 Let's go over some skew-tea basics just to make sure everyone is on the same page. Who uses skew-tea provided by UCAR? The lines will be the same as those on skew-tea produced by other organizations, but the colors may be different. The horizontal blue lines of pressure levels in millibar are hyperpastas. The temperature lines are tilted 45 degrees to the right and are in degree C. Dry adiabats, which indicate constant potential temperature, are the red lines curving upward to the left and they are marked in degrees Kelvin. The moist adiabats, which indicate the temperature change of a saturated air parcel, are the green dashed lines curving to the left and eventually becoming parallel to the dry adiabats. They are marked in degree C. The saturated water vapor mixing ratio is plotted with golden dashed lines and has units of grams per kilogram of dry air. Of course, this is just a water vapor mixing ratio if the temperature is higher than the dew point. Off to the right is the wind speed and direction at different altitudes. Plotted on this diagram are the temperature, the red solid line, and the dew point, the green solid line, both taken from a radio song.
