Skew-T Procedure
- From the dewpoint at the given pressure, draw a line upward parallel to
the saturation mixing-ratio lines.
Also, from the T 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.
- 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.
- 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
