Coriolis Effect — Quiz

Test your understanding of coriolis effect with 5 practice questions.

Practice Questions

Question 1

Which pattern of wind circulation around pressure systems results from the balance of the pressure‐gradient force and the Coriolis force in the Northern Hemisphere?

Question 2

In the Northern Hemisphere, what is the net direction of Ekman transport relative to the surface wind?

Question 3

Which large‐scale atmospheric phenomenon arises primarily due to the latitudinal variation of the Coriolis parameter (the β‐effect)?

Question 4

What is the inertial period (time for one complete inertial oscillation) at latitude 45° N? (Use Ω=7.292×10^−5 s^−1 and T=2π/(2Ω sin φ).)

Question 5

For a synoptic‐scale motion with characteristic speed U=10 m/s over scale L=1000 km at latitude 45° N, what is the Rossby number Ro=U/(f L)?
