Atmospheric Thermodynamic Diagrams for Meteorology

Obtaining various types of atmospheric thermodynamic diagrams is difficult. Skew-T ln-p diagrams are most often used in this country, but I find Stuve (or pseudo-adiabatic) diagrams to be simpler for students to understand. Therefore, I have developed IDL procedures for plotting Stuve and T-phi (tephigram) diagrams. These procedures plot the pressure, temperature, dry adiabatic, saturated adiabatic, and saturated specific humidity lines of the diagram. In addition the procedures can plot the temperature and dewpoint of an input sounding.
