A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

1992 Spurr Eruption Case Discussion
27 Apr 2011 | Contributor(s):: William I Rose
This lecture summarizes distal ash cloud observations via satellite and radar, along with information about meteorology and fallout, for the 1992 Crater Peak/Spurr eruptions. These small subplinian events produced significant fine and very fine ash fallouts that were sampled and measured. Even...
Weather Radar Systems (Lacasse et al)
This lecture describes the vital observations that can be made by ground-based weather radar systems. It is based on a paper written by Lacasse et al and which is attached in the supporting documents of this presentation.Lacasse, C, S Karlsdóttir, G Larsen, H Soosalu, W I Rose and G G J...
