  This program reads the input file "sounding", which can be created using
the program "readsound.f", and calculates the temperatures and virtual
temperatures of parcels lifted reversibly and also pseudo-adiabatically
from each level (but without ice processes). It also calculates the
temperatures and virtual temperatures of parcels that are first saturated by
a wet bulb process and then descend pseudo-adiabatically to the surface;
this is done for each level in the sounding. The Convective Available
Potential Energy (CAPE), Positive Area (PA) and Negative Area (NA) are
calculated for parcel ascent from each level, for both reversible and
pseudo-adiabatic processes, and the Downdraft Convective Available
Potential Energy (DCAPE) is calculated for the downdraft process described
above. 

Output is directed to the output file "calcsound.out" and to an NCAR graphics
file. The output file "calcsound.out" contains the values of CAPE, PA, NA
and DCAPE, while the NCAR graphics file contains two contour plots showing,
the difference between the virtual temperatures (C) of reversibly and
pseudo-adiabatically lifted parcels, respectively, as a function of the
pressure level to which the parcel is lifted (ordinate) and the parcel
origin pressure (abscissa). When the pressure is greater than the origin
pressure (on the second graph only), the quantity graphed is the buoyancy
(degrees C) of air that has first been saturated by the wet bulb process at
its origin level, and then descends pseudo-adiabatically.

If the user does not have NCAR graphics, other contouring routines can be
substituted for the NCAR graphics calls toward the end of the program. 

This program needs only to be compiled and run; no input values other than
the input sounding need be supplied.
