Which symbol represents a Warm Front on weather charts?

Warm fronts are shown on weather charts with a red line that carries semicircles pointing in the direction of the front’s movement. Those semicircles represent warmer air gradually advancing over cooler air, and this setup typically brings steady, widespread clouds and precipitation that can begin ahead of the front, followed by warmer air after it passes. That red line with semicircles is the symbol for a warm front. The other symbols correspond to different fronts: blue triangles on a line mark a cold front, alternating red semicircles and blue triangles on opposite sides indicate a stationary front, and a purple line with both symbols on the same side indicates an occluded front. Green squares along a line aren’t a standard front symbol.
