospheric gravity waves of different scales and origins strongly modulate the wind field and temperature structure of the higher parts of the atmosphere. Direct and continuous measurements of these processes are particularly complicated in the mesosphere at about 50 to 100 km height due to the remote location of this region. READ MORE
