Front

How does temperature difference affect wind speed?

Back

The greater the temperature difference between air masses, the faster the wind blows.

Front

What is the jet stream?

Back

The jet stream is a fast-flowing air current in the atmosphere that influences weather patterns.

Front

What affects the path of a weather system in the United States?

La Niña is a climate pattern that describes the unusual cooling of surface waters in the eastern tropical Pacific Ocean, often leading to different weather patterns than El Niño.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air, due to Earth's rotation, affecting wind and ocean currents.
