Which effect results when seasonal shifts modify jet stream position relative to a mountain range?

💡 Explanation

When the jet stream shifts, wind is forced to ascend the range due to orographic lift, causing precipitation on the windward side and creating a rain shadow effect on the leeward side because air loses moisture, resulting in adiabatic warming. Therefore, orographic lift induced rainshadow is the result, rather than Coriolis changes, cell boundary shifts, or thermal gradient decrease, all of which require different mechanisms.
