La Niña and El Niño Effects

The video tutorial covers the jet stream, prevailing westerlies, Gulf Stream, El Niño, and La Niña. It explains how these atmospheric and oceanic phenomena influence weather patterns, particularly in North Carolina. The jet stream separates warm and cold air masses, while prevailing westerlies move weather systems from west to east. The Gulf Stream warms coastal climates, reducing snow likelihood. El Niño and La Niña are climate patterns affecting global weather, with El Niño increasing precipitation and La Niña leading to more hurricanes.

What is the primary direction of the jet stream's flow?

• East to West
