Surface based parcel - temperature and dewpoint of the bottom layer of the sounding.
Mixed layer parcel - average potential temperature and average mixing ratio of the lowest 100 hPa.
Most unstable parcel - parcel with highest cape when starting in the lowest 300 hPa.
Convective temperature - lowest temperature required for surface based convection.
Virtual temperature correction - CAPE & CIN computed with virtual temperature, can be switched ON/OFF under settings.
Storm relative helicity - measure of the potential for cyclonic updraft rotation, computed with .
