← GeographyWhich airflow deflection results from upper troposphere coriolis?
A)Westward-blowing mid-latitude jet stream✓
B)Eastward-blowing equatorial trade winds
C)Increased polar cell thermal intensity
D)Weakened subtropical high pressures
💡 Explanation
The Coriolis effect deflects air masses to the right in the Northern Hemisphere, because the latitudinal pressure gradient's poleward air movement is deflected eastward by the Coriolis force, therefore causing westerly jet streams rather than other directions due to surface friction.
