No data editing was done to avoid possible confusion. If parameters obtained in the analysis are bad due to bad data, they are left that way. These calculated parameters are presented with each skew-T plot provided. The details of the calculations used to obtain these parameters follow. In the case of the SUDS analysis the surface parcel temperature and dew point are taken as the average of that data over the lowest 50 mb of a sounding.
Positive values reflect stable conditions, negative values reflect unstable conditions.
Thus on the skew-T plot, the temperature trace is to the right of the moist adiabat originating at the LCL temperature and pressure. Graphically on a skew-T plot, in an unstable situation, above the LFC, the moist adiabat originating at the parcel's LCL temperature will be to the right of the measured temperature trace.
