Cold wave reveals potential benefits of urban heat islands

ScienceDaily - 23. Juuli 2018 - 21:30
Researchers have found that the urban heat island effect -- cities are hotter in the summer than their surrounding areas -- also helps keep cities warmer during extreme cold. The findings have implications for urban planners in areas such as New York City or Chicago, which experience marked seasonal temperature swings.

Big hailstorm dumps a blanket of hail up to 20 cm thick – France, July 20, 2018

Severe Weather Europe - 23. Juuli 2018 - 2:44
An intense hailstorm hit Morez, Haut-Jura, France on Friday, during the expected severe thunderstorm day across the broader Alpine region, dumping a thick hail of blanket, up to 20 cm thick in some places. Snow ploughs were used to clear roads and parking lots. This was a remarkable event. While hailstone size remained moderate, the hail blanket thickness was exceptional. What is particularly noteworthy is that this was a blanket of hail, not local accumulations made by storm runoff carrying hailstones. The hail blanket was locally up to 20 cm thick!

Wave energy converters are not geared towards the increase in energy over the last century

ScienceDaily - 20. Juuli 2018 - 18:28
Wave energy converters are designed to generate the maximum energy possible in their location and take a typical year in the location as a reference. Researchers have been exploring how ocean energy in Ireland has evolved during the last century. The results reveal an increase of up to 40%, which directly affects the output of the converters.

Severe weather outbreak across the Alpine region possible, July 20th

Severe Weather Europe - 20. Juuli 2018 - 10:51
A significant outbreak of severe thunderstorms is possible today over a broad zone stretching from eastern and southern France across the Alpine region, plains of north Italy into Slovenia. Today’s weather pattern across Europe reveals one large upper ridge positioned across Scandinavia and NW Russia and another one stretching from northern Africa into southern Mediterranean. A large pool of low geopotentials is gradually weakening across SE Europe. To the west, a trough is deepening across SW Europe and slowly progressing towards the Alpine region. Rather strong warm advection beneath a southwesterly jet stream is resulting in moisture recovery across the northern Mediterranean region and favors a possible outbreak of severe thunderstorms later this afternoon and evening hours.

In a warming climate, Arctic geese are rushing north

ScienceDaily - 19. Juuli 2018 - 21:21
As Arctic temperatures continue to rise, migratory barnacle geese have responded by speeding up their 3,000-kilometer migration in order to reach their destination more quickly with fewer stops along the way, according to new evidence. Unfortunately, the birds' earlier arrival isn't making as much of a difference as one might expect.

Extreme heat wave causes numerous wildfires in Sweden – July 19, 2019

Severe Weather Europe - 19. Juuli 2018 - 10:51
Northern Europe has been in an extreme heat wave for weeks now. Temperatures are regularly exceeding 30 °C across large parts of the region and rainfall has been exceedingly low. The dry vegetation is providing perfect fuel for wildfires. Ongoing wildfires, July 19, 9:00 am local time. Map: sosalarm.se As of this morning 35 significant fires were being tracked in Sweden. The hot weather is expected to continue, with the possibility of even more intense heat next week. Forest fire in Jämtland, Sweden late on July 18. Photo: Fältjägarbataljon FB.

Huge waterspout buzzes boat in southern Italy – July 17, 2018

Severe Weather Europe - 18. Juuli 2018 - 22:15
In a move which series “Storm Chasers” fans will find more reminiscent of the TIV and the Dominator, a boat made a near-intercept of a large waterspout. The massive waterspout formed off the coast of Minori, Salerno (Campania), southwestern Italy in the morning of July 17. The waterspout grazed a boat, passing it within meters. We would definitely love to see the footage from the boat! Definitely a view worthy of “Storm Chasers”! Below is another view, from a somewhat larger distance – certainly a beautiful waterspout!

Lots of lightning activity through the first half of this week

Severe Weather Europe - 18. Juuli 2018 - 16:25
Weather pattern across Europe has been supporting quite a dynamic period this week. A strong ridge across NNE Europe was holding stable conditions there, while one large upper low over E Europe and deep trough from SW Europe across N-CNTRL Mediterranean brought a lot of severe weather. Indeed also a lot of lightning activity. This 48-hour map reveals where the prime conditions for storms were – more than 512.000 lightning strikes were detected! The most robust storms were across the north-central Mediterranean as a cold front was pushed through the region, resulting in wideapread severe weather with damaging supercells and large storms clusters. Many regions in S France, N Italy and along the Adriatic sea were reporting severe weather, including

Europe’s pattern overview for the next 7 days (July 18-25)

Severe Weather Europe - 18. Juuli 2018 - 16:04
Here is a followup on the pattern evolution this week. A strong upper ridge remains in place across N-NE Europe and NW Russia, resulting in abnormally high temperatures over the region. Locally up to +34 °C daytime peak temperatures are observed – many stations have broken all time record values! A subtropical ridge remains in place also across N Africa and S Mediterranean (Algeria continues experiencing daily maximum temperatures up to nearly +50 °C). A large upper low with lots of convective activity is placed across SE Europe. A developing trough over the E Iberian peninsula can be seen as well; it is expected to deepen while it moves east across Iberia towards N Mediterranean later this week. The improved
