Beyond the snow and some downed tree limbs, the weekend blizzard left another, more unusual calling card, as Vineyard fields were strewn with cylindrical pieces of snow.

The meteorological phenomena are called snow rollers. According to the National Weather Service, snow rollers are formed by strong but not too-strong winds and light snow falling on a layer of smooth, crusted-over old snow.

A small piece of snow is picked up by the wind and, as it rolls along, it collects more snow and becomes cylindrical in shape, sometimes with a hole extending lengthwise through the center. It's a bit like an oblong base of a snowman made by the wind. Snow rollers are said to be as large as a foot in diameter.

Snow rollers are rare, the weather service said, because of the combination of conditions required for them to form.

Snow has been reported across forested upland areas in northern Laos as the extreme cold snap and associated precipitation persisting across much of Indochinese Peninsula since Sunday begins to ease, China's Xinhua news agency reported.

Temperatures in the low single digits Celsius during the day and around zero degrees or below at night since Sunday were accompanied by snow across elevated areas of the country's northern provinces.

The cold snap led to a temporary three-day suspension of domestic flights by the national carrier Lao Airlines between the capital Vientiane and the airport servicing the province of Oudoumxay while flights to other affected provincial centres faced delays, state-run media Vientiane Times reported.

In the province of Phongsaly, three-day extended leave was provided to public servants except police and defence personnel until Wednesday to help minimise the risks to life from unnecessary travel.

Residents in many parts of Mexico might decide to remain in their homes for this long weekend as heavy rains, strong winds, some snow and cold temperatures are forecast for many regions.

In fact, the national Civil Protection office has declared an "extraordinary emergency" in 446 municipalities in 23 states, brought on by cold front No. 34 and the eighth winter storm of the season.

The declaration will make resources available for the emergency supply of food and blankets to an estimated half a million people from Chihuahua in the north to Chiapas in the south.

The cold front´s mass of polar air is covering much of the country, guaranteeing cold to very cold weather for the weekend. Sleet or wet snow are forecast for areas 3,500 meters above sea level in the State of México, Tlaxcala, Puebla, Hidalgo and Veracruz and winds gusting to 70 km/h in the Isthmus of Tehuantepec.

Heavy snowfall has left thousands of people without electricity and Nova Scotia power estimates it could take until midnight before crews are able to restore electricity to many homes in the northern part of the province, many of which have been in the dark since Friday evening.

About 51,800 customers were without power at 7:30 a.m. Saturday. The outages affect about two dozen communities and range from Yarmouth to Dartmouth, Tatamagouche to Sydney.

While some areas such as Bridgewater are expected to see power back on around noon Saturday, service to parts of Guysborough isn't expected to return until 5:45 a.m. on Sunday.

The Department of Transportation says crews are working to clear and salt roads, some of which received as much as 30 centimetres of snow.

It is advising that the main roads in Cape Breton are still covered in snow and visibility is poor.

Friday night Nova Scotia Power said the nor'easter's impact was interfering with crews' ability to repair power lines as the heavy snow pushed trees onto them.

Turkey grappled on Tuesday with cold weather and heavy snowfall that led to the cancellation of flights and ferries in İstanbul and that covered many provinces in the rest of the country, Cihan news agency reported on Tuesday.

The inclement weather caused a number of car accidents, and some schools were forced to close. Authorities warned drivers to take extra care due to the poor weather conditions.

Flights and ferries canceled in İstanbul

Snowfall hit İstanbul's higher elevations early on Tuesday and spread to the rest of the city by the afternoon. Teams from the İstanbul Metropolitan Municipality and district municipalities salted the roads as a precaution against ice. Many İstanbul residents and visitors enjoyed the snowfall in historic areas such as Sultanahmet and popular tourism spots like Taksim Square.

Turkish Airlines (THY) and the İstanbul Ferry Lines (İDO) announced on Tuesday that certain flights and ferries were canceled due to the harsh weather conditions.

İDO canceled all its intra-city ferry services in İstanbul due to sea conditions. Some of the inter-city ferries, including the Kadıköy-Yenikapı-Bursa ferry and the Yalova / Kartal ferries, were also cancelled.

THY cancelled 143 flights to and from İstanbul and warned of further disruption in the coming days, as the city braces itself for heavy snow on Wednesday.

Pegasus Airlines, Atlasglobal and Onur Air also cancelled 22, 10 and six flights, respectively, due to the snow.

The number of farm animals killed in the record-low cold snap since last week rocketed to more than 8,900 - 11 times the figure released two days earlier, agriculture officials said on Wednesday.

Mountainous Son La Province replaced Quang Ninh Province in the previous report to become the hardest-hit locality with 2,756 animals frozen to death. This accounted for 38 per cent of the total.

Dead cattle, goat, horses and pigs were found across seven communes in Son La, one of which was Van Ho Commune, where snow fell for the first time in decades.

The northwestern province of Dien Bien was the second hardest-hit, with 641 out of 7,134 farm animals killed.

Climate fraudsters exposed by new monsoon study

India's monsoon is in no danger of catastrophic collapse in response to global warming and air pollution, two atmospheric scientists said today, refuting earlier predictions that the monsoon could shut down within 100 years.

The scientists at Yale University in the US who used computers to model the Earth's atmosphere, land and oceans have found that the expected changes in the monsoon will not abruptly alter their strength or their water volume.

Their results contradict earlier forecasts by scientists at the Potsdam Institute for Climate Impact Research in Germany portending frequent and severe failures and even a breakdown of the monsoon, which is critical to India's food, water resources and economy.

"Our models show that monsoon rainfall will change smoothly in response to rising greenhouse gas concentrations, air pollution, and changes in land use," William Boos, an associate professor at Yale University told The Telegraph.

"We should expect changes in the monsoon rainfall in response to changes in the global mean temperature in the coming decades, but there is no reason to expect those changes to be abrupt," Boos said.

The earlier modelling exercises had predicted that the monsoon, under the influence of global warming and air pollution, would experience a "tipping point" that would lead to a sharp drop in rainfall over India.

Boos and his colleague Trude Storelvmo have now shown that the theory and models that were used to predict such "tipping points" had omitted a key term in climate behaviour, ignoring the fact that air cools as it rises in the atmosphere.

The scientists described their results this week in the Proceedings of the National Academy of Sciences, a US research journal.

"It's bloomin' incredible" say botanists: More than 600 species of British flowers were in bloom on New Year's Day - usually it's 20-30

Nature Studies: In a normal winter botanists would expect no more than 20 to 30 plants to have been in flower


It's unheard-of: after the warmest and wettest December on record, more than 600 species of British wildflowers were in bloom on New Year's Day 2016, a major survey has shown.

In a normal cold winter, botanists would expect no more than 20 to 30 types of wild plants to be in flower in the British Isles at the year's end - species such as daisy, dandelion and gorse.

But a survey by the Botanical Society of Britain and Ireland (BSBI) has discovered that on 1 January, no fewer than 612 species were actually flowering, including some from late spring and high summer - an occurrence which seems to be without precedent, and has left plant scientists astonished.

"It's incredible," said Kevin Walker, the BSBI's Head of Science. "I've never seen anything like it."

Just like December's astounding weather regime of record rainfall and warmth, the mass out-of-time flowering is suggestive of a substantial climatic shift. "It is what might be expected with climate change," Dr Walker said.

The appearance of many familiar and well-loved springtime species was a complete surprise: cowslips and cow parsley were both recorded four months early, normally appearing in April, while yellow archangel, bulbous buttercup and red campion are all expected in May.
