Which type of wind flows downslope becoming warmer and dryer?

The type of wind that flows downslope and becomes warmer and drier is known as a katabatic wind. Katabatic winds occur when cold air, often from high-altitude areas, descends down a slope due to gravity. As the air descends, it compresses and warms up, resulting in a dry wind. This phenomenon can be observed in various geographical settings, especially in mountainous regions and during nighttime when the ground cools the air.

Understanding katabatic winds is important in aviation and meteorology because they can affect weather patterns and conditions at lower elevations. The presence of these warming and drying winds can impact visibility and may influence flight plans.

In contrast, a land breeze is a nighttime phenomenon where air moves from land to sea, typically cooler and more humid. A valley wind is usually associated with the heating of the valley floor, causing air to rise rather than flow down slope. Monsoon winds, on the other hand, are seasonal winds that bring significant changes in wind direction and precipitation, not specifically focused on downslope flow or temperature changes.
