static_stability

metpy.calc.static_stability(pressure, temperature, vertical_dim=0)[source]

Calculate the static stability within a vertical profile.

\[\sigma = -\frac{RT}{p} \frac{\partial \ln \theta}{\partial p}\]

This formula is based on equation 4.3.6 in [Bluestein1992].

Parameters

  • pressure (pint.Quantity) – Profile of atmospheric pressure

  • temperature (pint.Quantity) – Profile of temperature

  • vertical_dim (int, optional) – The axis corresponding to vertical in the pressure and temperature arrays, defaults to 0.

Returns

pint.Quantity – The profile of static stability

Changed in version 1.0: Renamed axis parameter vertical_dim
