Study Guide Overview
This study guide covers atmospheric circulation, focusing on uneven solar radiation, convection cells (Hadley, Ferrel, Polar), pressure and wind direction, and the Coriolis effect. It explains how these factors interact to create global wind patterns and includes practice questions and exam tips.
#AP Environmental Science: Atmospheric Circulation - The Night Before
Hey there, future environmental champion! Let's break down atmospheric circulation. It might seem complex, but we'll make it super clear and easy to remember. Think of this as your ultimate cheat sheet for exam success. Let's get started!
#Uneven Solar Radiation & Global Heat Distribution
The Earth's tilt is the reason why we have uneven heating. The equator gets direct sunlight, while the poles get less. This difference in solar radiation drives all atmospheric and oceanic circulation patterns.
- Equator: High solar radiation = warmer temperatures.
- Poles: Low solar radiation = colder temperatures.
- The Goal: Earth's systems work to redistribute this heat, moving warm air towards the poles and cold air towards the equator.

Remember that heat transfer is a fundamental concept in environmental science. Uneven heating drives the movement of air and water, which in turn affects climate and weather patterns.
#Atmospheric Convection Cells
These are like giant conveyor belts in the atmosphere, moving air around the globe. They are key to understanding global climate patterns.
-
Convection Cells: These are loops of rising and sinking air, driven by temperature differences.
-
Hadley Cells: 0° to 30° latitude. Warm, moist air rises at the equator, cools, and descends as dry air around 30°.
-
Ferrel Cells: 30° to 60° latitude. These are driven by the...
