Record #cold in #Siberia

Record Cold Alert

On the last working day of the outgoing week, most of Siberia was in the high pressure field formed by the anticyclones – the Arctic and Kazakhstan. During the night and early morning hours, intensive cooling took place and instrumental observations of the weather were updated in a number of settlements in the region .

In the village of Novy Port, which is located in the Yamal-Nenets District, the thermometer fell to -3, which is 2.5 degrees lower than the long-term value, and became a new absolute minimum for September 13, the previous -2.9 degrees was observed 17 years ago. In Aleksandrovsky (Tomsk Oblast) it was -3.2 (4.4 degrees lower than the climatic norm), the previous record of September 13 -3 lasted 18 years. In the village of Mamakan (Irkutsk Region), the new absolute minimum temperature is -4, which is 0.6 degrees lower than the previous one recorded in 2003.

On the night of September 15, in the Yamal-Nenets Okrug and the Irkutsk Region, when clearing, frosts are expected to reach -6 degrees.

#UK could be hit by another ‘Beast from the East’ this #winter, say #scientists

Freezing weather in March 2018

Britain could be facing a new “Beast from the East” big freeze this winter, scientists have warned.

After studying sea temperatures and air pressures over the north Atlantic Ocean, climate experts have suggested January and February 2020 could be among the coldest for decades.

This would be caused by the jet stream – strong winds that move weather systems across from the Atlantic to Britain – deflecting southwards for weeks around Christmas, allowing freezing air to dominate the country, it is predicted.

The predictions for over four months’ time are one of the longest-range UK weather forecasts ever attempted.

Freezing weather in February 2018

Scientists from University College London have forecast an average temperature of 3.9C (39F) for January to February next year in central England – which they said was 0.5C below the 1981-2010 average for the same period.

The team, led by Mark Saunders, professor of climate prediction at UCL, wrote in a paper: “This would rank 2020 January-February central England as the coldest winter since January-February 2013.

“It would also rank January-February 2020 as the seventh coldest winter in the last 30 years, and the 23rd coldest winter since 1953.”

“There is a 57% chance the central England temperature will be colder than the 4.1C (39.4F) in 2018, thus making it the coldest January-February since 2013,” they added.

The 2018 “Beast from the East” happened as very cold air swept in from Russia.

It brought unusually low temperatures and heavy snowfall to large parts of the UK in late February and March last year.

Seventeen people died, including a seven-year-old girl, and temperatures plummeted to -17C in the Cairngorms in Scotland.

The possible new extreme freezing weather would contrast markedly with this July when the UK recorded its highest-ever temperature, which was 38.7C (101.7F) in Cambridge.

Not predicted: more #sea #ice than average in southern-most #Arctic first week of #August #2019

Hudson Bay weekly departure from normal 2019 Aug 5

Polar bear habitat update for the first week of August 2019 shows there is still more sea ice than average in Hudson Bay, the southern-most area of continuous habitation for this species. That certainly wasn’t part of the predictions of doom, especially since freeze-up in that region for the last two years has also been earlier-than-average which means a shorter ice-free season than we’ve seen for decades.

Despite ice coverage for the Arctic ice as a whole being marginally lower than it has been since 1979 for this time of year, sea ice for the first week of August was also above average around Svalbard in the Barents Sea and higher than the last few years in the Central Arctic, which is a critical summer refugium for polar bears that live in the peripheral seas of the Arctic Ocean, including the Chukchi (see photo below, taken in early August 2018).

Record #Cold In Parts Of #Russia

Record Cold Alert

August 7 was marked by new temperature records. Moreover, they were installed in the central regions of European Russia. The northern and eastern regions of the Central Federal District turned out to be the coldest, the average daily air temperature here did not reach the norm of 4 degrees. In some cities of the Yaroslavl region, it dropped so much that it set new daily records. According to the site ” Weatherand Climate, Rybinsk became the record-breaking cities, where the minimum temperature was 7.2 degrees, which is 0.1 degrees lower than the previous record held since 1982, and Pereslavl-Zalessky colder in the morning to 3.7 degrees, the previous record, 5.4 degrees, was also noted in 1982.

In the city of Vladimir, it got colder up to +5, which also became a daily record (the previous record, 5.9 degrees, and was noted here in 1982.)

On Friday, the temperature in these areas will approach normal, and again on weekends will lag behind it 1-2 degrees.

One of the most intense #winters in almost 50 years in #Peru

Cold Weather Alert

Lima is going through one of the coldest winters in almost 50 years , surpassing even the same season of 2018, confirmed the National Service of Meteorology and Hydrology (Senamhi).

As you know, winter in this part of the world officially began on June 21 at 10:54 am (Peruvian time) and will conclude, giving way to spring, on September 23 next at 2:50 pm We will have around 63 winter days.

According to engineer Lourdes Menis Álvarez of Senamhi, the winter of 2018 was one of the coldest in almost 50 years. However, the winter of 2019 has already surpassed it in intensity.

“Lima is currently recording minimum temperatures around 14.7 ° and 14.8 °. As for maximum temperatures, we are around 17.5 °,” Menis said in conversation with El Comercio .

“If we compare these reports with those of last year, we see that we are going through a slightly colder winter … We have temperatures 1 ° or 1.5 ° lower than those of 2018,” added the climatology specialist.

Why did the cold increase? According to Senamhi engineer, this is mainly due to the increase in humidity in the environment. “The recurrence of drizzles are being much greater than last year. Only in July there were already 12 days of drizzle, when it is normal to have only five … Normally the humidity is 92% and 95%; however, already we are registering humidity of up to 98%. On days with heavy drizzle, this has increased up to 100%, “he said.

In the opinion of the engineer Menis this type of cold winters are those that are recorded in the chronicles of the history of Lima. Only before the occurrence of phenomena such as El Niño of 2017 “we had already got used to having long summers and, practically, our winters were warm.”

The Senamhi monitors the weather in Lima through three weather stations. These are located in Callao, Jesús María and La Molina.
