The Eady model refers to a theoretical framework used in meteorology to describe the behavior of atmospheric flows, particularly in the context of large-scale geophysical fluid dynamics. Named after Sir John Eady, who developed the model in the mid-20th century, it provides a simplistic representation of baroclinic instability in a two-layer system of the atmosphere.
