geocat.comp.meteorology.showalter_index(pressure, temperature, dewpt)

Deprecated since version 2022.12.0: showalter_index is deprecated. Use metpy.calc.showalter_index instead. See the MetPy documentation.

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

\(shox = T500 - Tp500\)

• T500 is the measured temperature at 500 hPa

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

Parameters

• pressure (pint.Quantity, array-like, int, float) – Atmospheric pressure level(s) of interest, in order from highest to lowest pressure in hectoPascals

• temperature (pint.Quantity, array-like, int, float) – Parcel temperature for corresponding pressure in degrees Celcius

• dewpt (pint.Quantity, array-like, int, float) – Parcel dew point temperatures for corresponding pressure in degrees Celcius

Returns

shox (same type as input) – Showalter index in delta degrees Celsius

Note

pressure, temperature, and dewpt must all be pint.Quantity objects or all plain, unitless numbers.
