High-pressure systems are generally associated with calm and sunny weather due to the descending air they produce. As air cools in a high-pressure area, it sinks and warms up, leading to clear skies and stable atmospheric conditions. This stable environment discourages the formation of clouds and precipitation, which contributes to the pleasant weather typically linked with high-pressure systems.

The other options describe weather patterns more commonly associated with low-pressure systems or other atmospheric phenomena. Stormy and windy weather usually arises in low-pressure systems where air is rising, causing instability and cloud formation. Cloudy and wet conditions accompany low-pressure areas that can lead to rain or storms. Lastly, extreme temperature variations often occur along fronts or in areas of rapidly changing weather systems, rather than in the consistent and stable environment provided by high-pressure systems. Therefore, the calm and sunny weather reflects the characteristic stability and clear skies associated with high-pressure areas.
