metpy.calc.most_unstable_cape_cin(pressure, temperature, dewpoint, **kwargs)[source]

Calculate most unstable CAPE/CIN.

Calculate the convective available potential energy (CAPE) and convective inhibition (CIN) of a given upper air profile and most unstable parcel path. CIN is integrated between the surface and LFC, CAPE is integrated between the LFC and EL (or top of sounding). Intersection points of the measured temperature profile and parcel profile are linearly interpolated.

  • pressure (pint.Quantity) – Pressure profile
  • temperature (pint.Quantity) – Temperature profile
  • dewpoint (pint.Quantity) – Dewpoint profile

  • pint.Quantity – Most unstable Convective Available Potential Energy (CAPE).
  • pint.Quantity – Most unstable Convective INhibition (CIN).
