Determining Stability » Potential Instability How Much Lift is Needed for Release of Instability?

Skew-T showing conversion of potential instability to conditional instability through ascent

In practical application, it is instructive to examine the minimum amount of lifting whereby potential instability may be released. This can be done by choosing the parcel with the highest relative humidity relative humidity in the layer of interest and lifting the parcel to saturation on the skew-T. This is the minimum lift required to initiate the release of potential instability.

For the 1000-800 hPa layer in this sounding, what is the minimum lift needed for the release of potential instability? Enter your answer in the text box below, then click Done.

Minimum Lift = hPa
