hindcast

hindcast
 v.— «In his own work—which has included searches for objects ranging from containers of pollutants to crashed airliners—Fish uses a process called hindcasting. The process begins with documenting the exact location of debris found floating on the surface, and then using weather and water current information to calculate where it came from.» —“‘Pinger’ has key role in search for airliner” by Sarah Shemkus Cape Code Times (Hyannis, Massachusetts) June 6, 2009.
