A new super Typhoon Trami moving towards Taiwan and Japan this week

Severe Weather Europe - 7 tundi 32 minutit tagasi

A new, very intense super typhoon Trami has developed in the western Pacific this weekend. It has already reached a CAT 4 strength today. Trami packs sustained winds of 140 mph and central pressure of around 938 mbar. The future track of Trami will lead it towards Taiwan and then it will turn north towards a potentially devastating landfall in Japan. Latest infrared satellite imagery reveal an impressive structure of this super typhoon, with tiny pinhole eye surrounded by an compact intense eyewall and a textbook almost undisturbed upper level outflow. Trami will be moving into favorable sea waters for additional strengthening through the next 72 hours, so an intensification into a monster CAT 5 super typhoon is expected later […]

Update on the intense Arctic outbreak next Tuesday

Severe Weather Europe - 20. September 2018 - 23:49

An Arctic outbreak which is expected to shut down late summer across much of Europe, is very well confirmed by the latest model runs. Lets take a look on the latest trends, some minor changes are seen in the pre-outbreak environment. The airmass behind the Arctic front will be extremely cold for late September, such outbreaks are actually quite rare and it could potentially bring first frosty mornings in some regions across east-central Europe and Balkan peninsula by mid next week. The change in pattern starts tomorrow, as the cold front associated with the deep trough/cyclone with windstorm crossing North Sea and Denmark will be pushed across the central Europe and towards the Balkan peninsula. A quite colder airmass will […]

An intense windstorm will hit Denmark tomorrow, Sept 21st

Severe Weather Europe - 20. September 2018 - 16:31

An intense windstorm which is crossing British Isles tonight, will additionally strengthen over the North sea tomorrow morning and head towards Denmark,south Norway and southwest Sweden with extremely severe wind gusts likely. A quite rapidly moving deep cyclone will develop an intense windstorm by midday over the open waters of North Sea and push into Denmark and surroundings through the afternoon hours. A very deep cyclone forms and intensifies while moving across the western Europe towards the southern Scandinavia, in response to a very cold core low associated with a deep long-wave north Atlantic trough, as mentioned in the weekly pattern overview earlier this week. A tight pressure gradient against the ridge to the east will produce very intense wind […]

A medicane expected to fully form east of Sardinia within the next 24 hours

Severe Weather Europe - 20. September 2018 - 12:29

Latest model guidance, together with radar and satellite imagery is now in very good agreement on the developing deep cyclone over the Tyrrhenian sea – a Medicane! Deep convection in ongoing around the centre of the cyclone and tightening pressure gradient is visible. The Medicane is expected to become better organized and more intense within the next 48 hours while it moves along the SE coast of Sardinia towards Tunisia. Today’s morning radar and satellite analysis: notice the pronounced cirrus clouds outflow across the SW quadrant of the cyclone, as well as interesting behaviour of the convective bands around the sistem. 08 UTC or 10am CET pressure analysis across the Mediterranean. The cyclone is centered just east of Sardinia, currently […]

Arctic outbreak will shut down late summer early next week

Severe Weather Europe - 20. September 2018 - 0:41

The weather pattern has become quite dynamic across the western half of Europe lately, between deep Atlantic troughs to the west and persisting ridge to the east. Additionally, a much more significant change in weather is coming soon, as the ridge collapses and a powerful outbreak of Arctic airmass spreads across large part of our continent by early next week. The late summer temperatures we have been enjoying this month will be shut down by two intense cold blasts. The first, weaker cold wave crosses part of Europe this weekend while a more intense Arctic outbreak arrives on Monday and Tuesday and very cold airmass will be advected all the way to the southern Mediterranean and North Africa.

An intense windstorm will cross the British Isles tomorrow night, September 20th, 2018

Severe Weather Europe - 19. September 2018 - 22:06

After windstorm Ali the British Isles are in for another windstorm: yet another deep low passes across the region tomorrow, bringing potentially severe and damaging winds to the region. We take a closer look at the model guidance. A new deep low rapidly develops over the Atlantic ocean just west of the British Isles and Ireland. It moves across Ireland and the UK late on Thursday and early on Friday. High-resolution models agree on the low resulting in a new strong windstorm across parts of the British Isles. We compare ARPEGE and ICON-EU model guidance: both models are in good agreement for peak winds across Wales, northern England and Scotland between late Thursday and early Friday. Indicated peak gusts are […]

Diverse forests are stronger against drought

ScienceDaily - 19. September 2018 - 20:30
Researchers report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual tree species' resilience based on hydraulic traits, lead to new research directions on forest resilience and inform forest managers working to rebuild forests after logging or wildfire.

Update on the developing deep cyclone and Medicane in the Tyrrhenian sea tomorrow

Severe Weather Europe - 19. September 2018 - 16:29

Models are now in good agreement on the development a potentially dangerous weather situation across parts of Tyrrhenian sea and the island of Sardinia. Latest model guidance suggest the today’s convective activity, associated with a weak upper low across the region, will result in rapid cyclonegenesis and the formation of a medicane over the Tyrrhenian tonight, within weak wind shear environment and over a very warm Mediterranean sea. Models are still indicating the likelihood of a warm core system – a medicane (Tropical-like Cyclone) development tomorrow, Thursday Sept 20th. Here is the MNW-WRF model guidance where a large cyclone is indicated over the Tyrrhenian sea. While its wind field is not expected to be particularly severe, gusts up to 80-100 […]
