[quote="radon1"]Forecasters called June 29 the coldest day in Moscow for 70 years[/quote]

[quote]Forecasters called June 29 the coldest day in Moscow for 70 years
The temperature on the eve of the day rose to plus 11 degrees, with the climate normal at plus 22-23 degrees, experts said. Similar indicators, according to their data, became “cold anomaly”

Recorded on the eve of June 29, temperatures have become the lowest in at least the last 70 years. This is stated in the message on the website of the weather center project.

According to weather forecasters, the maximum temperature, which was recorded the day before at the base Moscow weather station ENEA, did not exceed plus 11 degrees. At the same time, the climate daily norm at this time of the year is 22–23 degrees of heat, the specialists recalled. Thus, the indicators recorded on the eve, according to their estimates, became the “cold anomaly”.

The temperature, comparable with yesterday, is specified in the message of “Meteonews”, on this day it was recorded only in 1996 (then the thermometers rose to plus 12.2 degrees) and in 2003 (13 degrees heat). Lower this day for all the time of observations (since 1948) the temperature in Moscow dropped only the day before, experts said. Such weather, according to their data, is characteristic for autumn, namely the end of September - the beginning of October.

That “ such a cold ” in the capital during the daytime hours on June 29 was not the last 71 years, RBC was previously confirmed by leading specialist of the weather center “Phobos” Yevgeny Tishkovets. The fact that the thermometer bars on the eve of the day did not exceed 11–13 degrees of heat in the capital is also evidenced by the materials on the website of the Hydrometeorological Center.

However, experts are not in a hurry to forecast a similar decrease in the temperature of the heat, which was observed in Moscow in June. “Moderate warming at the beginning of the upcoming week will be replaced by another decrease in temperature with a high probability of frequent rains,” the message of Meteorovosti says.

The fact that warming will come to the capital early next week, RBC was told earlier by the Deputy Head of the Situational Center of Roshydromet Anatoly Tsygankov. According to him, from July 2 night temperatures will be plus 12–15 degrees, and daytime temperatures will be plus 20–25 degrees.

Can someone explain why this is happening in conjunction with the high heat levels in continental Europe? . It seems to be the opposite of North America in the winter now, whereby the cold mass front is pushed southward while the northmost regions are heating up more than usual.

Basically the cold air that was over the Arctic Ocean shifted south over Moscow which caused the air over western Europe to shift north which pulled the hot Sahara air mass over western Europe.

Unlike North America, Europeans mostly live without air conditioning. At least that was the case when I lived there for 10 years in the 80's From my recent visits it seems to still be the case.

If you are in your 80's in an apartment with no air conditioning and you get those extended 37 degree heat waves many will die. That was the case in the 2003 heatwaves. Mostly older folks living in apartments and homes with no air conditioning.

But our buildings, unlike those in large parts of the US are built of sound concrete/brick/stone based materials.
They tend to be good heat insulators and incidentally it keeps buildings during summer rather cool.
So there is not much need for airconditioning.
I don't know what are american standards of building but based on photos documenting one particularly horrible tornado in Joplin in 2011 I have concluded that residential homes there are built of paper, cardboard, plasterboard and other light weight products of rather inferior quality.
Only public buildings are built well and these were the only ones which have offered some meaningful resistance.
One way or another at my home we had nice 20-22*C inside while outside was 32-35*C in a shadow and much more in direct sunlight for several days. No air conditioning, though we can draw to our badroom air which have passed via underground basement to cool it.

You are quite right. Even new multi-story condominium blocks can have walls composed of studs and gypsum board (drywall) even if the floors are concrete. You can hear your neighbor breathe. A lot of apartment buildings are all-wood glorified houses with 2x4 studs and drywall or the walls and 2x8 joists with drywall ceilings and some flooring planks for floors. So if you are "lucky" and get some 4 hours of sleep clown living above you who scurries most of the night keeping you awake you are just like millions of other lucky apartment dwellers waiting for the lease to expire to move. For detached private houses the situation is better since you can find some accommodation for noise from the rest of the family. For semi-detached houses you are back to listening to your neighbor breathe. There are even TV shows where they try to fix these transparent to noise walls with specialized gypsum board and sound deadening insulation.

That is true and a very good point. And yes, most new development home in the US are aluminum or wood framed, particle board, dry wall. No cement blocks, flimsy. Hurricane proned areas have building codes that basically just add metal straps to secure the flimsy walls and roof structure.

29 degrees C. at the delta of rivers at 71 degrees NL, draining a large part of the Taiga where temperatures are climbing up to 36 degrees and more.
The Ob and Yenisey, Taz drain roughly half of the Asian part of Russia, even some south of the border, Kazakstan...looks like almost 3000 by 3000 km wide.
Up to 9 million sq km in a heatwave that will wash out whatever is left of the sea ice in the Kara sea.

Climate change
During the last quarter of the twentieth century, the zone of latitude occupied by the boreal forest experienced some of the greatest temperature increases on Earth. Winter temperatures have increased more than summer temperatures. The number of days with extremely cold temperatures (e.g., −20 to −40 °C (−4 to −40 °F) has decreased irregularly but systematically in nearly all the boreal region, allowing better survival for tree-damaging insects. In summer, the daily low temperature has increased more than the daily high temperature.[54] In Fairbanks, Alaska, the length of the frost-free season has increased from 60–90 days in the early twentieth century to about 120 days a century later. Summer warming has been shown to increase water stress and reduce tree growth in dry areas of the southern boreal forest in central Alaska, western Canada and portions of far eastern Russia. Precipitation is relatively abundant in Scandinavia, Finland, northwest Russia and eastern Canada, where a longer growth season (i.e. the period when sap flow is not impeded by frozen water) accelerate tree growth. As a consequence of this warming trend, the warmer parts of the boreal forests are susceptible to replacement by grassland, parkland or temperate forest.[55]
In Siberia, the taiga is converting from predominantly needle-shedding larch trees to evergreen conifers in response to a warming climate. This is likely to further accelerate warming, as the evergreen trees will absorb more of the sun's rays. Given the vast size of the area, such a change has the potential to affect areas well outside of the region.[56] In much of the boreal forest in Alaska, the growth of white spruce trees are stunted by unusually warm summers, while trees on some of the coldest fringes of the forest are experiencing faster growth than previously.[57]
Lack of moisture in the warmer summers are also stressing the birch trees of central Alaska.[58]


Ah dear Dohboi, another day, another feedback...

I think we will see all the arctic islands free of sea ice at the end of this month, maybe just the Northern tip of Greenland still attached to what is left of the pack, by then we will be below 2 million sq miles, maybe even getting near that record low of 2012.

Widespread, dangerous heat wave to expand across much of the U.S.

A stifling heat wave has begun to take shape across large portions of the United States, with millions likely to see temperatures creep toward the century mark, along with even higher heat indexes by this weekend.
The heat wave is already generating excessive heat watches in the central United States, and by Wednesday the national weather map is likely to feature a blanket of heat advisories from the National Weather Service. The combination of sultry dew points and scorching air temperatures approaching will help make this event a dangerous one from a public health perspective.

Cities including Chicago, St. Louis, Washington, Philadelphia, New York, Nashville and Kansas City, Mo., are likely to see at least three days with temperatures between 95 degrees and 100 degrees, along with dew points — a measure of the amount of moisture in the air — above 70 degrees.

Here in Poland after very promissing hot June we got rather cold and windy July.
Holidaymakers at the seaside are increasingly unhappy but fortunately I am fully booked up to mid August.
We shall see what will be later.

Israel bakes as temperature climbs to near-record 49.9°C at biblical Sodom



Heat hits 40°C in Tel Aviv, even higher near Dead Sea; heat wave blamed for massive wave of brushfires

A heat wave that struck Israel Wednesday sent temperatures soaring to near-record breaking heights.

The highest temperature in the country was recorded on the southern shores of the Dead Sea, near the site of Biblical Sodom, where the mercury hit 49.9° Celsius (122° Fahrenheit), a record for the spot.

Thanks, OL. 94 F here in Minneapolis, and 65% humidity. I can't imagine it being more humid than this, but that's what more and more of the world will be facing.

How is everyone else who is in this heatwave, covering most of the contiguous US, as I understand it, doing?

I second the motion that it is miserable here in Minneapolis. 111* heat index.

went out to throw a few axes and knives, and it felt like I had been throwing hay bales all day.

94* with dew point of 79*, using the rough wet bulb temp calculation:

(temp-dewpoint)/3, subtracted from the temp = approx wbt of 89. Not nearly 95, but which is already unbearable.
