Numerical simulation of explosive volcanism and its effects on the atmosphere

PDF Version Also Available for Download.

Description

This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective of this project was to begin work on combining two modeling approaches in order to advance the state-of-the-art in simulating and predicting explosive volcanic eruption dynamics and their effects. The authors began applying the CFDLIB family of codes for the near field (high temperature, velocity, and particle concentration) region of an explosive eruption. The authors also applied the RAMS meteorological code to model the far-field dynamics of eruption clouds and ash fallout. Initial test runs were ... continued below

The authors also applied the RAMS meteorological code to model the far-field dynamics of eruption clouds and ash fallout. Initial test runs were conducted in preparation for full-scale simulations that would eventually couple the two models for the most comprehensive volcano simulation tool to date. Eventual applications include aviation hazards, risk assessment, and extension to atmospheric collateral effects of conventional and nuclear weapons.
