In a Surface Anticyclone?

Where the air pressure is high at the surface in an anticyclone, the air above it descends. As the air descends, the pressure rises (because there is more atmosphere above) and so the temperature of the descending air rises. In this case, evaporation usually exceeds condensation and so cloud droplets don't form.

In what direction does wind spiral in a surface anticyclone in the southern hemisphere?

In the northern hemisphere an anticyclone rotates in the clockwise direction, while it rotates counterclockwise in the southern hemisphere. The rotation is caused by the movement of colder higher pressure air that is moving away from the poles towards the equator being affected by the rotation of the earth.

What happens in an anticyclone?

Anticyclones are the opposite of depressions - they are an area of high atmospheric pressure where the air is sinking. As the air is sinking, not rising, no clouds or rain are formed. ... In summer, anticyclones bring dry, hot weather. In winter, clear skies may bring cold nights and frost.
