The early pioneer work was done at the Institute for Advanced Study in Princeton, New Jersey, together with John von Neumann. His areas of research included free and thermally driven circulations, frontogenesis, and shear and gravitational–acoustic wave propagation in stratified media. Eliassen received the Carl-Gustaf Rossby Research Medal in 1964 for his many important contributions to dynamical meteorology. He received the Balzan Prize in 1996 "For his fundamental contributions to dynamic meteorology that have influenced and stimulated progress in this science during the past fifty years".
Eliassen was a brother of architect Trond Eliassen.
