Over the past twelve years, the speaker and collaborators have developed a new method for simulating circulations in geophysical fluids. A body of water or an atmosphere is represented as a collection of conforming fluid parcels whose motions are predicted using Newtonian mechanics. The method employs a unique convective parameterization, referred to as Lagrangian Overturning (LO), in which overlapping fluid parcels exchange vertical positions in convectively unstable regions. This talk will introduce the Lagrangian method, present idealized tests that illustrate its advantages, and summarize lake, ocean and atmosphere applications completed to date, which include simulations of large lake upwelling, Atlantic meridional overturning, and tropical convective systems.
