public final class SaturationPointTemperature
extends AirTemperature

Provides support for the quantity of saturation-point temperature. Saturation-point temperature is the temperature at which a parcel of air lifted dry-adiabatically will become saturated.

An instance of this class is immutable.

create

public static Data create(Data pressure,
                          Data temperature,
                          Data mixingRatio)
                   throws TypeException,
                          VisADException,
                          RemoteException

Creates a saturation-point temperature data object from data objects for pressure, temperature, and water-vapor mixing-ratio. The empirical formula is taken from "An Introduction to Boundary Layer Meteorology" by Roland B. Stull; chapter 13 (Boundary Layer Clouds).

Parameters:

pressure - The air pressure data object.

temperature - The temperature data object.

mixingRatio - The water-vapor mixing-ratio data object.

Returns:

The saturation-point temperature data object corresponding to the input arguments.

Throws:

TypeException - An input argument has wrong type.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.
