A derecho (pronounced "deh-REY-cho") is a widespread, long-lasting wind storm accompanied by a band of quickly moving showers or thunderstorms. These storms are typically caused by a large scale disturbance in the atmosphere that produces strong winds and heavy rain or snow. In the United States, they are most common in the winter months from December through February.
Derechos are often fatal because they can bring down power lines which cause power outages that can lead to more damage if you don't have back up batteries or generators. Also, falling trees can injure people. Flooding from the heavy rains may cause roads to become impassable.
Derechos are classified into two types: straight-line winds and circular winds. Straight-line winds occur when cold air is pulled away from the center of a storm system and over land. This creates winds that move east to west at considerable distances from the center. Cirrostratus clouds and iceberg crystals are examples of phenomena associated with this type of wind storm.
Cirrus clouds are very high altitude clouds that look like sheets or layers of ice due to their flat appearance against the sky. They usually form at heights between 10,000 and 20,000 feet (3,048 - 6,090 meters).
Derechos are fast-moving thunderstorm bands with high winds. Winds may be as powerful as those encountered in storms or tornadoes! These winds, unlike hurricanes and tornadoes, move in straight lines. These storms are known as "derechos." The Spanish word for "thunderbolt" is "trombón." Thus, derecho means "right-handed thunderbolt."
A derecho is a large scale wind event that can cause significant damage when it moves across land. They usually develop over water but can occur over any type of surface. Because they are so widespread, derechos are often deadly. They can travel thousands of miles without changing direction or strength and have a major impact on the environment and economy of their path.
Derechos are different from other types of severe weather events such as hurricanes and tornados because they do not have a specific center. A derecho is defined by its edge - where there are strong winds blowing in one direction. This could be anywhere from an area of concentrated activity such as a vortex or cavity of low pressure to as far as 100 miles away from any visible features. There may even be isolated areas within the edge that experience no winds at all. Derechos also tend to last for several hours or more. After the main event has passed, another derecho is likely to form in another part of the region if conditions are right.
Derecho means "right-hander" in Spanish. A derecho winds from the right direction. A derecho is defined as a strong westerly wind that occurs during summer months across North America.
A derecho is a violent windstorm that can cause damage and death. These storms usually develop over water, but they can also occur over land. They usually last for hours or days and can be seen on radar images. There are two types of derechos: tropical and nontropical. Tropical derechos occur in association with tropical systems, while nontropical derechos occur at other times of the year. Nontropical derechos can affect any part of the world, but they tend to be weaker than their tropical counterparts.
Tropical derechos get their name because they generally follow a pattern of coming from the southwest and then moving northeast. This is different from most other windstorms which come from the west and move east. The term "derecho del niño" (the child of the sea) is used to describe these powerful storms that can bring flooding and high surf. Children often see them as fireworks going off in the sky.
Noun. A storm characterized by strong, severe winds but no precipitation cyclone. What is a dust devil? Gale. What is the difference between a dust devil and a gale? A dust devil is usually not as strong or long-lived as a gale. They can be very dangerous though so you should avoid them if possible. A gale warning means that there is a chance that a serious thunderstorm with hail, high winds, and tornadoes will form in the area. If this warning changes your plan, get ready for it! Check out our Gales and Dust Devils article to learn more about these phenomena.
Dust devils are small patches of swirling sand and dirt driven by wind speed differences across a landscape. They often appear near mountain ranges or around buildings. Because they are only a few feet tall and reach speeds up to 35 miles an hour, they can be a danger to people. When they die down, go inside! Failing that, try to find shelter in a building or under a vehicle. If you're caught outside when a dust devil is active, stay away from its edge because you don't want it to take you with it when it spins up.
