Definition: Freezing Level

The freezing level is the lowest level in a sounding at which a temperature of 0°C is reported. (If the surface temperature is below freezing, then the surface level is the freezing level.)

Skew-T Procedure

From the surface, follow a 0°C isotherm upward until it crosses the temperature profile. That level is the freezing level.

This sounding comes from Bahrain and was retrieved from the JAAWIN website. A bold, blue line clearly denotes the 0°C isotherm, which crosses the temperature profile just above the 600 hPa isobar.
