What weather change is commonly associated with a frontal passage?

A frontal passage is typically associated with a significant change in wind direction, which is why the option indicating a wind change is correct. As a front moves through an area, it disrupts the local atmosphere, leading to shifts in wind as different air masses with varying temperatures and moisture content interact.

This change in wind can often be observed in the form of shifting gusts before and after the frontal boundary passes. For example, with a cold front, winds may shift from southerly to westerly, while with a warm front, the change may be from an easterly to a southerly direction. Such shifts can be indicative of the type of front passing through and can affect weather conditions significantly.

In contrast, temperature inversions are conditions where warmer air traps cooler air close to the surface, which does not specifically correlate with frontal movements. A decrease in humidity may occur in some cases but is not universally observed with every frontal passage. Similarly, increased visibility could happen with certain weather systems but is not a consistent result of every front's passing. Wind changes are the most consistent and observable result across various types of fronts.
