  1. 1. Optical Turbulence Characterization for Ground-Based Astronomy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Susanna Hagelin; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; site testing; atmospheric effects; turbulence; optical turbulence; applied meteorology; mesoscale models; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik; Meteorologi; Meteorology;

    Abstract : The optical turbulence, which creates perturbations of the wavefronts coming from the stars, is caused by small-scale fluctuations in the index of refraction of the atmosphere and is a problem for astronomers because it limits the maximum resolution of the ground-based telescopes. One way of identifying the best sites to build astronomical observatories, where the influence of the optical turbulence is as small as possible, is to use the standard meteorological parameters to get a first idea of the potential of a site.

  2. 2. On the representation of precipitation in high-resolution regional climate models

    University dissertation from Stockholm : Department of Meteorology

    Author : Petter Lind; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Regional climate modeling; high-resolution; convection parameterization; precipitation; extremes; statistical analysis; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi; meteorologi; Meteorology;

    Abstract : Weather and climate models applied with sufficiently fine mesh grids to enable a large part of atmospheric deep convection to be explicitly resolved have shown a significantly improved representation of local, short-duration and intense precipitation events compared to coarser scale models. In this thesis, two studies are presented aimed at exploring the dependence of horizontal resolution and of parameterization of convection on the simulation of precipitation. READ MORE

  3. 3. Radiative transfer in the absorption bands of oxygen : Studies of their significance in ozone chemistry and potential for aerosol remote sensing

    University dissertation from Stockholm : Stockholm University

    Author : Gijs Koppers; Stockholms universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; meteorologi; Meteorology;

    Abstract : Among the scientific topics of greatest public interest are the ozone question and climatic change. The discovery of the Antarctic ozone hole in 1985 and recognition of large scale ozone depletions in the northern hemisphere focused the world's attention on human induced changes in the atmosphere.

  4. 4. Wind Turbine Sound in Cold Climates

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristina Conrady; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric acoustics; wind turbine sound; outdoor sound propagation; cold climates; Meteorologi; Meteorology;

    Abstract : The increase in the number of wind turbines (WTs) in populated areas in cold climates increases the number of people potentially being affected by WT sound. Outdoor sound propagation is strongly dependent on meteorological conditions, however, limitations in the knowledge exist regarding the implications of meteorological conditions in cold climates.

  5. 5. Turbulence modelling applied to the atmospheric boundary layer

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Werner Lazeroms; KTH.; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulence; RANS models; explicit algebraic Reynolds-stress models; buoyancy; stable stratification; thermal convection; atmospheric boundary layer;

    Abstract : Turbulent flows affected by buoyancy lie at the basis of many applications, both within engineering and the atmospheric sciences. A prominent example of such an application is the atmospheric boundary layer, the lowest layer of the atmosphere, in which many physical processes are heavily influenced by both stably stratified and convective turbulent transport.
