dry_lapse

metpy.calc.dry_lapse(pressure, temperature, ref_pressure=None)[source]

Calculate the temperature at a level assuming only dry processes.

This function lifts a parcel starting at temperature, conserving potential temperature. The starting pressure can be given by ref_pressure.

Parameters
  • pressure (pint.Quantity) – The atmospheric pressure level(s) of interest

  • temperature (pint.Quantity) – The starting temperature

  • ref_pressure (pint.Quantity, optional) – The reference pressure. If not given, it defaults to the first element of the pressure array.

Returns

pint.Quantity – The resulting parcel temperature at levels given by pressure
