![]() ![]() They can sometimes cause a period of thunderstorms. Warm fronts bring steadier, lighter rain or snow in front of them, which can last from a few hours to several days, and warmer, drier air as the warm front passes. They gently settle over the cold front and move it out of the way. ![]() Warm fronts move more slowly than cold fronts, and are associated with less severe weather. The warmer air lifts up and over the colder air. Warm front: warm fronts occur when a warmer air mass approaches a colder air mass.On weather maps, cold fronts are marked with the symbol of a blue line of triangles (icicles) pointing in the direction of travel.Ī sea breeze is a form of a localized cold front. Depending on the time of year and geographic location, cold fronts can come in succession every 5 to 7 days. Strong cold fronts can set off atmospheric disturbances such as thunderstorms, squall lines, tornadoes, high winds and short duration snowstorms ahead of the moving cold front and cooler, drier weather as the front passes. The colder air, being denser, cuts a wedge under the less dense warmer air, lifting it and finally overtaking it. Cold front: cold fronts occur when a colder air mass approaches a warmer air mass.There are four main types of weather fronts: Weather fronts can also be affected by geographic features like mountains and large bodies of water, especially at the lower levels of the atmosphere. This movement is due to the Coriolis effect, caused by the Earth spinning about its axis. They are generally guided by the jet stream and travel from west to east. Weather fronts are often closely associated with atmospheric pressure systems. When a weather front passes over an area, it is marked by changes in temperature, wind speed and direction, atmospheric pressure, and often a change in the precipitation pattern. In meteorology, a weather front is a boundary between two air masses with differing characteristics (e.g., air temperature or humidity). ![]()
