Constructor Detail

LclPressureCell

public LclPressureCell(visad.DataReference initPresRef,
                       visad.DataReference initTempRef,
                       visad.DataReference lclTempRef)
                throws visad.VisADException,
                       java.rmi.RemoteException

Constructs from data references.

Parameters:

initPresRef - The input initial pressure reference.

initTempRef - The input initial temperature reference.

lclTempRef - The input LCL temperature reference.

Throws:

visad.VisADException - if a VisAD failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.

Method Detail

compute

protected visad.Data compute(visad.Data[] datums)
                      throws visad.TypeException,
                             visad.VisADException,
                             java.rmi.RemoteException

Computes the output condensation pressure (the pressure at the LCL) from the parcel's initial pressure and temperature, and the temperature at the Lifting Condensation Level (LCL).

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data in the same order as during construction. datums[0] is the initial pressure; datums[1] is the initial temperature; and datums[2] is the temperature at the LCL.

Returns:

The corresponding condensation pressure.

Throws:

java.lang.ClassCastException - if an input data reference has the wrong type of data object.

visad.TypeException - if a VisAD data object has the wrong type.

visad.VisADException - if a VisAD failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.
