rcatool.utils.atmosphys.brunt_vaisala_frequency(ddict, model, lower_plevel, upper_plevel)[source]

Calculate Brunt-Vaisala frequency in layer bounded by two pressure levels. Pressure must be given in hPa, temperature (T) in Kelvin and specific humidity (q) in kg/kg.

Parameters:

  • ddict (dictionary) – Data dictionary

  • model (str) – model data to use

  • lower_plevel (float) – lower pressure surface

  • upper_plevel (float) – upper pressure surface

Returns:

N2 – The squared Brunt-Vaisala frequency

Return type:

array with floats
