Temperature/Levels » Equivalent Temperature (Te) Skew-T Procedure

  1. From the dewpoint at the given pressure, draw a line upward parallel to the saturation mixing-ratio lines. Also, from the temperature curve at the given pressure, draw a line upward along a dry adiabat until it intersects the line drawn from the dewpoint. Recall that this level is the LCL.
  2. From the LCL, follow a saturation adiabat upward to a pressure where the saturation adiabat parallels the dry adiabat. This is the pressure level where all the moisture has been condensed out of the sample.
  3. From this pressure, follow a dry adiabat back to the original pressure. The isotherm value at this point is equal to the equivalent temperature (Te).

In this example, air at 850 hPa with T = 10°C and Td = -8°C has an equivalent temperature of 17°C.
