bruntVaisallaOmegaSquared {aiRthermo}

Brunt-Vaisalla (angular) frequency (squared)

Description

Brunt-Vaisalla (angular) frequency (aquared, s^{-2}) considering hydrostatic equilibrium. P is used as a vertical level.

Usage

bruntVaisallaOmegaSquared(Ps, Ts, ws, consts = export_constants())

Arguments

Ps

A vector with pressure values (Pa).

Ts

A vector with temperature values (K).

ws

A vector with mixing ratio values (kg/kg).

consts

The constants defined in aiRthermoConstants data are necessary. The constants g and Rd are used.

Details

The angular frequency (squared, s^{-2}) is returned in order to avoid complex numbers.

Value

The Brunt-Vaisalla (angular) frequency (squared) is returned.

Note

For stable atmospheres, should be positive at every level. Ps, Ts and ws are 1D arrays.
