Forecasting Near Anticyclones
generally fair weather

A high pressure center is represented on a weather map by a blue "H" and air diverges outward from a surface high. With air moving away from this region, air must sink from above to replace it. This sinking motion leads to generally fair skies and no precipitation near the high.

Winds flow clockwise around a high pressure center in the northern hemisphere (above). Temperatures are dependent upon the location relative to the high. Northerly winds associated with an approaching high are likely to result in colder temperatures while southerly winds found on the backside of a high, or once a high has passed through, typically result in a warming trend.
