Anabatic winds are mainly created by ultraviolet solar radiation heating up the lower regions of an orographic area (i.e. valley walls). Due to its limited heat capacity, the surface heats the air immediately above it by conduction. As the air warms, its volume increases, and hence density and pressure decreases.
What causes Anabatic and katabatic winds?
Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column. ... Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a down slope wind.

How are katabatic winds formed?
Katabatic winds occur when air is cooled from below over sloping terrain. Such cooling causes a shallow blanket of air adjacent to the surface to become colder and therefore heavier than the atmosphere above, thus forming a thermally distinct layer that exchanges little energy with the overlying air.
