Vertical Temperature Profile — Quiz

Test your understanding of vertical temperature profile with 5 practice questions.

Practice Questions

Question 1

Which physical principle explains why a rising unsaturated air parcel cools at approximately $9.8\,^\circ\mathrm{C/km}$ under adiabatic ascent?

Question 2

Using the approximate formula $\mathrm{LCL}\approx125\,(T-T_d)$ in meters, calculate the LCL altitude for an air parcel with surface temperature $T=24\,^\circ\mathrm{C}$ and dewpoint $T_d=14\,^\circ\mathrm{C}$.

Question 3

Why does the moist adiabatic lapse rate typically range between approximately $4\,^\circ\mathrm{C/km}$ and $9\,^\circ\mathrm{C/km}$ in the troposphere?

Question 4

What is the 'residual layer' in the context of the atmospheric boundary layer?

Question 5

A strong capping inversion is observed at 2 km altitude. How would this inversion most likely affect the vertical development of convective clouds?
