Extreme Temperatures
Frankfurt airport, Germany's main air hub, cancelled around 500 departing and arriving flights, representing 40 percent of its daily schedule.
The busiest airport in Europe, London Heathrow, scrapped more than 200 flights.
Heathrow said a decision was taken 24 hours in advance to cancel 130 flights due to predicted poor visibility, but problems elsewhere in Europe were having an impact too.
"The additional cancellations are because a number of airports elsewhere in Europe are experiencing problems so that has a knock-on effect for us," an airport spokesman said.
Heathrow has spent 36 million pounds ($57 million) on upgrading its snow-clearing equipment since 2010, when freezing temperatures and snow almost brought the airport to a halt in the approach to Christmas.
Freezing rain and snow also led to treacherous conditions on railways and roads, triggering numerous accidents.
Heavy snow brought its usual mixture of beauty, fun and serious disruption to most of the country on Monday as the cold front that turned southern England white on Sunday moved east and north.
Hundreds of schools were closed, disrupting some GCSE and AS-level exams, and there were cancellations and delays on roads, rail and in the air as bitterly cold winds added drifting to already deep falls and widespread ice.
Heathrow airport suffered worse disruption than expected with 175 flights cancelled by midday, well over the figure of 130 predicted earlier. Sunshine brought a rapid thaw but the total later crept close to the 260 cancellations of Sunday. The airport blamed poor visibility.
Gatwick and Birmingham airports were also badly disrupted and East Midlands and Robin Hood airports were closed to flights.
Heathrow has spent 36 million pounds ($57 million) on upgrading its snow-clearing equipment since 2010, when freezing temperatures and snow almost brought the airport to a halt in the approach to Christmas. Europe's number three airport, Paris's Charles de Gaulle, was also hit. France's civil aviation authority DGAC said it expected to scrap 40 percent of flights to and from Charles de Gaulle and Paris's other main airport, Orly, in a precautionary measure following heavy snowfall on Sunday. Even Munich, a city usually accustomed to taking snow in its stride, cancelled 161 flights at its airport as it grappled with the exceptional conditions.
Over the weekend extreme weather has swept across Europe from the UK to Spain, claiming lives and causing flight cancelations and power outages. The freezing temperatures have forced Europe to consume more gas prompting the spot price to reach $406 per 1000 cubic meter. Gas at Britain's National Balancing Point traded at $398.7 last week which was 8.5% higher than in first week of January.
However, Russia's Gazprom, which in 2011 provided 32% of total gas supplies to Europe, will not benefit much from the rise. Only 20% of Gazprom's gas exports to the EU were spot deals, Sergey Vakhrameev, analyst at Metropol told Vedomosti daily. Long-term contracts make up the majority of Gazprom deliveries, while spot supplies are only 7% of total exports, Vakhrameev added.
The combination of a stormy wind (100 km/h), the huge and intense snowfall and the fact that warmer air is coming in this afternoon is causing a very critical situation. Around 200 centimeters came down since Sunday and you can expect another 40-70 centimeters today.
Federal officials said that the measure, which was requested by the Chihuahua government, will allow authorities to access resources within the national emergency fund to cover food, clothing and health care needs among the affected population. Salvador Echavarria Campos, a meteorologist with Chihuahua's UEPC civil defense agency, said that the lowest temperature registered Thursday morning was minus 11 C (12 F) in the municipality of Bocoyna, in the state's mountainous region.
On Tuesday, UEPC director Luis Lujan Peña confirmed that the snow had cut off some 150 communities in the Sierra Tarahumara mountains. So far, official figures are that six people have died in Chihuahua and two others in the western state of Michoacan from causes linked to the low temperatures.
Muscovites woke up and found their cars, driveways and houses buried under a thick layer of snow, with city workers unable to get to smaller streets. Moscow's Yandex app showed traffic at level 10, the highest possible, as strong winds created blizzard conditions and built imposing snow drifts.

The frigid temperatures also caused delays and cancellations on major railway lines including the Eurostar train service, and transport authorities warned of further traffic disruptions with more blizzards forecast for Sunday.
In London, thousands of passengers were forced to camp out on the floors of Heathrow Airport overnight as hundreds of flights to and from the British capital were cancelled.
"There are lots of bodies lying around in the airport. If feels like there's been a natural disaster," Jerry Meng from Los Angeles, whose flight to New York was cancelled, told British broadcaster BBC.
