What are high-altitude high-velocity winds?

Answer 1

High-altitude high-velocity winds, often referred to as jet streams, are fast-flowing air currents found in the upper levels of the atmosphere, typically between 6 to 12 miles above the Earth's surface. These winds can reach speeds of over 200 miles per hour and play a significant role in weather patterns, influencing storm movements and temperature distributions. Jet streams are primarily driven by the temperature differences between polar and tropical air masses and are most prominent during winter months. They can affect aviation, climate, and weather forecasting.
