CapeCell

public CapeCell(DataReference energyProfileRef,
                DataReference lfcRef,
                DataReference lnbRef)
         throws VisADException,
                RemoteException

Constructs from references to the massic energy profile, the Level of Free convection (LFC) and the Level of Neutral Buoyancy (LNB).

Parameters:

energyProfileRef - The massic energy profile reference.

lfcRef - The LFC reference.

lnbRef - The LNB reference.

Throws:

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.

Method Detail

compute

protected Data compute(Data[] datums)
                throws TypeException,
                       VisADException,
                       RemoteException

Computes the output Convective Available Potential Energy (CAPE) from the massic energy profile, level of free convection (LFC), and level of neutral buoyancy (LNB).

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data in the same order as during construction. datums[0] is the massic energy profile; datums[1] is the LFC pressure; and datums[2] is the LNB pressure.

Returns:

The corresponding CAPE.

Throws:

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

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

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.
