Meteorology · Ocean Currents — Weather
A warm ocean current such as the Gulf Stream affects marine weather by:
- ALowering air temperature and suppressing fog
- BPreventing storm development
- CWarming and moistening the overlying air, often producing fog where it meets cold air✓ Correct
- DHaving no effect on the atmosphere
Explanation
Warm currents heat and humidify the air above them; where warm-current air meets a cold air mass or cold water, advection fog is common (e.g., the Grand Banks). Currents also influence storm tracks and intensity.
