geocat.comp.skewt_params.showalter_index(pressure, temperature, dewpt)#

Calculate Showalter Index from pressure temperature and 850 hPa lcl. Showalter Index derived from Gallway 1956.

\(shox = T500 - Tp500\) where:

  • T500 is the measured temperature at 500 hPa

  • Tp500 is the temperature of the lifted parcel at 500 hPa

Parameters

  • pressure (pint.Quantity) – Atmospheric pressure level(s) of interest, in order from highest to lowest pressure

  • temperature (pint.Quantity) – Parcel temperature for corresponding pressure

  • dewpt (pint.Quantity) – Parcel dew point temperatures for corresponding pressure

Returns

shox (pint.Quantity) – Showalter index in delta degrees celsius
