Atmospheric Transport: Volcanic Ash

Volcanic Ash Modeling Volcanic ash is a hazard to aircraft because it can degrade engine performance and navigational and operational instrumentation. Operationally, the NWS runs the ARL-developed HYSPLIT model to forecast the transport and dispersion of volcanic ash in and near the U.S. Volcanic Ash Advisory Centers’ (VAAC) (Anchorage, AK, and Washington, DC) areas of responsibility.  Volcanic ash is…

HYSPLIT Volcanic Ash Model

Volcanic Ash Model Mt. Augustine volcanic eruption(Credit: Cyrus Read, U.S. Geological Survey) Volcanic ash is hazardous to aircraft because it can degrade engine performance and navigational and operational instrumentation. Meteorologists at the VAAC and the Meteorological Watch Offices use the HYSPLIT forecasts, among other sources of information, for writing Volcanic Ash Advisories and Significant Meteorological…
