Historic Arctic cold blast hits Europe: Damaging frost and snow expected across most of continent

extreme cold april europe 2021
An exceptional, more than 100 mbar pressure difference between Greenland and northern Europe on Sunday has released a massive Arctic cold blast towards continental Europe. The sharp Arctic front is racing south and will result in intense snow with blizzard conditions across Slovenia and Croatia on Tuesday. Then, destructive and widespread frost to vulnerable vegetation is expected across central Europe.

A very dramatic weather pattern change is underway this Easter Monday as a deep Arctic cold-core is moving south across western and northern Europe. The first impact is over the UK and Ireland, then the core will spread towards central Europe and the Mediterranean tonight into mid-week days.

100 years later, the Scientific American reversal on CO2

In 1920, Scientific American reported that the atmosphere was deficient in CO2, and that crop productivity could be greatly enhanced by introducing CO2 emissions from from smokestacks, and that earth was covered with luxuriant forests when CO2 levels were much higher.

Fertilizing the air with carbon dioxide to promote plant growth

ONE of the principal constituents making up the body of a plant is carbon, representing about one-half of its organic substance. The opinion that this carbon is derived from the soil has long been abandoned, modern investigation having shown atmospheric carbonic acid to be absorbed by means of the chlorophyll or green matter of the leaves and decomposed into its elements, the carbon, in conjunction with the root sap and atmospheric moisture, being worked into organic compounds.

Whereas atmospheric air at present is relatively poor in carbonic acid, of which it contains only about .03 per cent, at an early period in the development of our planet, when this was covered with the luxuriant forests our coal deposits are derived from, it comprised incomparably greater quantities of this gas. This fact suggested the idea of heightening the fertility of the soil by increasing its carbonic acid content and thus producing conditions resembling those of antediluvian ages.

Unusually deadly avalanche season in Switzerland this winter - 27 killed, 50% above average

Deadly avalanche in Greppon Blanc on 20 March 2021

Deadly avalanche in Greppon Blanc on 20 March 2021
With the end of Switzerland's ski season only weeks away, the number of avalanche deaths this season is already unusually high level.

The average annual number of people caught in avalanches over the last 20 years is 177. This winter 296 people were affected, a 67% rise. 215 (73%) of the avalanches this season were triggered by people, compared to an average of 113 over the last 20 seasons.

Over the same 20-year timespan an average of 18 lives were lost in avalanche accidents per ski season. Up until the end of March 2021, 27 people had died in avalanches this winter season, 50% more than an average season.

Severe frosts damage fruit in Lleida and Huesca, Spain

frost
Last weekend, severe frosts were recorded in the stone fruit producing areas of Lleida and Huesca, in Spain. While temperatures fell below 0ºC during the nights of Friday, Saturday and Sunday, the most severe and longest frost was the one on the night of Saturday. The sector's prospects for the campaign had been great, given the excellent flowering of the fruit trees, but this first adverse weather event in the months prior to the harvest may change everything.

The damage caused by these frosts is severe, according to producers and agricultural organizations, not only because of the flowers that have been lost, but also because of the impact they could have on the quality of the fruit. Although there is still a long way to go before the harvest and more unforeseen weather events could be recorded, the volumes expected after this event could come close to last year's -when they were down by about 30%-, or fall even more.

"Insane depth of cold" to blast Britain in April, as sea ice at both poles continues to grow exponentially

"Insane depth of cold" to blast Britain.

An "insane depth of cold" is set to strike the UK over the Easter weekend, warns the Weather Outlook's Brian Gaze.

Freezing temperatures and frosts will arrive in Scotland on Thursday, April 1, with "polar spring" conditions engulfing the majority of the country by Good Friday.

Looking further ahead, the mercury is expected to sink even lower during the following week, as a violent kink in the jet stream (associated with the historically low solar activity we continue to experience) delivers Arctic air to the lower-latitudes.

Thermometers could sink to -10C (14F) in northern parts, which would topple all-time daily cold records.

The UK's lowest-ever recorded temperature for April 5, for example, is the -9C (15.8F) set in 1990, while 1935's -8.9C (16F) for April 7 could also tumble. In fact, most of the daily benchmarks between early-to-mid April are under threat, including some that have stood for more than a century.

Cascades snow depth running 109% to 167% of normal

Snoqualmie snow
Skiers and snowboarders arrived Monday to fresh snow at Snoqualmie Summit.

"During different times this season it has been the number one snow pack in the county - currently it's over 600 inches (50 feet)at the top of Alpental," said Guy Lawrence, general manager at Summit at Snoqualmie. Fifty feet! That's the height of a 5-story building!

And that will continue growing, because more spring snow is expected.

"Next week we're probably going to get a couple of systems that will bring snow to the higher elevations in the Cascades," said Nick Bond, a professor at the University of Washington and a state climatologist.

Thundersnow at Denver International Airport captured on camera

An unusual thundersnow storm moved directly over Denver International Airport on Tuesday night. Thunderstorm is rare in most of the country but does happen with some regularity in Colorado, mainly in the early spring and late fall.

Thundersnow is simply a thunderstorm that occurs when it is just warm enough for a storm but still cold enough for the storm to produce snow instead instead of rain.

Alex Inscoe captured the weather event on video. It shows lightning during a snowstorm which brought half inch of snow to the airport between 10:15 p.m. and 10:45 p.m.
