Wind barbs are useful 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. For example, a counterclockwise wind pattern was observed in the states of Nebraska, Iowa, Minnesota and South Dakota (highlighted by the red arrow). ![]() The low pressure center was located near the center (similar to the center of a whirlpool) with winds flowing counterclockwise around it. ![]() So when trying to find a low pressure center on a surface weather map, use the wind barbs to identify a counterclockwise wind pattern and the low pressure center will be found near the center of circulation.
