  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. The influence of clouds on Earth's radiation budget in global climate models

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Johannes Karlsson; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Considering the high sensitivity of climate to changes in cloudiness, the way clouds might change in a perturbed climate is important for the total temperature response. In fact, the cloud feedback has been identified as the main uncertainty in future projections, as simulated by global climate models. READ MORE

  3. 3. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets

    Abstract : Geomorphological evidence of glaciations exist for the Last Glacial Maximum (about 20 kyr ago). At this time, both North America and Eurasia were covered by extensive ice sheets which are both absent today. READ MORE

  4. 4. Chemical characteristics of atmospheric aerosols : the influence of natural and man-made sources and sinks

    University dissertation from Stockholm : Department of Meteorology , Stockholm Unviersity

    Author : Michael Norman; Stockholms universitet.; Stockholms universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; meteorologi; Meteorology;

    Abstract : In order to improve the understanding of the climatic and environmental effects of atmospheric aerosol particles, knowledge about their sources, sinks, chemical and physical characteristics as well as transportation in the atmosphere is needed. This thesis examines the water-soluble chemical characteristics of aerosol particles and precipitation and their interaction with trace gases. READ MORE
