![]() Heavy winds called Derechos sometimes develop due to strong downdrafts along the border of a stationary front. They can reach speeds of 160 km/h (100 miles per hour), which can cause damage to infrastructure and endanger human life. When a high percentage of moisture is present in the atmosphere, heavy & persistent rain can lead to flooding in the region along the front. ![]() On occasion, a stationary front can lead to extreme events. This condition usually depends on the amount of moisture present in the air. It is not uncommon to find winds blowing parallel to the direction of a stationary front.Īnother characteristic of a stationary front is the distinct difference in temperature experienced on either side of this "fixed barrier." The mass of air behind the approaching warm front has a much higher temperature than the mass of air behind the approaching cold front.Ī stationary front is also often accompanied by overcast and dreary weather with persistent light precipitation that can last for days. The weather that accompanies a stationary front is not nearly as dormant as the movement of the front itself. What Weather Does A Stationary Front Bring? The latter usually occurs over a large open area like the ocean. The new forward-moving front can be a cold or warm front, depending on which of the air masses gained more strength.Ī stationary front can also eventually break up and dissipate entirely or develop into shear lines. It can lead to extended periods of dreary and miserable weather, as you will discover in the next section.Įventually, the front can start moving again as a result of one of the two air masses gaining strength or a change in wind direction occur. This stalemate leads to the development of a stationary front that remains in one location, sometimes for days on end. (It usually occurs when a cold front and warm front catch up with each other.) As already stated in the definition, a stationary front forms when two air masses meet, but neither one of the two is strong enough to displace the other.
