Question: 1 / 400

What characterizes downslope winds that occur at night?

Strong

Moderate

Weak

Downslope winds that occur at night are typically characterized as weak due to the atmospheric conditions that dominate during this time. As the sun sets and temperatures begin to drop, the cooling air at higher elevations becomes denser and starts to flow down the slope. This process tends to produce lighter winds compared to those experienced during the day when solar heating can create stronger thermal winds.

At night, the surface temperatures are generally cooler, and any winds produced are usually less intense because the thermal activity that fuels stronger winds is diminished. Additionally, terrain features and obstacles can further weaken these winds, contributing to their typically gentle nature.

In summation, the characteristics of downslope winds at night are defined by their weaker intensity, making this option the most accurate in describing the conditions of such winds.
