lifted_condensation_level =========================== .. py:function:: lifted_condensation_level(t, td, p) Computes the Lifted Condensation Level (LCL) for a parcel ascending from a given temperature, dewpoint and pressure. :param t: initial temperature (K) :type t: number, ndarray or :class:`Fieldset` :param td: initial dew point temperature (K) :type td: number, ndarray or :class:`Fieldset` :param p: initial pressure (Pa) :type p: number, ndarray or :class:`Fieldset` :rtype: dict or None The LCL is the level where the parcel becomes saturated during an adiabatic ascend. First, the LCL temperature is computed with the formula from [Bolton1980]_: .. math:: t_{LCL} = 56.0 + \frac{1}{\frac{1}{td - 56} + \frac{log(\frac{t}{td})}{800}} Then the LCL pressure is computed from :math:`t_{LCL}` using the dry adiabatic equations. The result is a dict with two members: "t" and "p", containing the temperature and pressure of the LCL, in K and Pa units, respectively. On error or if the LCL does not exist None is returned. .. mv-minigallery:: lifted_condensation_level
