Which Atmosphere term is correctly associated with location: “generally found near the tropopause”, and also with “mainly flows from west to east”?

Correct Answer: Option B — Jet stream. Jet stream is correct because it is generally found near the tropopause. Jet stream is also associated with mainly flows from west to east. A further identifying fact is that Jet stream is mainly flows from west to east. Another useful fact is that Jet stream is associated with it strongly influences weather systems and aviation routes. Why the other options are incorrect: Option A — Trade winds: It is blow from subtropical highs toward the equatorial low and is associated with deflected westward by the Coriolis effect; those are the identifying facts of Trade winds. Option C — Westerlies: It is blow between subtropical highs and subpolar lows and is associated with generally flow from west to east; those are the identifying facts of Westerlies. Option D — Doldrums: It is located near the Intertropical Convergence Zone and is associated with surface winds are often light and variable; those are the identifying facts of Doldrums. Exam Takeaway: Link Jet stream with “generally found near the tropopause” and “mainly flows from west to east” for quick revision.
