Stability Assessment » Convective Inhibition (CIN)
Question
Which of these two soundings has greater CIN?
A
B
Neither, CIN is the same in both
A is correct. CIN is substantially larger in sounding A. This results primarily from the isothermal layer at 850-800 hPa.
Incorrect. Compare the shaded areas below the LFC in the two soundings, then try again.
Incorrect. While CAPE values are similar, CIN values differ significantly. Compare the shaded areas below the LFC in the two sounding, then try again.
