Wind barbs are a useful indicator for locating low pressure centers on surface weather maps.
Since winds flow in a counterclockwise direction around low pressure centers , look for a group of stations where the wind barbs reflect this type of wind pattern. So when trying to find a low pressure center on a surface weather map, use the wind barbs to find a counterclockwise wind pattern and the low pressure center will be found near the center of circulation.
