Warm-up: Atmospheric Circulation

What is wind?

• Large scale movement of air caused by differences in air pressure

• Large scale movement of CO2 caused by differences in air pressure

• Large scale movement of air caused by differences in temperature

• Large scale movement of temperature caused by differences in air pressure

If differences in air pressure produce winds, what can you conclude about temperature and air pressure based on the figure?

• As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind
• Warm air is denser than cold air is, creating an area of high pressure the produces wind.
• Winds flow from areas of low pressure to areas high pressure when temperature is warmer
• Air pressure decreases at night because temperature is lower, producing land and sea breezes
