Compute the temperature on a moist adiabat (pseudoadiabat).

Parameters:

  • ept (number or array-like) – Equivalent potential temperature defining the moist adiabat (K)

  • p (number or array-like) – Pressure on the moist adiabat (Pa)

  • ept_method (str, optional) – Specifies the computation method that was used to compute ept. The possible values are: “ifs”, “bolton35”, “bolton39”. (See ept_from_dewpoint() for details.)

  • t_method (str, optional) –

    Specifies the iteration method along the moist adiabat to find the temperature for the given p pressure. The possible values are as follows:

    • ”bisect”: a bisection method is used as defined in [Stipanuk1973]

    • ”newton”: Newtons’s method is used as defined by Eq (2.6) in [DaviesJones2008]. For extremely hot and humid conditions (ept > 800 K) depending on ept_method the computation might not be carried out and nan will be returned.

Returns:

Temperature on the moist adiabat (K). For values where the computation cannot be carried out nan is returned.

Return type:

number or array-like

Implementations

temperature_on_moist_adiabat() calls one of the following implementations depending on the type of the input arguments:

The function returns an object of the same type as the input arguments.
