Sounding plotted on skew-T diagram

Temperature and dewpoint curves are generated by first plotting temperature and dewpoint at each individual pressure level in the sounding. All mandatory and significant level sounding data should be plotted. Temperature points are then connected with straight lines between successive pressure levels, often using red. Dewpoints are similarly connected with straight lines, often using green.

The dewpoint temperature is the temperature to which a parcel of air at a constant pressure becomes saturated without any addition of water vapor. In other words, this is the temperature at ground level at which dew would be expected to form.
