The jet stream is a fast-flowing river of air high in the atmosphere that can significantly influence weather patterns. It is typically associated with high winds and stormy conditions because it marks the boundary between cold and warm air masses.

When the jet stream dips or meanders, it can lead to the development of low-pressure systems, which are commonly associated with stormy weather, including rain, thunderstorms, and even severe weather events. The strong winds within the jet stream can also contribute to the intensity and movement of weather systems, leading to turbulent conditions at the surface.

In contrast, conditions like stable and calm weather, dry and hot weather, or snowy and freezing temperatures do not accurately reflect the active weather patterns accompanying the jet stream. While these conditions can occur in the broader context of weather influenced by the jet stream, they are not characteristic of the turbulence and disturbances typically associated with its presence.
