Another weather boundary that is displayed on this surface map, is a red line with semicircles designating a warm front. These changes occur in reverse order when the dry line retreats westward. A trough is not a boundary but an elongated area of lower air pressure. The signs vary continuously, depending on the changing weather-factors. When you're at a low elevation, you experience high atmospheric pressure because more of the atmosphere is pushing down on you. On a weather map, you will notice some lines that have semi-circles or triangles on either side, or both. State of Florida.com | Florida Traffic Signals They can also appear on upper air maps.
