A line of red semicircles indicates a warm front on a weather map
Explanation:
Weather fronts are those visible colorful lines that we see moving across weather maps. They represent boundaries that separate two air masses of different air temperatures and humidity. A good example of weather fronts are warm fronts. A Warm frontal type is warm air that moves and advances rapidly towards the cold air to replace the rather cooler air that stands in its path. It sort of collides with the cold air. When this happens, the weather becomes more humid and warm. It is symbolized by a red curved line with red semicircles. The red semicircles are pointed towards the direction of the warm air.
