geostrofisen
Geostrofisen is a theoretical concept in geophysical fluid dynamics that describes a systematic deviation from strict geostrophic balance in rotating fluids, such as Earth's oceans and atmosphere. The term combines geostrophic balance with a suffix used in some languages to name phenomena, signaling a distinct but related effect.
In commonly used models, geostrofisen arises when friction, boundary effects, or rapid spatial changes in topography
Geostrofisen is discussed mainly in idealized theoretical frameworks and in interpretations of observations where deviations from
Mathematically, the concept is treated by incorporating frictional terms, boundary-forcing, or nonlinear and beta-plane effects into
