earthkit.meteo.thermo.array.lcl

earthkit.meteo.thermo.array.lcl(t, td, p, method='davies')

Compute the temperature and pressure of the Lifting Condensation Level (LCL) from dewpoint.

Parameters:

• t (number or array-like) – Temperature at the start level (K)

• td (number or array-like) – Dewpoint at the start level (K)

• p (number or array-like) – Pressure at the start level (Pa) method: str

• method (str, optional) – The computation method: “davies” or “bolton”.

Returns:

• number or array-like – Temperature of the LCL (K)

• number or array-like – Pressure of the LCL (Pa)

Return type:

tuple[ArrayLike, ArrayLike]

The LCL temperature is determined by lcl_temperature() with the given method and the pressure is computed with \(t_{LCL}\) using pressure_on_dry_adiabat().
