He also lends his name to a class of long, non-dispersive oceanic waves which flow parallel to a physical boundary in geostrophic balance.
This man lends his name to an equation, which, for a given temperature, relates supersaturation to droplet radius, in order to determine if that radius is increasing or decreasing. He also lends his name to a class of long, non-dispersive oceanic waves which flow parallel to a physical boundary in geostrophic balance. Atmospheric waves, which break due to increasing wind shear across a density interface, are named for Helmholtz and this man. Along with Joule, he is the namesake of an isenthalpic process, which sees temperature change in a real gas as pressure decreases. For 10 points, name this physicist, whose best-known contribution is his namesake absolute temperature scale.
