Question

Sounding plotted on skew-T diagram

What is the 900-hPa equivalent temperature (Te) in this sounding?

Te = °C

The correct answer is about 23°C.

From the 900-hPa temperature, draw a line upward along a dry adiabat. From the 900-hPa dewpoint, draw a line upward along a saturation mixing ratio line. From the intersection of these two lines, draw a line upward along a saturation adiabat to a level where this adiabat is parallel to a dry adiabat. From this level, draw a line downward along a dry adiabat to 900 hPa. The value of the temperature where this line intersects the 900 hPa isobar is 23°C = Te.
