Earth Changes
Wind-blown flames have raced across more than 1,000 square miles since Sunday, killed 11 people and forced about 1,900 others to evacuate.
But the snow -- containing dust or sand from the desert regions of northern China -- could pose a health hazard, the country's meteorological office warned.
"It's tough to say whether it's yellow sand mixed in snow or if it's snow mixed in yellow sand," a met official told Reuters.
A high concentration of the dust particles prompted the weather bureau to issue a yellow dust warning for the second time in three days.
South Korea frequently gets sand or dust storms, but a yellow snow storm is very rare.
The huge wooden poles splintered in two about 1 p.m., some crushing cars, and fell across all four lanes of the highway in what many said looked like a hurricane scene - or a disaster movie.
"This was a cross between 'War of the Worlds' and 'Earthquake,' " said Bernie Baker, contest director for the Triple Crown of Surfing who had been at the Buffalo's Big Board Surfing Classic in Makaha.
According to new research, the ability to dance may have been a factor in survival for our prehistoric ancestors, who used their moves to bond and communicate with each other when times were tough.
A study published in a recent issue of the Public Library of Science's genetics journal, suggests that, as a result, today's creative dancers actually share two specific genes. Both genes are associated with a predisposition for being good social communicators.
The violent weather started during the weekend with a line of storms that spawned tornadoes and downpours from the southern Plains to the Ohio Valley.
On Monday, a second line of storms raked the region, with rain, hail and fierce wind tearing up trees and homes from Kansas through Indiana, and blizzards to the north cutting off power to thousands and shutting down schools in South Dakota, Minnesota and Wisconsin.
Popularly called the butterfly effect, this aspect of chaos theory made Lorenz and others realize that predicting weather with pinpoint accuracy will never be possible.
But scientists are getting closer.
A tornado tore through the mobile home park she co-owns Sunday night, flipping over one of six occupied homes and killing a 39-year-old woman inside.
"There's not a lot of damage to the homes people live in," Rank said Monday, crying while sipping coffee in the dim candlelight of her kitchen. But "it really bothered me that a girl had to lose her life."
Early reports show more than 100 twisters touched down in a weekend wave that stretched across five states, from Oklahoma to Illinois. Nine of the ten dead were in Missouri.
"It's just amazing how devastating it is," said Mayor Tim Davlin of the Illinois capital of Springfield. "It looks like the pictures we saw a couple months ago after Katrina."
The violent weather was driven by a powerful low-pressure system over the Midwest that pulled warm air out of the Gulf of Mexico. The same phenomenon caused powerful winds that drove deadly wildfires across Texas over the weekend.
Ready or not, here it comes.
It is being spread much faster than first predicted from one wild flock of birds to another, an airborne delivery system that no government can stop.
For some reason, the snow that fell in the densely populated northern regions after a powerful cyclone had acquired a pink color of varying tints.
Experts at the local meteorology centre said sand from neighboring Mongolia was to blame for this unusual natural phenomenon.
Before it arrived in Maritime, the cyclone passed Mongolia, where sand storms had been raging in the desert.
"The winds of the cyclone embraced dust particles that colored the fallouts," the experts said.
February's yellow snowfall with a strong odor and an oily texture was observed on Russia's Far East island of Sakhalin. The color, odor and texture of the snow may have been a result of environmental pollution caused by the island's oil and natural gas industry.
However, experts do not rule out this could be caused by volcanic activity.
