Surface pressure systems tend to move in the same direction as the wind at 5500 m (18,000 ft)-the 500-mb level. The speed at which surface systems move is about double the speed of the winds at this level.

Question

Quizplus · Accepted Answer

Surface pressure systems generally move in the same direction as the wind at the 500-mb level (approximately 5500 m or 18,000 ft), but the speed at which surface systems move is typically less than the speed of the winds at this level, not double.
