What is a physiological effect of a cold front passage on temperature?

A cold front passage typically leads to a marked and immediate change in weather conditions. One of the primary physiological effects observed is a sudden drop in temperature. As the cold front moves through an area, it displaces warmer air that was present before its arrival. The colder air mass that follows can lead to an abrupt cooling of the atmosphere.

In addition to the temperature drop, the transition brought about by a cold front is often associated with an increase in wind speeds. This is due to the pressure differences created when the denser cold air pushes underneath the lighter warmer air. The increased winds can contribute to the feeling of a more pronounced chill, further enhancing the physiological effects of the temperature drop.

The other options do not accurately reflect the behavior of temperatures following a cold front. For example, a gradual increase in temperature or a steady decrease with no wind change would not characterize the typical dynamics associated with a cold front. Hence, the correct choice effectively captures the expected conditions during the passage of a cold front.
