Trough line weather
WebA trough of low pressure with significant weather will be depicted as a thick, dashed line running through the center of the trough and identified with the word "TROF" The symbol for a ridge of high pressure is very rarely, if at all, depicted Notes: The observations from various stations are plotted These are referred to as station models Cold fronts are depicted by blue line with triangles pointing in the direction of motion. Cold fronts demarcate the leading edge of a cold air mass displacing a warmer air mass. Phrases like "ahead of the front" and "behind … See more A warm front is the leading edge of a relatively warmer air mass replacing a colder air mass. A warm front is depicted by a red line with half-moons located on the side of the … See more Cold fronts typically move faster than warm fronts, so in time they can "catch up" to warm fronts. As they do the warm air mass is forced up … See more If the front is essentially not moving (i.e. the two air masses on either side are not moving perpendicular to the front) it is called a stationary front. A stationary front is depicted by an alternating red and blue line with a triangle on … See more
