Temperature/Levels » Convective Condensation Level (CCL) Skew-T Procedure
To determine the CCL on a sounding, start at the surface dewpoint, proceed upward along the saturation mixing-ratio line until this line intersects the temperature profile on the sounding. The level of the intersection is the CCL.
To determine the CCL on a sounding, start at the surface dewpoint, proceed upward along the saturation mixing-ratio line until this line intersects the temperature profile on the sounding. The level of the intersection is the CCL.
In this example, air at the surface with a dewpoint of 0°C would have a CCL of 750 hPa.
Note: When the moisture content in the near-surface layers varies significantly, an average moisture value of the lower layer may be used in place of the surface-parcel moisture value in computing the CCL.
