Today (6 November), eight women herders have been killed in central Mongolia due to snow storms, the country's National Emergency Management Agency. Snow and blizzards have caused icy roads and poor road visibility during weekend.

Snow and blizzards swept the western provinces of Zavkhan and Uvs and central parts of the country including the national capital Ulaanbaatar, and provinces of Arkhangai, Uvurkhangai, Tuv and Bulgan, with wind speeds up to 20 meters per second.

The southern provinces of Dundgovi and Dornogovi, the eastern provinces of Khentii and Sukhbaatar, and the northern provinces of Khuvsgul and Darkhan-Uul also experienced strong winds and snow storms.

Volatile weather is expected to continue in the coming days across large parts of the country, the agency said, warning the public, especially nomadic herders and drivers, to take extra precautions against possible disasters.

The Asian country's climate is strongly continental with long, frigid winters and short, warm summers.

One of the grandstands appeared to have its roof collapsed at the Interlagos circuit.
Chaos ensued at the Sao Paulo Grand Prix in Brazil during the third qualifying session. The storm made the roof of the grandstand collapse. No serious injuries have been reported. The Q3 was cut short.

Several people suffered minor injuries after the roof of the Porto Seguro grandstand near the final corner of the race track crashed down due to heavy wind and rainfall during the qualifying session for the Sao Paolo Grand Prix.

The sky turned from dark, and the wind started blowing violently in a matter of minutes, right in the middle of the Q3 qualifying session, the last of the three. That prompted the F1 marshals to cut the session short. With people still in the grandstand, the roof was ripped off and blown away by the wind.

The weather event came after torrential rainfall hit parts of Scotland.

According to National Geographic, waterspouts are similar to tornadoes but are usually smaller and less intense.

Five people have been killed after rivers burst their banks following torrential rain in the central Italian region of Tuscany, local authorities said on Friday, as Storm Ciaran continued to lash western Europe.

There had been fears that the River Arno could flood the historic city of Florence after nearby towns were swamped, but Tuscan regional president Eugenio Giani said the high water point had passed in mid-morning without major incident.

A bridge collapsed near the city of Pistoia, killing two people. Another person died in the town of Rosignano.

Question

Is the jet stream changing?

Researchers at Mainz University are investigating the jet stream to assess how its decadal variations could affect the occurrence of weather extremes in Europe.

Heavy precipitation, wind storms, heat waves — when severe weather events such as these occur they are frequently attributed to a wavy jet stream. The jet stream is a powerful air current in the upper troposphere that balances the pressure gradient and Coriolis forces. It is still not known whether the jet stream is really undergoing changes at decadal timescales and, if so, to what extent.

"There are various theories as to what we can expect from the jet stream in future. However, these are all based on highly idealized assumptions," said Dr. Georgios Fragkoulidis of the Institute of Atmospheric Physics at Johannes Gutenberg University Mainz (JGU). "Although it is quite clear that carbon dioxide emissions make a direct contribution to the global mean temperature, changes in the atmospheric circulation are highly uncertain due to the chaotic processes that govern its evolution."

The season's first snows have frosted the Rocky Mountains, the northern Plains, the Great Lakes and northern New England over the past week, resulting in the most extensive early-November snow cover in at least two decades.

On Wednesday morning, snow was on the ground in 17.9 percent of the Lower 48, according to the National Oceanic and Atmospheric Administration.

Locations from eastern Minnesota to western New York saw snow on Halloween — even enough to shovel in Minneapolis; Milwaukee; Muskegon, Mich.; and Buffalo. Areas downwind of Lakes Erie and Ontario were also blanketed early Wednesday, including Cleveland and Akron, Ohio, while several inches were anticipated along some of the west-facing slopes of the Appalachian Mountains.

This latest batch of wintry weather comes on the heels of two other storm systems that brought snow to the Mountain West, the northern Plains, the Midwest and northern New England over the past week.
