Atmospheric Circulation and Winds

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the phenomenon where air and ocean currents curve due to the rotation of the Earth on its axis.

Front

What are convection cells?

Back

Convection cells are large areas of rising warm air and sinking cold air that help create global wind belts and drive atmospheric circulation.

Front

What are Polar Easterlies?

Back

Polar Easterlies are winds that blow from the polar regions towards lower latitudes, typically found in the polar regions.

Front

What are high pressure zones?

Back

High pressure zones are areas where cool, sinking air creates dry, sunny skies, occurring near the poles and at 30°N and S of the equator.

Front

What are Santa Ana Winds?

Back

Santa Ana Winds are local winds that bring hot, dry air from the Great Basin deserts over the mountains of Southern California, often causing extreme wildfire conditions.

Front

What is atmospheric circulation?

Back

Atmospheric circulation refers to the large-scale movement of air that distributes thermal energy across the planet, influencing weather and climate.

Front

What are trade winds?

Back

Trade winds are steady winds that blow from east to west in the tropics, forming part of the Earth's atmospheric circulation.

Front

What are westerlies?

Back

Westerlies are winds that blow from west to east in the mid-latitudes, playing a significant role in weather patterns.

Front

What is the role of the equator in atmospheric circulation?

Back

The equator is the region where solar heating is most intense, leading to rising warm air and the formation of low pressure zones.

Front

What is the difference between local winds and global winds?

Back

Local winds are winds that occur in a specific area due to local geographical features, while global winds are large-scale wind patterns that affect the entire planet.
