Calculate Lifted Index from the pressure temperature and parcel profile.
Lifted index formula derived from [Galway1956] and referenced by [DoswellSchultz2006]:
LI = T500 - Tp500
T500 is the measured temperature at 500 hPa
Tp500 is the temperature of the lifted parcel at 500 hPa
Calculation of the lifted index is defined as the temperature difference between the
observed 500 hPa temperature and the temperature of a parcel lifted from the
surface to 500 hPa.
pressure (pint.Quantity) – Atmospheric pressure level(s) of interest, in order from highest to
temperature (pint.Quantity) – Atmospheric temperature corresponding to pressure
parcel_profile (pint.Quantity) – Temperature profile of the parcel
pint.Quantity – Lifted Index
