An Arctic outbreak likely to blast into western Europe next weekend (end of March) https://www.severe-weather.eu/mcd/arctic-outbreak-western-europe-next-weekend-mk/ Mon, 23 Mar 2020 19:37:37 +0000 https://www.severe-weather.eu/?p=168684

We are just seeing a pretty strong outbreak of cold air mass into east-central Europe this week, there is more coming soon! It appears likely another *very* powerful ridge/high-pressure system will form over North Atlantic and introduce a significant cold outbreak into western and potentially also southwestern Europe through the final days of March. Even […]

Winter is back to the Balkans – a huge amount of snow is expected in some areas until Thursday, hurricane-force Bora along the Adriatic coast https://www.severe-weather.eu/mcd/winter-balkans-huge-amount-snow-mk/ Mon, 23 Mar 2020 10:45:11 +0000 https://www.severe-weather.eu/?p=168612

A strong cold outbreak is underway across the east-central Europe and the Balkans this week, in response to a very powerful upper ridge and 1040+ mbar high-pressure system over northern half of Europe. The pattern also introduces a snowfall event over the Balkans where a deep upper low will maintain over the western part of […]

Spectacular mesovortices within the core of monster North Atlantic cyclone – the system has matured today and is now moving into Iceland https://www.severe-weather.eu/mcd/spectacular-mesovortices-core-north-atlantic-cyclone-mk/ Sun, 22 Mar 2020 23:21:13 +0000 https://www.severe-weather.eu/?p=168629

A very large North Atlantic depression has peaked today. It reached 953 mbar with the rapid intensification completed on Sunday morning. It, yet again, delivered a spectacular satellite presentation of the cyclone’s core, also with very interesting features in the evening hours – several mesovortices within its large core. The system is now moving across […]

A widespread cold air mass advection is underway towards central Europe – cold outbreak intensifying tomorrow while spreading into the Mediterranean https://www.severe-weather.eu/mcd/widespread-cold-advection-underway-central-europe-mk/ Sun, 22 Mar 2020 19:13:11 +0000 https://www.severe-weather.eu/?p=168584

A powerful high-pressure system is dominating much of Europe today, centered over the Baltic region. With northeasterly winds along the southeastern flank of the ridge, a much colder air mass is now underway across the Balkans and central Europe. A developing cold outbreak intensifies tonight as the upper low aloft deepens. The much colder air […]

*COVID-19 vs Climate* Global CO2 levels have temporarily stopped rising, likely due to the industry slowdown as the world battles the new Coronavirus https://www.severe-weather.eu/global-weather/covid-19-global-co2-slowdown-climate-fa/ Sun, 22 Mar 2020 16:30:32 +0000 https://www.severe-weather.eu/?p=168522

As the world continues the fight against the COVID-19 pandemic, we are starting to observe first potential effects on the climate system. The CO2 levels have currently paused the seasonal increase, likely due to the slowdown of the industry in China and the rest of the countries that are dealing with the outbreak of the […]

A rapidly intensifying extratropical cyclone in the North Atlantic this weekend – broad severe winds towards WNW Europe https://www.severe-weather.eu/mcd/rapidly-intensifying-cyclone-north-atlantic-mk/ Sat, 21 Mar 2020 21:10:00 +0000 https://www.severe-weather.eu/?p=168494

It’s been about a week since the last deep cyclone over the North Atlantic, as strong ridge developed over the last days. To the west of the ridge, a very powerful frontal system and deep extratropical cyclone have developed today, over the Northwest Atlantic and the southern Labrador Sea. Rapid intensification is now underway, developing […]

New data of #COVID-19 effects on the significant decline of nitrogen dioxide over China, now again increasing as lockdown is over https://www.severe-weather.eu/global-weather/nitrogen-dioxide-emissions-china-mk/ Sat, 21 Mar 2020 12:47:17 +0000 https://www.severe-weather.eu/?p=168461

The new data analysis by the Copernicus Sentinel-5P satellite reveals significant changes in the air pollution across China. Data analysis between late December and mid-March shows a significant decline in nitrogen dioxide (NO2) emissions during China’s national lockdown in January and February, followed by an increase of air pollution once the national lockdown is canceled […]

Cold outbreak with the significant temperature drop in the next days – *HIGH risk* for damaging frost of fruit trees across west-central Europe, Italy and the Balkans https://www.severe-weather.eu/mcd/significant-temperature-drop-high-risk-damaging-frost-mk/ Fri, 20 Mar 2020 19:05:55 +0000 https://www.severe-weather.eu/?p=168449

All models are in very good agreement we will be facing a powerful and very dangerous cold outbreak from Sunday through Thursday. An advection of extremely cold late March temperatures will spread across east-central Europe and the Balkans first, then also reaching the Mediterranean and western and southwestern Europe. There is a *high risk* for […]

Exceptional but very didactic NASA Terra-MODIS satellite imagery of the Arctic region https://www.severe-weather.eu/recent-events/exceptional-didactic-satellite-imagery-arctic-region-mk/ Thu, 19 Mar 2020 11:50:01 +0000 https://www.severe-weather.eu/?p=168396

Daylight is slowly expanding towards the Polar region as we’re going further into spring. This means we can observe some pretty spectacular imagery on the Arctic region sea ice extent we couldn’t see weeks ago during the polar night. Over the last few weeks, some clear days finally opened the skies so we can see […]

Arctic cold outbreak develops across the United States tonight and continues into the weekend https://www.severe-weather.eu/global-weather/arctic-outbreak-united-states-mk/ Thu, 19 Mar 2020 09:43:49 +0000 https://www.severe-weather.eu/?p=168410

Both European and American continents are ahead of a significant pattern change this week. Similar to Europe, an Arctic outbreak is expected to spread across a large part of the United States after today, with an extensive high-pressure system expanding from Canada. Temperatures will fall below 20 °F across the northern half of the US, […]

Rex block pattern develops a dangerous Arctic outbreak across east-central Europe after Sunday – much colder weather is expected https://www.severe-weather.eu/mcd/dangerous-arctic-outbreak-east-central-europe-worsening-covid19-outbreak-mk/ Tue, 17 Mar 2020 21:09:41 +0000 https://www.severe-weather.eu/?p=168335

A large part of Europe is facing a very warm period this week, as a strong Omega blocking pattern has established. But a significant pattern change is coming up this weekend, NAO (Noth Atlantic Oscillation) turns into a negative phase. This means a strong upper-level ridge will develop over the Atlantic and expanding into Europe […]

*Rare event* A rare Ozone hole develops over the Arctic/Canadian region, unusually strong for the Northern Hemisphere! https://www.severe-weather.eu/global-weather/rare-ozone-hole-arctic-polar-vortex-fa/ Mon, 16 Mar 2020 22:42:37 +0000 https://www.severe-weather.eu/?p=168217

It is a rather rare occurrence to see a larger area of sustained ozone depletion over the Arctic regions during the late winter/early spring season. But this year, records were broken, as an unusually large area of ozone depletion has formed. We have all heard of ozone before. More likely in the context of the […]

A very warm period across a large part of Europe this week, locally more than 20°C again. But much colder across the UK, Ireland, and Turkey https://www.severe-weather.eu/mcd/very-warm-period-large-part-of-europe-cold-uk-mk/ Mon, 16 Mar 2020 22:06:42 +0000 https://www.severe-weather.eu/?p=168282

An extensive upper-level Omega blocking pattern is establishing across a large part of Europe this week. It will bring spring-like weather across the east and central Europe, partly also over southern Europe. Afternoon temperatures will locally exceed 20 °C. Cold weather develops over UK and Ireland, persisting over Turkey as well. An Omega blocking pattern […]
