What global wind affects the US the most?

The global wind that affects the U.S. the most is the Westerlies, which are prevailing winds that blow from west to east in the mid-latitudes. These winds play a crucial role in shaping weather patterns and storm tracks across the continental U.S., influencing everything from precipitation to temperature. Additionally, the Jet Stream, a fast-flowing air current within the Westerlies, further impacts weather dynamics by guiding storm systems and affecting seasonal weather variations.
