Where is the jet stream typically found?

• A. Near the Earth's surface at the equator
• B. In the stratosphere above the ozone layer
• C. Deep within the ocean
• D. Typically found in breaks in the tropopause

Answer: (D)

Jet streams are narrow bands of strong winds that ride high in the atmosphere right at the boundary between the troposphere and the stratosphere. They form where there’s a big horizontal temperature difference—usually at mid- to high latitudes—creating a sharp pressure gradient that drives fast winds. Because they sit along this boundary, they’re found in breaks or folds of the tropopause, the sheet that separates the turbulent weather layer from the calmer layer above. So you won’t find them near the surface or deep in the ocean, and they aren’t deep in the stratosphere where the ozone layer mainly lies. Think of the jet stream as a fast, wavy ribbon along the edge of the troposphere—the breaks in that boundary are where the winds become the strongest.
