1. VIRTUAL TEMPERATURE T V (Virtual Temp.) is the temperature a dry air parcel would be if its pressure and density were equal to a given moist air sample. T V is the scaled quantity of Temperature (the only variable that is independent of pressure and density in the Ideal gas law). T V allows us to use the dry air equation of state for moist air T V is used to adjust CAPE soundings in order to assess convective potential energy from Skew-T log-P diagrams.

4. Interpretation and Conclusion When T v is calculated using the method involving the vapor pressure (e), then we get fairly realistic values concerning the virtual temperature. However, when T v is calculated using the hypsometric equation, the values calculated are very different from the expected values. These values are enormous in comparison to the vapor pressure method and suggests an enormous amount of water vapor in the atmosphere. This could indicate an error in calibration for one or both instruments measuring/recording the barometric pressure at the stations. This could also mean that there is an error in the elevations used in the calculation. Perhaps the sensors are at different heights than is listed on the website? (i.e. on top a building or measurements are not exact)
