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 spikes pointing to its direction of travel. A warm front is shown as semi-circles in a traditional weather map, also pointing to its direction of travel.
The weather associated with an occluded front includes a variety of cloud and precipitation patterns, including dry slots and banded precipitation. Cold, warm and occluded fronts often meet at the point of occlusion or triple point. [28] A guide to the symbols for weather fronts that may be found on a weather map: 1. cold front 2. warm front
Occluded front depiction for the Northern Hemisphere. An occluded front is formed when a cold front overtakes a warm front, [10] and usually forms around mature low-pressure areas, including cyclones. [2] The cold and warm fronts curve naturally poleward into the point of occlusion, which is also known as the triple point. [11]
A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena. In surface weather analyses, fronts are depicted using various colored lines and symbols, depending on the type of front. The air masses separated by a front usually differ in temperature and humidity.
Warm fronts are usually preceded by stratiform precipitation and fog. The weather usually clears quickly after a front's passage. Some fronts produce no precipitation and little cloudiness, although there is invariably a wind shift. [19] Cold fronts and occluded fronts generally move from west to east, while warm fronts move poleward. Because ...

A cold front is the leading edge of a cooler mass of air at ground level that replaces a warmer mass of air and lies within a pronounced surface trough of low pressure.It often forms behind an extratropical cyclone (to the west in the Northern Hemisphere, to the east in the Southern), at the leading edge of its cold air advection pattern—known as the cyclone's dry "conveyor belt" flow.
