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.

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.

Wind velocity and streamlines at an altitude of about 10 kilometers above the Earth's surface on the onset of a Western Europe heat wave (23 August 2016).
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."

Snow depth as of Wednesday.
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.

A winter storm on Oct. 26-27, 2023, halted the soybean harvest in areas of North Dakota.
Snow and unseasonably cold temperatures put fall harvest on hold across North Dakota and northwest Minnesota in late October.

A winter storm that moved across the northern Plains on Oct. 26-27 dumped as much as 18 inches of snow in the Walsh County, North Dakota, town of Lankin, according to the National Weather Service office in Grand Forks, North Dakota.

Other double digit amounts were 14 inches in Washburn and Harvey and 11 inches, in Minot and Williston. Further east, Leeds reported 8 inches and Larimore and Grafton reported 8.5 inches.

Low temperatures plummeted into the teens in the snow-covered areas after the storm and daily highs remained below freezing for several days the next week.

Meanwhile, some areas of North Dakota and northwest Minnesota in which temperatures were too warm for snow to develop, received rain, delaying harvest of the row crops.

Residents in some parts of the Eastern Cape, Free State and KwaZulu-Natal woke up to the breathtaking sight of snow covering nearby mountains and their gardens on Tuesday.

Barkley East, Elliot, and parts of Matatiele, south of the Drakensberg, have been turned into a winter wonderland.

Snow has capped the Sneeuberg, Winterberg and the Drakensberg mountains.

The SA Weather Service said other parts of the country that experienced snowfalls were the eastern parts of the Free State and mountainous parts of KwaZulu-Natal.

It sounds like the plot to a highly questionable adult documentary, but it's true. Hey, I'm just quoting Open Snow.

The 'Mass and Highlands got "24 inches in 24 hours."

Everyone in the 'hood here in the RFV has been posting and reporting pics of the measuring stick at AS this morning.

And in the wake of this white tsunami, that "stake" is lookin' mighty short.

Ancient landscape not seen for 14 million years discovered beneath Antarctic ice

Researchers have uncovered an ancient landscape that remained hidden beneath the East Antarctic Ice Sheet (EAIS) for at least 14 million years, using new satellite data and radar imaging.

This newly discovered landscape consists of ancient valleys and ridges, not dissimilar in size and scale to the glacially-modified landscape of North Wales, UK.

With ice-penetrating radar and satellite data, Durham University glaciologist Stewart Jamieson and colleagues mapped the topographic features of the landscape hidden beneath the East Antarctic Ice Sheet, to get a better understanding of how the ice sheet has fluctuated over time.

The researchers say preserved landscapes like this provide a rare opportunity to examine past ice conditions, but warming temperatures mean we are on track to return to the climate conditions that existed before the landscape was frozen, and it is possible that the East Antarctic Ice Sheet will retreat enough to change the landscape for the first time in at least 14 million years.

"The land underneath the East Antarctic Ice Sheet is less well known than the surface of Mars," explained study author Professor Stewart Jamieson in a statement. "And that's a problem because that landscape controls the way that ice in Antarctica flows, and it controls the way it might respond to past, present and future climate change."

The first major snowstorm of the season dropped up to a foot of snow in the Helena, Mont., area by Wednesday morning, canceling some school bus routes on the western side of the city as snow continued to fall throughout the morning.

Residents woke up to swirling snow, the sound of shovels on sidewalks and snowplows on pavement just days after temperatures rose into the lower 80s. Trees with orange leaves and Halloween decorations were weighed down with snow.

The National Weather Service warned of hazardous travel on snowy mountain passes and ice on some highways when snow initially melts and then freezes as road temperatures drop.


Comment: Update October 27

Krtv.com reports:
The first big snowstorm of the season was a good one! Most locations in the state at least a few inches of snow, and a few locations saw up to two feet. The snow began falling late Tuesday and continued throughout Wednesday and into Thursday.

Most of the snow accumulation is now done with, but roads are going to continue to be icy/snow-covered for the next couple of days, so please use extreme caution when driving and give yourself some extra time to get to where you need to go.

Snow stakes that measure how much fresh powder has landed show about 10 inches of snow at Aspen Snowmass since the start of an ongoing storm in Colorado. More snow is expected to fall into Friday morning.

This is on par with the prediction for the area, give or take a couple inches. Other ski areas in the Aspen area show about five to six inches on their snow stakes.

Nearby, Independence Pass, which reaches 12,095 feet of elevation, is also under a temporary closure. Closures of this nature are normal when wintery weather rolls through, with the seasonal closure for this iconic pass typically being put in place around November 7.

More snow is expected to keep falling in Colorado, totaling 18 to 24 inches in some mountainous areas in the northern portion of the state.

Those traveling mountain roads should proceed with caution, as roads will likely be slick and visibility may be limited.
