ERAS
TXT1 Generate a X-Section perpendicular to the thickness contours, from low
TXT2 to high thickness values, in the area of interest (e.g. north of the
TXT3 warmfront).  CSI is indicated where the geostrophic momentum surfaces
TXT4 are less vertical than the Theta-E surfaces.  If Theta-E decreases with
TXT5 height, the atmosphere is convectively unstable and upright convection
TXT6 is favored.  The area of CSI must have a relative humidity >= 80% to be
TXT7 important.
