WebIn atmospheric dynamics and oceanography, the Brunt-Väisälä frequency, or buoyancy frequency, is the frequency at which a vertically displaced parcel will oscillate within a statically stable environment. In the atmosphere, , where θ is potential temperature, g is the local acceleration of gravity, and z is geometric height. Web(December 2009) In atmospheric dynamics, oceanography, and geophysics, the Brunt–Väisälä frequency, or buoyancyfrequency, is the angular frequency at which a vertically displaced parcel will oscillate within a statically stable environment. It is named after David Bruntand Vilho Väisälä. Contents 1Derivation for a general fluid

Webwhere σ is the root-mean-square turbulent velocity in the convective region near the interface, N 2 is the Brunt-Väisälä frequency, L is a typical length scale for turbulent motions, and the convective interface is assumed to span some radial extent ranging from r 1 to r 2. There is degeneracy in how r 1, r 2, and L are defined in the ... Webbuoyancy frequency). If N 2 is negative, then N itself is imaginary, and solutions to (19) are z t Ae Be() N t N t . (21 ) These solutions are exponential with time, and are not oscillatory. The Brunt-Väisälä frequency frequency is directly related to the static stability of the atmosphere.

WebA derivation of the Brunt-Väisälä frequency, valid in regions of a star where both partial ionization and a varying nuclear composition are present, is given. The final result shows that even in regions where the total ionization approximation is valid, a reduction of the Brunt-Väisälä when compared to the Ledoux criterion is necessary. Areas where this …
