Update on the Arctic airmass outbreak across Europe this weekend

Severe Weather Europe - 16. Märts 2018 - 18:00
Latest updates on the beginning Arctic outbreak this weekend: very cold airmass is already pushing south and west from Scandinavia and extreme NE Europe into northern parts of central Europe. Latest updates on the beginning Arctic outbreak this weekend: very cold airmass is already pushing south and west from Scandinavia and extreme NE Europe into northern parts of central Europe. Latest GFS model guidance for Saturday, March 17th indicates the belt of cold airmass, with temperatures more than 10 °C lower than average for this time, stretching across most of northern parts of eastern Europe across central into western Europe, pushing over the British Isles. By mid-Sunday, March 18th the cold airmass pushes south into central and eastern Europe (as

Updates on the upcoming Arctic outbreak this weekend

Severe Weather Europe - 14. Märts 2018 - 12:17
Latest updates on the upcoming significant Arctic outbreak this weekend; various models are in a good agreement on the widespread cold airmass advection later this week, starting on late Friday across NE Europe and spreading further WSW over the weekend. Below is the GFS model map for Saturday afternoon, March 17th, when the cold airmass will already be spreading across parts of central Europe, reaching Germany and northern Alpine region in the afternoon hours. Notice the strong warm advection across the Balkan peninsula ahead of an associated deep trough / cyclone located over the northern Mediterranean at that time. This cyclone will bring excessive rainfall into N Italy and NW Balkan countries on Fri/Sat timefram,e before precipitation turn into snow

Damaging tornado in Caserta, southern Italy last night – March 12, 2018

Severe Weather Europe - 13. Märts 2018 - 19:38
A damaging tornado hit the vicinity of Caserta in Campania, southern Italy last night. Significant damage has been reported, as well as at least 15 injuries. Affected areas include San Nicola la Strada, Marcianise, Capodrise, Recale, Portico and Macerata. Reported damage includes damaged roofs on buildings, uprooted trees and overturned cars and larger vehicles. While it is still early in the season, Italy is no stranger to tornadoes. In the past several years it has experienced wedge tornadoes and tornadoes as strong as F4. Italy may also hold the record for the strongest tornado in Europe.

Another cold outbreak across Europe next week

Severe Weather Europe - 13. Märts 2018 - 11:38
Latest runs of global models are confirming the arrival of winter weather and the cold outbreak across much of Europe next week, a complete pattern flip is more or less confirmed. Very cold daily temperatures and locally snow are expected as well. The pattern change will establish a blocking ridge across the Arctic region which then gradually expands onto N Atlantic and establishes meridional flow from the NNE parts of our continent towards south. An intense cold advection will push south towards central Europe and Mediterranean, starting Saturday, March 17th and continue into next week. Temmperatures are likely to be even 10°C or more colder than the long term average for mid March locally, even with near or below freezing

No laughing matter, yet humor inspires climate change activism

ScienceDaily - 1. Märts 2018 - 22:15
Melting icecaps, mass flooding, megadroughts and erratic weather are no laughing matter. However, a new study shows that humor can be an effective means to inspire young people to pursue climate change activism. At the same time, fear proves to be an equally effective motivator and has the added advantage of increasing people's awareness of climate change's risks.
