This image shows one of a handful of dust clouds that streamed over the Gulf of Alaska in autumn 2020. Dust storms from Africa’s Saharan Desert traveling across the Atlantic Ocean are nothing new, but the current dust storm has been quite expansive and NASA … New York, The Saharan dust storm is part of a regular meteorological phenomenon that sends dust from the Sahara Desert to the Gulf Coast of the United States, the Caribbean, and South America… Got any spaces left on that 2020 bingo card? Learn more about the science behind this expansive dust storm in the video that leads this article. A record-breaking Sahara dust storm that spread harmful air pollution across parts of North America in June 2020 was caused by winds linked to melting Arctic sea ice Measurements taken during two days of the storm noted 20 times more water released than via the classical process. Here's how to watch online. They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area. It was created from the Suomi NPP OMPS aerosol index. Massive Dust Storm on Mars 2020-11-13 - posted in Solar System Observing: For those near my latitude (133˚E), there is a massive dust storm on the ridge of Valles Marineris that started last night ans is still ongoing tonight; its transiting now, and Im in the process of imaging it: BQ An artist's image of an electrically charged dust storm on Mars. Image: Diana Francis. Perhaps the most striking example of the rapid process in action was the 2018 global dust storm that put NASA's Opportunity rover out of commission. Mars 2020: dust storm and freezing cold for Perseverance. US National Oceanic and Atmospheric Administration (NOAA) For nearly a week in June, a colossal dust storm raged over the Sahara that would impact air quality and weather conditions on the other side of the planet. Follow Nola on Facebook and on Twitter at @NolaTRedd. The dust clouds are so expansive and dense, that they can clearly be seen from satellite views and the International Space Station. On Earth, the hygropause serves as a barrier to trap water in the lower atmosphere. Satellite image of the June 2020 dust storm spreading from West Africa across the Atlantic. Sunday, June 28th 2020, 11:11 am - There's nothing usual about the magnitude of this Sahara Desert sandstorm that is almost circling the globe. It has made it to the U.S., will it touch Canada? 2020; November; Q&A: How Desert Dust Storms Supply Vital Nutrients to the Oceans; Q&A: How Desert Dust Storms Supply Vital Nutrients to the Oceans. "The classical process is like a slow and steady trickle of hydrogen into the upper atmosphere which varies little from Martian year to Martian year, while the process we describe is like a sudden splash of water into the upper atmosphere," Stone said. Mars is thought to have supported an ocean or two in its early days. Dust storms and summer heat may have removed an ocean's worth of water from Mars. Most of that water was lost to space. Above: The ADOT Dust Detection and Warning System on Interstate 10 between Eloy and Picacho Peak, in Tucson, Ariz. June 18, 2020. Join our Space Forums to keep talking space on the latest missions, night sky and more! The enormous cloud is visible from outer space -- and it's got meteorologists' attention because of what it will mean for people who live along the Gulf Coast. The same advice could be relayed to Texas, which seems to be the first area of the U.S. where the storm's effects reached. Japanese space capsule carrying pristine asteroid samples lands in Australia, Tissue chips and organoids: SpaceX is launching lots of science to space for NASA on Sunday, We may be in a 'golden age' of sample-return space missions. Researchers led by Diana Francis, at Khalifa University of Science … For example, one global dust storm lasting 45 days releases the same amount of … Martian dust storms parch the planet by driving water into space. But, the risks aren't too high. Dust storms can carry large amounts of dust, with the leading edge being composed of a wall of thick dust as much as 1.6 km (0.99 mi) high. Mars, which is also called the twin sister of Earth, once had the proper … Please refresh the page and try again. But they can happen at high latitudes, too, in places that are icy and dry. The mission will be to find traces of ancient life on the Red Planet and collect Martian dust for meteorological purposes before it returns to Earth. Schematic of weather dynamics that fueled June 2020 dust storm. Space photos: The most amazing images this week. During global and regional dust storms, which occur during southern spring and summer, water in the upper atmosphere dramatically increases. Dust storms are relatively common in places like the Sahara Desert. While dust storms block light and heat from reaching the surface of the planet, they warm the hygropause, weakening it and allowing more water to pass through. (Image credit: NASA/Goddard/CI Lab/Adriana Manrique Gutierrez/Krystofer Kim). Stone worked with his colleagues to use data collected by MAVEN on its deep dives into the atmosphere over more than two Martian years (a little less than four Earth years). Maps of the water content in the atmosphere of Mars suggest the Red Planet once had an ocean that covered 20 percent of its surface, a fifth of the planet. January 19, 2020 A gust of 94 km/h was recorded at Parkes about 6.30pm while a gust of 107 km/h was recorded at Dubbo about 7.45pm, the bureau said. Dust storms and summer heat may have removed an ocean's worth of water from Mars. By Nola Taylor Redd 19 November 2020. The winds could carry the dust toward and into Alabama and Georgia. The researchers found that the subtropical high was embedded in a circumglobal wavetrain, a chain of wind patterns that extended around the planet, and was present in the Northern Hemisphere for most of June 2020. A trough moving through central Australia on January 11, 2020, lifted up huge amounts of dust, creating a massive dust storm -- almost the entire width of the continent. The loss of the Red Planet's water slowly changed its atmosphere. (Image: © NASA/Villanueva/Mumma/Gallagher/Feimer et al.). The province could just experience some hazy conditions. The steady trickle of Martian water loss over the bulk of the year compared to the sudden splash during dust storms. The results were published on Nov. 13 in the journal Science. Dust and sand storms which come off the Sahara Desert are locally known as a simoom or simoon (sîmūm, sîmūn). Animated GIFs of the dust storm's activity: This animation shows the aerosols in the Saharan dust plume from June 15 to 25, 2020. A dust story in El Fasher, North Darfur. Japan is bringing pieces of an asteroid to Earth today. The latter even being a concern for healthy people. It affects all aspects of daily life in the region, including airline flights. In less than 100 days, the Perseverance rover sent by NASA will land on Mars. Space is part of Future US Inc, an international media group and leading digital publisher. Thank you for signing up to Space. Arpa C . The researchers estimated that the seasonal process, without taking dust storms into account, would strip Mars of a 17.3-inch-deep (44 centimeters) global layer of water over the course of a billion years. Dust storms make driving dicey, even for self-driving cars. These images of Mars show a very different view of the same hemisphere of the planet. The storm is being dubbed the “worst in the last 50 years.”, We flew over this Saharan dust plume today in the west central Atlantic. The newly inferred rapid release of water during the southern summer and during dust storms does not overturn the classical process, which continues to operate today. NY 10036. The image on the left, taken in May 2016, shows a clear atmosphere, while the one on the right, snapped in July 2018, reveals the global dust storm that shut down the Opportunity rover. The largest and thickest part of the plume is visible over the eastern and … (Image credit: University of Arizona/Shane Stone/NASA Goddard/Dan Gallagher). Getty. Such changes can be difficult to model because a small shift can be magnified over the 4.5-billion-year life of the solar system. It has made it to the U.S., will it touch Canada? The research reveals that summer dust storms can send water to the top of Mars' atmosphere, destroying the molecule and allowing hydrogen to escape into space. A … 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. Assuming a global dust storm like the 2018 event occurred once every decade, an additional 6.7-inch (17 cm) depth of global water would be lost in that time, with local dust storms each year contributing even more destruction. This is a natural weather phenomenon in Darfur which occurs regularly between March and July every year. Saturday, it looks like the dust will continue along the southeast states, touching Alabama, Georgia, and the Carolinas. During most of the Martian year, the two processes liberate roughly the same amount of hydrogen atoms that can escape into space, he added. Written By . By Paul Voosen Nov. 12, 2020 , 2:00 PM. This unusually powerful sandstorm -- dubbed a 'Godzilla' storm by some forecasters -- is even continuing strong into the U.S., providing some hazy days for parts of Texas and also affecting many of the southern states. MAVEN's Neutral Gas and Ion Mass Spectrometer (NGIMS) instrument samples air when the probe dips into the Martian atmosphere to an altitude of 78 miles (125 kilometers), which happens every 4.5 hours. During global dust storms, 20 times more water can be transported to the upper atmosphere. Rising Great Plains dust levels stir concerns By Roland Pease Oct. 20, 2020, 10:50 AM Earlier this month, a storm front swept across the Great Plains of the United States, plowing up a … © 2020 The Weather Network Pelmorex Weather Networks. Here you will find some more information on this matter. This wavetrain may have been caused by record-low Arctic sea ice extent observed in June 2020 … Because hydrogen is the lightest atom, some of the hydrogen atoms can reach speeds high enough to escape the pull of Mars' gravity and are stripped off into space. This graph shows how water in the Martian upper atmosphere varies over the year. In contrast, the previous models of how the Red Planet's water is lost allow for a slow seepage of water from the middle atmosphere through the hygropause and into space. "This process is slow and steady from Martian year to Martian year, so scientists have known for five to six years now that the classical model could not possibly be responsible for rapid variations in the [hydrogen] escape, which have been observed to occur on timescales less than a Martian year," Stone said. Martian dust storms fling water higher into the atmosphere than previously thought possible, helping to strip the Red Planet of its limited water and potentially contributing to the loss of an ocean's worth of water over billions of years, a new study finds. Damaging winds produced by thunderstorms across the state whipped up the dust storms, turning daytime into night in some towns Huge dust storms hit … Shares. National Oceanic and … "Mars has likely lost enough [water] to cover the planet's surface with an ocean tens to hundreds of meters deep, and loss rates must have been higher in the past.". There could also be risks of allergins when the dust settles. The warmer temperatures of the southern summer also heat up the atmosphere, making the hygropause more porous. — Col. Doug Hurley (@Astro_Doug) June 21, 2020 The dust is expected to hit Gulf Coast states such as Texas and Louisiana on Wednesday and … Under the classical model, most of the water in the middle atmosphere that is broken apart by sunlight falls back toward the surface. Credit: Arizona Department of Transportation / Associated Press. Amazing how large an area it covers! Two years ago, Mars went undercover. Saturday, it looks like the dust will continue along the southeast states, touching Alabama, Georgia, and the Carolinas. While previous studies have suggested that water could be transported above the Martian hygropause, the new research found a seasonal trend, as well as a link to dust storms, in the amount of water found in the upper atmosphere. But more investigation is needed to establish the exact link.” Godzilla resulted from a large-scale weather anomaly involving unusually strong north-easterly winds over the Sahara. But it does have a plus side. Only some of the new hydrogen molecules slip past the hygropause and into the upper atmosphere, eventually leaving the planet. WOMAN VS. Pencil in "another Dust Bowl in the Great Plains." "During a global dust storm, the new process we describe produces [hydrogen] atoms at a rate that is 10 times that of the classical process," Stone said. The storms do get close to Manitoba, though they will likely miss. But the water that could have once kept the planet's surface habitable was lost over the eons, and scientists have been searching for the cause. Saharan dust storm 2020 fills the air, but has a plus side ‘Historic’ Saharan dust fills the air from Africa to the United States. Long window for life on Mars: Hundreds of millions of years? The risks that are associated with sandstorms of this magnitude include visibility and respiratory issues. Get breaking space news and the latest updates on rocket launches, skywatching events and more! This beast of a dust storm looks like it will have the energy to almost fully circle the globe before it subsides in Portugal. Future US, Inc. 11 West 42nd Street, 15th Floor, They also say that people should stay inside and drink lots of water. “In my view, it is not just by coincidence that the Arctic sea ice extent was the lowest on record in June 2020 and the most intense dust storm from the Sahara occurred also in June 2020. Once the water condenses, it stops traveling upward. The haboob (həbūb) is a sandstorm prevalent in the region of Sudan around Khartoum, with occurrences being most common in the summer. ICY SLOPE: YOU CAN LAUGH, WE'VE ALL BEEN THERE. A study from University of Utah researchers and their colleagues finds that atmospheric dust … You will receive a verification email shortly. Sand and dust storms are common meteorological hazards in arid and semi-arid regions. Last Updated: 30th November, 2020 12:58 IST Big Dust Storms May Have Been Responsible For Making Mars Barren; Reveals A New Study Scientists found that big dust storms in Mars stripped this planet of its natural water source. Meteorologists are closely following some mega-sized dust plumes that are … We use cookies on this site to improve your experience as explained in our Cookie Policy. The Caribbean meteorologists recommend that everyone should wear a mask, which should already be happening from coronavirus. "Once water reaches the upper atmosphere, it has a lifetime of about four hours," Stone said. Dust plumes blow over the Cape Verde (Cabo Verde) islands, imaged by NASA’s Terra satellite on June 18, 2020. NGIMS doesn't directly measure water, because hydrogen and oxygen in the atmosphere can combine inside the instrument to create the molecule. Martian dust storms … The winds could carry the dust toward and into Alabama and Georgia. Visit our corporate site. The dust plume was Caribbean island hopping over the weekend and into the beginning of the week, fully blocking out the sun along its path. However, global and local dust storms flinging water into the upper atmosphere produces hydrogen atoms roughly 10 times faster than the classical process, Stone said. When water vapor reaches the colder patch of sky, it condenses from gas to liquid to form clouds. The trough is expected to bring showers and storms to the southeast into Sunday morning, January 12. When water molecules reach the upper atmosphere, they react with charged particles, or ions, and split into hydrogen and oxygen atoms. Stone and his colleagues estimated that the monster dust storm caused Mars to lose as much water in 45 days as it typically loses during one Martian year, which is 687 Earth days long. "The seasonal and dust storm-mediated delivery of water to the upper atmosphere could have played a substantial role in the evolution of the Martian climate from its warm and wet state billions of years ago to the cold and dry planet we observe today," the authors wrote in the new study. The sandstorm is currently sitting in the Gulf Coast and in southeast areas of the US. I wrote this piece because of the sheer volume of social media posts and questions from people saying, “I have never heard of dust storms like this making it … Follow us on Twitter @Spacedotcom and on Facebook. And if you have a news tip, correction or comment, let us know at: But Stone and his colleagues are confident that the seasonal shifts and dust storms played an important role in removing the water. Sunday, June 28th 2020, 11:11 am - There's nothing usual about the magnitude of this Sahara Desert sandstorm that is almost circling the globe. Instead, NGIMS relies on ions, which it separates by mass so that researchers can identify them and calculate the amount of water in the upper atmosphere. You can reject cookies by changing your browser settings. "Dust storms inject a sudden splash of water into the upper atmosphere," study lead author Shane Stone, a graduate student at the University of Arizona, told by email. The dust plume moved from Africa’s west coast over the Atlantic Ocean into the Caribbean Sea and up through the Gulf of Mexico. Was the ‘Godzilla’ dust storm connected to low Arctic sea ice? Now, researchers using NASA's Mars Atmosphere and Volatile EvolutioN spacecraft, or MAVEN, have learned that powerful summer dust storms may carry water above the hygropause, a cold layer in the atmosphere that traps water lower down.
