Joseph Tribbia and Philip Thompson begin with an introduction and Thompson provides a brief history of numerical weather prediction and how he knew Arnt Eliassen. Thompson then starts by asking Eliassen about his interest in numerical prediction, Jule Charney and Vilhelm Bjerknes. Eliassen responds and comments on the people who influenced him in the field and their scientific works. Eliassen then discusses his initial exposure to meteorology at the University of Oslo and how his interest developed. From there, Eliassen talks about his occupation as a weather forecaster during WWII and then comments on his quasi-geostrophic system equations.
