  2. 1. Electromagnetic modeling using the partial element equivalent circuit method

    Author : Jonas Ekman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis presents contributions within the field of numerical simulations of electromagnetic properties using the Partial Element Equivalent Circuit (PEEC) method. Numerical simulations of electromagnetic properties are of high industrial interest. READ MORE

  4. 2. Investigating aerosol effects on stratocumulus clouds through large-eddy simulation

    Author : Ines Bulatovic; Annica Ekman; Caroline Leck; Ilona Riipinen; Daniel Grosvenor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol particles; stratocumulus; mixed-phase clouds; cloud microphysics; cloud radiative effects; Arctic; Arctic amplification; LES; aerosolpartiklar; stratusmoln; underkylda vattendroppar och iskristaller; molnmikrofysik; molnstrålningseffekter; Arktis; ”large-eddy simulation”; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Clouds have a large impact on Earth’s radiative budget by reflecting, absorbing and re-emitting radiation. They thus play a critical role in the climate system. Nevertheless, cloud radiative effects in a changing climate are highly uncertain. READ MORE

  5. 3. Transport and chemical processing of trace gases in deep convective clouds

    Author : Roman Bardakov; Annica M. L. Ekman; Mary C. Barth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas transport; atmospheric chemistry; convective cloud; box model; new particle formation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Deep convective clouds can efficiently transport trace gases from the planetary boundary layer to the upper troposphere. Once there, some gases will contribute to new particle formation and growth, eventually producing aerosols that are large enough to influence cloud properties, the radiative budget of the Earth, and climate.

  6. 4. Improving the understanding of cloud radiative heating

    Author : Erik Johansson; Abhay Devasthale; Michael Tjernström; Annica M. L. Ekman; Robert Pincus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clouds; radiative effects; upper troposphere-lower stratosphere; atmospheric circulation; remote sensing; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Clouds play an essential role in regulating Earth’s radiation budget by reflecting and absorbing energy at different spectra. As they interact with radiation, they can radiatively heat or cool the adjacent atmosphere and the surface. READ MORE

  7. 5. Arctic clouds - interactions with radiation and thermodynamic structure

    Author : Joseph Sedlar; Michael Tjernström; Annica Ekman; Johannes Verlinde; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; stratus; radiation; thermodynamic structure; cloud radiative forcing; seasonal transition; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Abstract : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. READ MORE
