Practice Questions

Question 1

Which of the following statements accurately describes the relationship between the pressure gradient force (PGF) and the Coriolis force (CF) in the formation of geostrophic wind?

Question 2

Given a constant pressure gradient, how would the geostrophic wind speed change if the latitude decreases from $60^\circ$ N to $30^\circ$ N?

Question 3

Which of the following atmospheric waves is primarily responsible for the long-range transport of heat and momentum in the mid-latitudes and exhibits westward propagation relative to the mean flow?

Question 4

In the context of atmospheric dynamics, what is the primary physical mechanism that drives the westward propagation of Rossby waves?

Question 5

Consider a situation where the pressure gradient force and the Coriolis force are in perfect balance, resulting in geostrophic wind. If the isobars are oriented east-west in the Northern Hemisphere, with lower pressure to the north, in what direction would the geostrophic wind flow?
