What direction do anabatic winds flow?

Anabatic winds are a phenomenon associated with localized heating of the Earth's surface, particularly in mountainous areas. These winds occur when solar radiation warms the slopes of a mountain during the day. As the slopes heat up, the air in contact with the ground also warms and becomes less dense. This warm air then rises up the slopes of the mountain due to buoyancy.

Understanding the behavior of warm air is crucial in aviation, as the characteristics of local winds can significantly influence flight operations. Anabatic winds can improve lift for gliders and reduce turbulence when flying in mountainous regions. The other wind types, such as katabatic winds, flow downwards and have different mechanisms and effects. Thus, the direction of anabatic winds flowing up the slopes is fundamental to understanding how air moves in relation to terrain.
