    Modifier and Type
    Field
    Description
    static final ParcelMode
    BOTTOM
    Compute a path for a lifted parcel whose initial conditions are based on the pressure, potential-temperature, and mixing-ratio of the sounding at maximum pressure.
    static final ParcelMode
    LAYER
    Compute a path for a lifted parcel whose initial conditions are based on the mean pressure, potential-temperature, and mixing-ratio of the atmospheric layer below the input pressure.
    static final ParcelMode
    POINT
    Compute a path for a lifted parcel whose initial conditions are based on the pressure and temperature of the input point and the mixing-ratio of the dew-point profile at the input pressure.
    static final ParcelMode
    PRESSURE
    Compute a path for a lifted parcel whose initial conditions are based on the temperature and dew-point of the profiles at the input pressure.

    Method
    Description
    Element
    createElement(XmlEncoder encoder)
    Returns the XML element corresponding to this instance.
    boolean

  • Field Details

    • POINT

      public static final ParcelMode POINT
      Compute a path for a lifted parcel whose initial conditions are based on the pressure and temperature of the input point and the mixing-ratio of the dew-point profile at the input pressure.

    • PRESSURE

      public static final ParcelMode PRESSURE
      Compute a path for a lifted parcel whose initial conditions are based on the temperature and dew-point of the profiles at the input pressure. This differs from POINT in that the initial temperature is taken from the temperature profile rather than the input point.

    • LAYER

      public static final ParcelMode LAYER
      Compute a path for a lifted parcel whose initial conditions are based on the mean pressure, potential-temperature, and mixing-ratio of the atmospheric layer below the input pressure.

    • BOTTOM

      public static final ParcelMode BOTTOM
      Compute a path for a lifted parcel whose initial conditions are based on the pressure, potential-temperature, and mixing-ratio of the sounding at maximum pressure. That is, the bottom of the sounding.

  • Method Details

    • createElement

      public Element createElement(XmlEncoder encoder)
      Returns the XML element corresponding to this instance.
      Specified by:
      createElement in interface XmlPersistable
      Parameters:
      encoder - The XML encoder.
      Returns:
      The corresponding XML element.

    • initFromXml

      public boolean initFromXml(XmlEncoder encoder, Element elt)

      Returns an instance corresponding to an XML element. Because this class encodes instances using the "factory" tag, this method should never be invoked.

      This implementation always returns true.

      Specified by:
      initFromXml in interface XmlPersistable
      Parameters:
      encoder - The XML encoder.
      elt - The XML element
      Returns:
      true if it is OK to do the default processing for this XML element.
