Weather tracker: Cold air over warm waters brings heavy snow to Japan

Prefectures in north hit by falls of up to 30cm in a day as similar weather pattern affects parts of north America

Heavy snow fell across northern Japan on Thursday, with the prefectures of Hokkaido, Aomori, Yamagata and Niigata particularly affected. Accumulations of 20-30cm over a 24-hour period were recorded across the affected areas, with local totals of more than 30cm near Aomori City.

The snowfall was a result of heavy showers generated by a cold airmass moving in from the north-west across the relatively warm waters of the Sea of Japan. This resulted in warming of the lowest levels of the atmosphere, leading to rising motion and convective shower development caused by the increased moisture. Ascent was further aided by the mountainous terrain across northern Japan.

Weather tracker: lake-effect snow blankets parts of north-east US

There was significant snowfall in five states downwind of the Great Lakes, including 4ft in western New York state

As meteorological autumn drew to a close at the end of last week, parts of the north-east of the US saw substantial snowfall thanks to a phenomenon known as “lake-effect snow”.

This occurs when cold air passes over relatively warm lake waters, causing the layer of air near to the surface to absorb heat and moisture. Warmer than the air above it, this layer of air then starts to rise, cooling and condensing into clouds that deposit snow on the windward side of the lakes in extremely localised bands.

Four killed and flights cancelled as heavy snowfall blankets Seoul

South Korea’s capital has been hit by some of the heaviest snowfall in a century, with dangerous conditions wreaking havoc on transport

South Korea grappled with heavy snowfall for a second day on Thursday, with dozens of flights cancelled, ferry operations suspended and at least four people reported dead in a bitter winter, though conditions showed signs of easing.

Thursday’s snowfall was the third-heaviest in capital Seoul since records began in 1907, the Yonhap news agency said, citing city data. The previous day broke all snowfall records for November.

The Korea Meteorological Administration said 16.5cm (6.5 inches) of snow fell by 7am on Wednesday, compared with Seoul’s previous record of 12.4cm on 28 November 1972. It was the heaviest snowfall since records began in 1907, the KMA said.

Finland exports snow-saving mats to ski resorts hit by climate crisis

Preserving previous year’s snow for start of season can combat increasingly unpredictable winters

Before the arrival of electric fridges and freezers, people across Finland would saw a block of ice from a river or lake before the spring thaw, thickly cover it in an insulating layer of sawdust and stack it in barns, pits or ice cellars to protect produce from the warm air of the summer months.

Amid global heating and increasingly unpredictable shorter winters, a modern twist on the traditional jään säilöminen (ice preservation) technique is now being touted as a way to save Europe’s struggling low- and medium-altitude ski resorts.

Australia’s ski season could melt away early as snowfall drops to nearly half the average

August should mean peak snow depth, Jindabyne worker says, but early blast of spring threatens ‘catastrophic’ premature end to season

Australia’s snow season has begun to melt away early as unseasonable warmth cuts snowfalls to almost half the average for this time of year, experts say.

A global-heating fuelled early blast of spring weather means the season may have peaked early, with snow fields melted by warm temperatures and washed away by showers.

‘We may not have snow’: Australian ski season opens with a whimper

Mt Buller had the country’s only ski-on chairlift operating on season’s opening day on Saturday – but snow is forecast for the week ahead

It was a grassy start to Australia’s ski season, with one resort trying to remain upbeat “although we may not have snow on the ground” and a few pockets of human-made alternatives to play on elsewhere.

As global heating cuts Australia’s snowfall ski season may go downhill, report warns

‘The webcams do not lie,’ says Annalisa Koeman, whose family has been operating a mountain lodge for decades

Bookings have been slow ahead of the ski season at the mountain lodge in Thredbo that Annalisa Koeman’s parents built in the 1960s and have run ever since.

Last ski season started with some good snow falls “but it went downhill from there. It was a disastrous end. The ski lifts closed two weeks early,” says Koeman, managing supervisor at Kasees Apartments and Mountain Lodge.

‘Brutal’ Arctic blast expected to bring frigid temperatures to North America

Extreme cold warning issued in Canada as US forecasters warn of wind chills in Texas and major snow in midwest and east coast

A “bitter” blast of cold Arctic air is set to bring dangerously frigid temperatures to swaths of North America, forecasters have warned.

In Canada, frigid Arctic air is being pushed from the Northwest Territories down into the province of Alberta, where Environment Canada has issued an extreme cold warning. The largest city, Calgary, could see temperatures plummet to -34.6F (-37C) on Friday, reaching a daytime high of -23.8F (-31C). This would mark the coldest January day in two decades for the city. Over the weekend, strong winds could make temperatures feel closer to -58F (-50C). In these conditions, experts say exposed skin can succumb to frostbite in less than a minute.

Weather tracker: Nor’easter drenches US south-east coast

Up to 127mm of rain falls on Florida and gusty winds and flash flooding hit parts of Georgia and South Carolina

Chances of white Christmas in UK grow smaller as climate crisis takes toll

Parts of UK have more recently gone decades without Christmas snow, and in the past it was more hardship than dream

Bing Crosby may have been dreaming of a white Christmas, but it seems such nostalgia might end up becoming a thing of the past in the UK. Not only do records reveal that some parts of the UK have at times gone decades without a yuletide flurry, but experts say the chances of a white Christmas are becoming ever smaller as a result of the climate crisis.

According to the Met Office, a Christmas in the UK is white if even one snowflake is observed falling somewhere in the 24 hours of 25 December. Last year was, technically, a white Christmas in the UK, though none of the Met Office observation stations reported snow lying on the ground.
