Video: Jet Stream simple definition.
Imagine you're trying to navigate through a crowded shopping mall on a busy weekend, where people are moving at different speeds and directions. This situation is similar to how the jet stream operates, as it is a fast-moving band of wind that flows between the slower-moving layers of the troposphere and the stratosphere, much like trying to find a clear path amid the bustling crowd. Just as finding a fast-moving lane among shoppers can significantly speed up your journey through the mall, planes can utilize the jet stream to travel faster and more efficiently across long distances.
