Snow Extent in the Northern Hemisphere now Among the Highest in 56 years Increases the Likelihood of Cold Early Winter Forecast both in North America and Europe

Snow extent in the Northern Hemisphere at the end of November represents an important parameter for the early winter forecast. This year snow extent is running much higher than average and according to existing global estimates, it is now beyond the highest ever observed so far. Winter forecast, especially in its early phase and in Europe, might be strongly influenced by such a large snow extent, although many other factors need attention.

SNOW EXTENT IN NOVEMBER 2022..

Northern Hemisphere snow extent is currently indeed very high, now at about 41 million square kilometers..

...

Looking at the below Rutgers Daily Snow Extent map, it is clearly noticeable how Russia is completely covered in snow now. Snow is also seen overwhelming all of Canada, and Alaska, as well as a good portion of the Lower 48. This is an important parameter for the early winter forecast.

You could probably forecast a colder-than-normal winter based on Autumnal Northern Hemisphere snow cover extent alone. It’s the largest snow extent in decades. Having so much snow on the ground means any arctic outbreak is going to be a little bit colder.

...

In North America snow extent for the end of November is more south than normal, especially in the North West and North East sectors of the U.S: Small and scattered negative anomalies are less significant in the picture, mostly affecting central Mongolia, North East China, and the central U.S.

...

According to the Finnish Meteorological Institute, also the total snow mass for the Northern Hemisphere is tracking comfortably above the 1982-2012 average. This result is based on the current Northern Hemisphere snow-water equivalent relative to the long-term mean and variability.

...

Snow extent grew pretty fast in the last 30 days, as it should generally be in this period of course, but 2022 is setting a clearly very favorable season for snow on the ground. In the video below you can see how fast the snow extent increased in the last 4 weeks.

By the way, as a curiosity, the temperature is always colder on the ground in winter and at night in calm conditions, that is without or with the very weak wind. That’s because the Earth warms up and cools off much faster than the atmosphere does. More, colder air is denser, therefore the air near the ground is colder at night than the higher air. That’s why for instance your thermometer says +1 or +2 degrees Celsius, but you might see frost on the ground.

Extensive snow extent early in the season is an indicator of persistent cold as we head into winter proper, mainly due to albedo and emissivity feedback.

Albedo is defined as the fraction of light that is reflected by a body or surface. On average, the Earth reflects about 30 percent of the sun’s radiation, but when fresh snow covers the ground that value nearly triples and it is close to 1.0. In fact, snow has the greatest albedo on Earth, from less than 0.60 for wet and melting snow to greater than 0.85 for fresh snow.

The albedo of fresh snow could be as higher as 0.95, which means it reflects back to space 95 percent of the sun’s radiation, keeping the ground and air much cooler.

It represents an important parameter in climatology since recent albedo decreases in the Arctic have increased heat absorption at the surface leading to the so-called Arctic Amplification. Practically, Arctic lands and sea are warming faster than other environments on Earth due to the positive feedback induced by the darker surface of the land and sea in summer, where there is no snow or ice on the ground or sea ice melted.

A nearly two-decade effort by Californians to cut their emissions of planet-warming carbon dioxide may have been erased by a single, devastating year of wildfires, according to UCLA and University of Chicago researchers.

However, the media will ignore it and the same stupid “Covid compliant” idiots will believe this lie until the day they die. Even if the earth froze over in every location.

A read an article at SciTechDaily last week that said the recent Tonga undersea explosion was the most powerful explosion on Earth since Krakatoa in 1883.

The two unique wobbles in the Earths axis also play a role in surface temperature.

One set of wobbles when Earth is farthest from the sun can cause significant cooling, and a different set of wobbles when Earth is closest to the sun can cause significant warming.

The wobbles, and Earths elliptical path around the sun, mean that the angle of sunlight striking the Earth, and the surface area being illuminated, are constantly changing.

Spiritual forecast:

This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, Traitors, heady, highminded, lovers of pleasures more than lovers of God; Having a form of godliness, but denying the power thereof: from such turn away. (2 Timothy 3:1-5)
Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them. (Romans 1:29-32)
Yet if any man suffer as a Christian, let him not be ashamed; but let him glorify God on this behalf. For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God? And if the righteous scarcely be saved, where shall the ungodly and the sinner appear? Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator. (1 Peter 4:16-19)
Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God. (Acts 14:22)
And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book. And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt. And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever. (Daniel 12:1-3)
And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end. Many shall be purified, and made white, and tried; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand. (Daniel 12:9-10)

And back to the threat of global cooling we go.

I seem to recall, back in the 70s, they WERE worried about another ice age. What idiots.

Thank you for that, Daniel1212.

Those words were excellent encouragement and appropriate admonishment.

We had an explosion of box elder bugs, stinkbugs and ladybugs in the fall over an extended period of indian summer which usually indicates a harsh winter.

Of course it’s due to climate change. That global warming somewhere else is just pushing the cold air to the northern hemisphere…the science is settled (sarcasm)

A colder than normal winter could cause thousands of deaths in Europe and even the northeastern part of the US. Already people in the northeast are having to prioritize between buying food or keeping warm and Biden’s jihad on the US energy sector will just make things worse

Whew! For a minute there I thought the end of snow was here. Guess we have glowbull warming, uh sorry, climate change to thank for that eh? ⛄❄🌬

Partner, these forecasters say it is climate change is why we have so much snow?

We had such a warmer and dry weather summer here in Houston and there were predictions about the cold weather coming this winter.

Exactly! I was thinking the same thing. The pinko-greenies will tell us this is just an example of extreme weather brought about by human caused gloBull warming.

Snow is a good way to alleviate drought. Id rather have cold with snow than dry cold. Snow makes for a nice insulator on the roof and piled up around the foundation. House stays much warmer.

Long term, it waters the ground for deep watering. It refreshes bodies of water...

It’s a pita to deal with but more beneficial than most people realize.
