Use of Dispersion Models to Track Eruption Clouds (Abstract Only)
This paper presents an overview of dispersion (ash-tracking models). It focuses on their usefulness, strengths and weaknesses. The models are intended to be used to predict the structure, movement and location of volcanic ash clouds, in order to provide a rapid response. Three models that are used in North America include Hysplit (Washington Volcanic Ash Alert Centre (VAAC)), Canerm (Montreal VAAC), and Puff (National Weather Service (NWS) Anchorage, U.S. Air Force Weather Agency, Alaska Volcano Observatory (AVO) and universities). The three models are similar in that they all need specification of the initial eruption column shape and size, and gridded wind fields. They differ in the way they implement their mechanisms of transport.
