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.

https://www.eoas.ubc.ca/books/Practical_Meteorology/prmet102/Ch05-stability-v102b.pdf

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.
