A study by the University of Utah suggests that dust threatens "the largest snow on Earth"


SALT LAKE CITI – A study by the University of Utah shows that dust can endanger "the biggest snow on earth".

In a study published on Environmental Research Flags on Friday, researchers report that the presence of dust accelerates snowball speed.

Geography teacher Mekenzi Skiles is the lead author of the study, which focused on land in Alpine, Utah.

"As if you wear a black shoe on a hot day, all the darker snow-like dust-absorbs more sunlight and accelerates melting," the study's press release said in a press release.

For plots in the Alpine, researchers have determined about 50% of the total dust received by it came from one dust that occurred on April 13, 2017. Additional sunlight absorbed as a result of dust caused snow over the past.

The team used computer modeling to determine the origin of dust and said the winds brought dust from hot spots in the Great Lake Lake lake.

The study identified such a focal point as a relatively new source of dust due to historically low levels of the lake.

"The Great Salt Lake is important that there is no water, there is no policy of maintaining the level of the lake," Sike wrote in a press release. "As the lake refuses, dust is expected to become more and more frequent Everything that affects snow can have economic and hydrological consequences. And now one of the dust regions is right next door. Can we do something about this by adopting a policy that maintains a minimum level lakes? "

Skiles said that while dust is naturally occurring, human factors play a role in its distribution.

"In most people, dust is a natural aerosol," said Skiles. "But the magnitude and frequency of dust in the air is influenced by human activity, the change in the area makes dust more likely to be picked up by the wind." We know that since the rise of the West, dust has increased in the air. At the same time, due to the water withdrawal upstream, the level of the lake also decreases, revealing even more dust. "
