What are high-elevation rivers of air that travel between 120 and 240 kilometers (75 and 150 miles) per hour in a west-to-east direction?

Answer 1

High-elevation rivers of air that travel between 120 and 240 kilometers per hour in a west-to-east direction are known as jet streams. These fast-flowing air currents are typically found in the upper levels of the atmosphere, particularly in the troposphere, and play a significant role in influencing weather patterns. Jet streams can vary in strength and position, affecting temperature and precipitation across different regions. They are primarily driven by the Earth's rotation and temperature differences between the equator and the poles.
