Temperatures have plunged to new lows in Europe where a week-long cold
snap has now claimed more than 220 lives as forecasters warned that the big
freeze would tighten its grip over the weekend. Read more here.
A
Jet stream anomaly caused a deadly cold snap in Europe, described the worst in
several decades has taken nearly 200 lives leaving thousands trapped. Many of the dead from one of the harshest
European winter in decades are homeless. Meanwhile, the same Jet stream anomaly
caused temperatures further north near the Arctic Circle and the US to be much
warmer than normal. Countries from Italy to Ukraine on one hand and on the other hand, upto to Greece
and Turkey on the East struggled to cope with temperatures that reached record
lows in some places.
UKRAINE:
Tens of thousands of people have headed to shelters trying to escape the freeze
that the emergencies ministry said has now killed nearly 100 people. Most of
them literally froze to death on the street, with only a handful making it to
hospital before succumbing to hypothermia, the ministry said. Shivering and
hungry, tens of thousands of Ukrainians have sought help in the more than 2,000
temporary shelters set up by the authorities to help the poor survive the
fearsome spell of cold weather.
ROMANIA:
Many people died overnight because of
the cold, bringing the overall toll to 22, the health ministry said. Schools
remained closed in some parts of the country as temperatures reached minus 31
degrees Celsius.
BULGARIA:
Mercury dipped to lows not seen in a
century.
LATVIA:
10 people have died around the capital Riga alone, with no figures available
for the rest of the country.
LITHUANIA:
A 55-year-old homeless man found in the ruins of an abandoned house in the port
city of Klaipeda became the ninth victim of the chill.
ITALY:
hundreds of people were trapped overnight on trains as freezing temperatures
and heavy snowfalls in the centre and north caused widespread disruptions on
roads, railways and at airports.
SICILY:
The cold has so far killed an infant in and a 76-year-old pensioner in Parma
during what forecasters say is the coldest weather in Italy in 27 years.
AUSTRIA:
An 83-year-old woman was found frozen to death in the woods after apparently
slipping on her daily walk and not managing to get up again, becoming the
country's second victim of the cold snap, officials said. In Serbia, the cold
has killed six people and trapped some 11,500 others, mostly in remote mountain
villages inaccessible by road.
SERBIA: Homeless people unable to secure one of the
140 spots in the capital's sole shelter took refuge in trolley buses and trams.
FRANCE:
Several regions have been placed under "deep
cold" watch; authorities banned trucks on several major highways where
the risk of snowfall and ice remained high.
UK:
The Met Office has issued its most serious cold weather alert of the winter so
far after overnight temperatures dropped to -9C in parts of the UK, with chilly
conditions set to continue into the weekend and some snow forecast.
GREECE: Forget
the usual images of Greece basking in hot sunshine reflecting on blue seas, and
imagine snow-covered mountains and sub-zero temperatures. Greece is in the grip
of arctic weather which has seen temperatures plummet well below zero. The ice
on the ground and the snow covered orange trees glimmer in sunlight which
belies the freezing condition
TURKEY: Extreme winter conditions have brought life
to a standstill across Turkey. The biggest freeze since 30 years has grounded
180 flights on Tuesday, and on Monday 200 flights were cancelled. The daily
life of the European side of Istanbul was mainly paralyzed today and snowfalls
are predicted to last until the weekend, with icy temperatures as low as Minus
27° Celsius in Southern Turkey. Meteorology officials have warned that snowfall
and blizzards are likely to continue uninterrupted until February 7.
So why this cold burst in February?
In general,
the La Niña causes radical Jetstream changes and you can click the arrow in the
video to watch Accuweather’s explanation. Moreover, the Arctic Oscillation (AO)
which was strongly positive till mid January overwhelmed the La Niña’s cooling
effect by keeping the winds spinning fast in the Arctic, not allowing the cold
southwards. But for last two weeks, the AO has flipped to its strongly negative
mode as shown below which unleashed the arctic blast into Europe.
The cold jet stream dipped in Europe and Asia, but is still
bottled up over North America. That's because another weather phenomena, called
the North Atlantic Oscillation (NAO) is playing oddball by staying positive and
keeping the cold away from the rest of North America. About 90 percent of the
time, the North Atlantic and Arctic oscillations are in synch. But not this
time, so much of the United States is escaping the winter's worst. But this can
change soon. The NAO index looks as if it is going to soon flip strongly
negative too.
India: Another Western Disturbance underway, temperature to drop early next week
India’s North-West, is right now receiving an
active western disturbance (WD) with rough weather implications for not just
the higher reaches but also the plains. On Thursday, an India’s Met Office
update confirmed the WD located the weather-making westerly system lying over
north Pakistan and adjoining Afghanistan. The system would start affecting the
western Himalayan region and adjoining plains from Friday onwards. As it
happened mid January, there is as simultaneous wave from exactly the opposite
direction (easterly wave) moving across the seawaters of the Bay of Bengal
aiming to hit south peninsular India from around the same time today.
The IMD has forecast heavy rain or snow at one or
two places over Jammu and Kashmir and Himachal Pradesh on Friday and Saturday. Importantly,
the forecast also mentions about the possibility of hailstorms lashing one or
two places over Punjab, Haryana, north Rajasthan and west Uttar Pradesh on
Saturday. A two-day forecast said that rain or snow would break out at a few
places over Jammu and Kashmir and at one or two places over Himachal Pradesh
and Uttarakhand on Friday and increase thereafter. From early next
week, temperatures in India should experience a significant dip.
