Energy balance
General circulation
Main lesson
Coriolis parameter and inertial circles
Use this for “At 45° N a current moves at 0.2 m/s with no force but the Coriolis effect. What are f, the radius of its inertial circle and its period?”
The three circulation cells
Use this for “Which cell holds the trade winds, the westerlies and the ITCZ, and why are the subtropics dry?”
Climate variability
Main lesson
Warming trend from yearly anomalies
Use this for “Ten yearly temperature anomalies run 0.32, 0.41, 0.35, 0.47, 0.44, 0.52, 0.50, 0.58, 0.55, 0.63 °C. What is the warming trend per decade?”
Which orbital cycle
Use this for “A cycle of about 41,000 years swings Earth’s tilt between 22.1° and 24.5°. Which Milankovitch cycle is it?”
Climate models
Main lesson
Warming that lags the forcing
Use this for “The equilibrium warming is 3 K and the ocean’s response time is 30 years. How much has it warmed after 30 years?”
Warming with feedbacks
Use this for “Without feedbacks a CO₂ doubling warms Earth by 1.2 K. With a feedback factor of 0.6, what are the gain and the warming?”
Cost of a finer model grid
Use this for “A climate model has a 1° grid and 50 levels. How many columns and boxes does it have, and how much more does a 0.5° grid cost?”
Paleoclimate proxies (δ¹⁸O, ice cores)
