Decades of Mars observations show a pattern of regional dust storms arising in northern spring and summer. For instance the damage due to dust storms in China averages at about 65 billion per year source.
The dust could make it as far west as southern Illinois an expert says.
Where do dust storms come from. Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms or strong pressure gradients associated with cyclones which increase wind speed over a wide area. These strong winds lift large amounts of sand and dust from bare dry soils into the atmosphere transporting them hundreds to thousands of kilometres away.
Large global dust storms put enough dust in the air to completely cover the planet and block out the sun but doing so ultimately dooms the storm itself. The radiative heat of sunlight reaching the surface of the planet is what drives these dust storms. They can be called sand dust storms haboobs or sandstorms.
Here are 7 crazy facts about dust storms. This article relates the different views from specialists of the scientific expedition team for the exploration of the origin of sand-dust storms. They observed and examined on-site the ecological environment of places of origin for sand-dust storms and tried to find out causes of sand-dust storm and what harm it can cause in the hope of preventing and treating sand-dust storms in a more scientifically feasible way.
The specialists warn that in the next few years sand-dust storms. It begins in the Sahara where wind storms levitate enormous plumes of desert dust thousands of feet above the surface of the Earth. There in camel-colored wisps thousands of miles long the dust.
Strong northerly winds are causing dust storms in parts of the state. Authorities have warned residents of nine districts to be wary of the bushfire risk. The immediate economic impact of dust storms is significant but it doesnt rival major natural disasters that destroy entire cities.
For instance the damage due to dust storms in China averages at about 65 billion per year source. FordA single major earthquake can do damage to the tune of five times that figure. If you are traveling in a group do not venture off during a dust storm.
You can quickly become hopelessly lost. Members of the group should stay together and hold hands or lock arms. Some of the most famous dust storms of the Dust Bowl and similar conditions later were in fact synoptic scale events typically generated by a strong cold frontal passage with 14 April 1935 911 May 1934 19 February 1954 and 11 November 1911 being particularly vivid examples.
The researchers suspected that Saharan dust storms sometimes prevent disturbance waves from intensifying into tropical storms and then hurricanes. That Saharan dust keenly interests Dunion a research meteorologist from the NOAA Hurricane Research Division in Miami. He said The Saharan Air Layer is essentially a huge dust storm that can be the size of the continental United.
The dust could make it as far west as southern Illinois an expert says. In the meantime it will have a dampening effect on hurricanes. A giant storm of dust and sand from Africas Sahara is heading towards the Gulf of Mexico according to satellite images.
Tracking its movement meteorologists predict that it might travel over 5000 miles to make its way into the US in a week. And this holds good news as it might temporarily give Americans a break from the hurricane season. Describing the incoming storm Dr Dan Lindsey a.
Scientists know to expect big dust storms on Mars but the rapid development of the current one is surprising. Decades of Mars observations show a pattern of regional dust storms arising in northern spring and summer. In most Martian years nearly twice as long as Earth years the storms dissipate.
But weve seen global dust storms in 1971 1977 1982 1994 2001 and 2007.
