Worked practice questions

Wind blowing parallel to straight isobars, with gradient force balanced by Coriolis force, is the:

  1. Land sea breeze
  2. Valley breeze
  3. Geostrophic wind
  4. Katabatic wind
Show answer and solution

Correct answer: C. Geostrophic wind

1. It occurs 2 to 3 km up, free of friction. 2. This is the geostrophic wind. 3. Friction matters only near the surface. _Source: syllabus Fundamentals of Physical Geography, Chapter 10, Atmospheric Circulation and Weather Systems._

Wind circulation around a low-pressure centre is called:

  1. Anticyclonic
  2. Geostrophic
  3. Katabatic
  4. Cyclonic
Show answer and solution

Correct answer: D. Cyclonic

1. Around a high it is anticyclonic. 2. Around a low it is cyclonic. 3. Air converges and rises over a low. _Source: syllabus Fundamentals of Physical Geography, Chapter 10, Atmospheric Circulation and Weather Systems._

The tropical convection cell between the ITCZ and 30 degrees is the:

  1. Hadley cell
  2. Ferrel cell
  3. Polar cell
  4. Walker cell
Show answer and solution

Correct answer: A. Hadley cell

1. Air rises at the ITCZ to about 14 km. 2. The tropical cell is the Hadley cell. 3. It sinks at 30 degrees as a subtropical high. _Source: syllabus Fundamentals of Physical Geography, Chapter 10, Atmospheric Circulation and Weather Systems._
