In atmospheric dynamics, oceanography, asteroseismology and geophysics, the Brunt–Väisälä frequency, or buoyancy frequency, is a measure of the stability of a fluid to vertical displacements such as those caused by convection. More precisely it is the frequency at which a vertically displaced parcel … See more Consider a parcel of water or gas that has density $${\displaystyle \rho _{0}}$$. This parcel is in an environment of other water or gas particles where the density of the environment is a function of height: See more The concept derives from Newton's Second Law when applied to a fluid parcel in the presence of a background stratification (in which the density changes in the vertical - i.e. … See more For a gas parcel, the density will only remain fixed as assumed in the previous derivation if the pressure, $${\displaystyle P}$$, … See more In the ocean where salinity is important, or in fresh water lakes near freezing, where density is not a linear function of temperature: See more • Buoyancy • Bénard cell See more WebAbstract.
