Static-Stability Practice
0) Given the plotted sounding. View or print it.
1) On your own, determine the Lapse-rate Name for each layer from the sounding plotted above.
Choices: subadiabatic , adiabatic , superadiabatic .
If you are uncertain, then review Chapter 5 Atmospheric Stability, section 5.7.1.2, Table 5-1.

After you have first tried it on your own, then compare to the answers.
.
2) View or print the original plotted sounding again.
On your own, determine the Static Stability vs. height from this Sounding.
Use the Parcel (Apex) Method to include the non-local effects.
If you are uncertain, then review Chapter 5 Atmospheric Stability, section 5.7.1.1.

Choices: stable , neutral , unstable .
After you have first tried it on your own, then compare to the answers.
.
3) Note that for determining whether the flow will become turbulent or
not, you must always use the parcel (apex) method to include the
non-local effects of unstable air. By comparing your previous two
answers, you can see that the layer lapse-rates give an incorrect
determination of static stability and turbulence.
