Meteorology · Fronts — Frontal Passage Wind Shift
In the Northern Hemisphere, the passage of a cold front is typically marked by:
- ARising temperature behind the front
- BA steady wind with no shift
- CA pressure fall behind the front
- DA sharp wind veer (clockwise shift), a pressure rise, and a temperature drop behind the front✓ Correct
Explanation
As a cold front passes in the Northern Hemisphere the wind veers (shifts clockwise, e.g., SW to NW), the barometer that had been falling begins to rise, temperature and dewpoint drop, and skies often clear to gusty, showery conditions behind the front.
