An intense extra-tropical cyclone (bombogenesis) will move across the north Atlantic tomorrow, nearing Iceland/Greenland on Thursday, Feb 19-21st

Severe Weather Europe - 19. Veebruar 2019 - 12:00

A very intense cyclone (a so-called ‘bombogenesis’ cyclone or a weather bomb) will develop across the North Atlantic later today and move towards Iceland and Greenland tomorrow and on Thursday. A violent windstorm will result from this cyclone, bringing extremely severe winds in excess of 150 km/h as well as significant wave heights up to 15 metres. The system develops over the northwest Atlantic today as a sharp wave ejects off Nova Scotia (Canada) and a trough rapidly deepens over the warmer waters of Atlantic ocean. A very intense surface cyclone will be associated with this deepening trough, resulting in a very intense wind field in the lowest levels. Attached is the sequence of cyclone development across the North Atlantic. […]

SWE Photography Contest Summer Challenge 2019 No.1: Lightning

Severe Weather Europe - 18. Veebruar 2019 - 19:42

Get ready to shoot it out with you fellow photographers – here is a photography challenge that will test you and push your photography prowess to the limit. From capturing rare bolts from the blue, to the elusive tendrils of upward streamers to ghostly upper atmosphere lightning. Capture the following lightning phenomena and enter them into the SWE Photography contest: 1. “Bolt from the blue”: capture a bolt from the blue – lightning bolt striking from the updraft or anvil region of the thunderstorm clear of the rain-free base or precipitation of the storm (e.g. away from the thunderstorm). bolt from the blue over the Adriatic sea: lightning bolt emerges from high in the updraft and strikes outside the main […]

Weekly pattern overview across Europe – stable and unusually warm weather will continue for another week, Feb 18-25th

Severe Weather Europe - 17. Veebruar 2019 - 22:53

Europe has been dominated by a strong ridge through mid February and model trends are suggesting yet another week of stable and unusually very warm weather across a large part of our continent. Monday, Feb 18th An upper ridge dominates the eastern half of Europe, including parts of north Europe, central Europe and the Mediterranean. A short wave trough moves across the UK with a surface cyclone centered over the northeast Atlantic, just east of Iceland. Very warm airmass will be placed across central Europe, Baltic region and southern Scandinavia. Tuesday, Feb 19th The upper ridge starts diminishing and moves into the ESE Europe as a trough/cyclone from the NE Atlantic pushes into northern Europe. Very warm airmass spreads into […]

Very warm weather across much of Europe to continue for the next several days

Severe Weather Europe - 14. Veebruar 2019 - 15:43

As the powerful ridge over Europe strengthens, we are looking at another 3-4 days of very warm weather for February across most of the continent. Much of Europe is under a broad ridge, centered over Germany today, with surface pressure reaching close to 1040 mbar. The ridge will slowly move southeastward over the next few days, but high temperatures will persist at least until Sunday when a shallow trough pushes in from the west for a brief respite. Outlook by day. Maps: GFS 850 mbar temperature anomaly map, GFS 2 m temperature anomaly map, ECMWF 850 mbar temperature anomaly map Friday, February 15th Saturday, February 16th Sunday, February 17th More on the pattern across the continent this week: Weekly pattern […]

Storm photography standard zoom lens considerations and recommendations for crop sensor DSLRs

Severe Weather Europe - 10. Veebruar 2019 - 19:40

As the new storm season approaches many of you will be looking to upgrade your lens lineup. Many may also be looking at spring sales of cameras, to get a new one and shoot some storms. We go through the requirements storm photography puts on cameras and standard zoom lenses, and our experience with fast standard zoom lenses for crop sensor DSLRs with some lens recommendations. Photographing storms puts a wide range of requirements on lenses. Photographing in broad daylight and photographing lightning at night, the lens must be sharp. But photographing in low-light conditions, either at dusk and night or in darkness due to thunderstorms, the lens must be able to gather as much light as possible. As if […]

Deep cyclone and a potentially powerful windstorm for parts of the British Isles and Ireland on Friday and Saturday

Severe Weather Europe - 7. Veebruar 2019 - 17:20

A very deep cyclone will affect the British Isles and Ireland on Friday and Saturday. It will produce storm to potentially hurricane force winds, and locally quite significant rainfall totals. This is a potentially dangerous system for places along the track of maximum winds. The cyclone formed off the coast of Newfoundland late on Wednesday, moving east-northeast and rapidly deepening to 988 mbar by early Thursday afternoon. The cyclone will track ENE towards the British Isles and Ireland, rapidly deepening The system will produce a wide swath of severe to locally extremely severe winds. Winds gusting above 100 km/h are expected across much of Ireland, Scotland, southwest and north England and Wales. Maximum wind gusts across the British Isles and […]

Melting ice sheets may cause 'climate chaos' according to new modelling

ScienceDaily - 6. Veebruar 2019 - 20:19
The weather these days is wild and will be wilder still within a century -- in part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around the globe. A new study is the first to simulate the effects, under current climate policies, that the two melting ice sheets will have on ocean temperatures and circulation patterns as well as on air temperatures by the year 2100.
