The contour-advective semi-Lagrangian hybrid algorithm approach to weather forecasting and freely propagating inertia-gravity waves in the shallow-water system
(University of St Andrews, 2009-06-24) - ThesisThis thesis is aimed at extending the spherical barotropic contour-advective semi-Lagrangian (CASL) Algorithm, written in 1996 by David Dritschel and Maarten Ambaum, to more complex test cases within the shallow-water ... -
Balance, gravity waves and jets in turbulent shallow water flows
(University of St Andrews, 2009) - ThesisThis thesis contains a thorough investigation of the properties of freely decaying turbulence in a rotating shallow water layer on a sphere. A large number of simulations, covering an extensive range of Froude and Rossby ... -
Equilibrium and dynamics of collisionless current sheets
(University of St Andrews, 2009-06-24) - ThesisIn this thesis examples of translationally invariant one-dimensional (1D) Vlasov-Maxwell (VM) equilibria are investigated. The 1D VM equilibrium equations are equivalent to the motion of a pseudoparticle in a conservative ... -
Magnetic skeletons and 3D magnetic reconnection
(University of St Andrews, 2008-06-23) - ThesisThe upper atmosphere of the sun, the solar corona, is approximately 1,000,000K hotter than the surface of the Sun, a property which cannot be explained by the normal processes of heat conduction and radiation. It is now ... -
Solar flux emergence : a three-dimensional numerical study
(University of St Andrews, 2008-06) - ThesisFlux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales ...
