Adrian Edmund Gill FRS (22 February 1937 - 19 April 1986) was an Australian meteorologist and oceanographer best known for his textbook Atmosphere-Ocean Dynamics . Gill was born in Melbourne Australia and worked at Cambridge, serving as Senior Research Fellow from 1963 to 1984 .
He was chair of the Tropical Ocean-Global Atmosphere programme. He was elected a Fellow of the Royal Society of London in 1986.  His candidacy citation read: "Dr A.E. Gill is internationally recognised for his work in geophysical fluid dynamics and leads a small but highly productive team working on problems in dynamical oceanography and meteorology. He has made outstanding theoretical contributions to a wide range of topics, including the stability of pipe flow, thermal convection, circulation of the Southern Ocean, seasonal variability of the ocean, waves in rotating fluids, wind-induced upwelling, coastal currents and sea-level changes and coastally-trapped waves in the atmosphere, and he is particularly effective in the way he is able to interpret observations and guide the activities of observational workers".
