SUMMARY:Progress in Radial Basis Function Methods: Adaptive Vortex-RBF Met
 hods for the Sphere and Other Advances - John Boyd\,   (University of Mich
 igan)

DESCRIPTION:Vortex methods\, in which flow is modelled by overlapping Lagr
 angian vortex blobs\, and radial basis function pseudospectral methods\, w
 hich have proven their worth for irregular\, adaptive grids\, are combined
  into a single algorithm to compute flows on a sphere. The strengths and l
 imitations of vortex-RBF methods for vortex-dominated flows with and witho
 ut rotation will be illustrated by case studies including finite amplitude
  Rossby waves\, vortex merger and deformation\, and roll-up and instabilit
 y. Other pertinent advances will be described as time permits.\n\n
