    • Atmospheric transport and critical layer mixing in the troposphere and stratosphere 

      Smy, Louise Ann (University of St Andrews, 2012-06-22) - Thesis
      This thesis aims to improve the understanding of transport and critical layer mixing in the troposphere and stratosphere. A dynamical approach is taken based on potential vorticity which has long been recognised as the ...

    • The investigation of quasi-separatrix layers in solar magnetic fields 

      Restante, Anna Lisa (University of St Andrews, 2011-06-20) - Thesis
      The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and ...

    • The period ratio P₁/2P₂ in coronal waves 

      Macnamara, Cicely K. (University of St Andrews, 2011-11-30) - Thesis
      Increasing observational evidence of wave modes brings us to a closer understanding of the solar corona. Coronal seismology allows us to combine wave observations and theory to determine otherwise unknown parameters. The ...

    • Small-scale magnetic feature evolution as observed by Hinode/NFI and SOHO/MDI 

      Thornton, L. M. (University of St Andrews, 2011-11-30) - Thesis
      The surface (photosphere) of the Sun is threaded throughout by magnetic fields. Groups of magnetic fields form magnetic features (of a wide range of sizes in flux and area) on the surface where the fields are directed into ...

    • Current sheets in the solar corona : formation, fragmentation and heating 

      Bowness, Ruth (University of St Andrews, 2011-11-30) - Thesis
      In this thesis we investigate current sheets in the solar corona. The well known 1D model for the tearing mode instability is presented, before progressing to 2D where we introduce a non-uniform resistivity. The effect ...
