One symbol of an occluded front is the TROWAL symbol with alternating blue and red lines similar to a cold/warm front junction

A cold front is diagrammed as blue spikes pointing to its direction of travel. A warm front is shown as red semi-circles in a traditional weather map, also pointing to its direction of travel. An occluded front is a combination of those two signs: they are indicated on a weather map either by a purple line with alternating semicircles and triangles pointing to the direction of travel, or by red semicircles and blue triangles pointing to the direction of travel. On the other hand, a TROWAL is diagrammed on [[weather]] maps by the junction of blue and red lines like the junction of cold and warm fronts aloft.

A wide variety of weather can be found along an occluded front, with heavy thunderstorms and tornadoes possible, but usually, their passage is instead associated with a drying of the air mass. Additionally, cold core [[Funnel cloud|funnel clouds]] are possible if the [[wind shear]] is significant along the cold front. Small isolated occluded fronts often remain for a period after a low-pressure system has decayed and disappeared and these create cloudy conditions with patchy areas of rain or showers.

However, the clouds and precipitation are not really the location where the projection on the Earth's surface of the occluded front is, but it is with the TROWAL position.
