Question: 1 / 400

What shift in wind direction is typically observed after a cold front passes?

Counterclockwise shift

No shift at all

Clockwise shift

After a cold front passes, it is commonly observed that the wind direction shifts in a clockwise manner. This shift is primarily due to the change in temperature and pressure dynamics that accompany the front. As a cold front moves through an area, colder, denser air replaces the warmer air that it displaces.

This transition creates a rise in pressure behind the front and often leads to a change in wind patterns. Typically, before the front arrives, winds may come from a southwesterly direction, but as the cold air mass pushes in, the wind direction shifts to come from the northwest in the aftermath of the front, indicating a clockwise direction around the high-pressure area that forms.

The clockwise shift is a fundamental aspect of meteorological patterns associated with cold fronts, making this answer the most accurate in the context of wind behavior following such a weather event.
