Intense flash floods hit various parts of Europe this week

Severe Weather Europe - 4. August 2018 - 17:59
The jetstream has been fragmented and weak across Europe over the past week or so, lowering the chances of organized thunderstorms. On the other hand, such environments favour slowly moving storm clusters and virtually stationary pulse thunderstorms. Such thunderstorms can produce short and intense rainfall or even prolonged intense rainfall, in case of a slow moving cluster. Flash flooding is a major threat with these thunderstorms. Over the past week, several places in Europe experienced intense flash floods as results of short, but intense rainfall. Arlberg, Tyrol, west Austria Intense flash floods hit Schann, Arlberg, Tyrol in west Austria. Val Ferret, southwest Switzerland Destructive flash flood torrent in Val Ferret, southwest Switzerland on August 1. Žagubici, Serbia Reports indicate well

Hottest day of heat wave ahead: temperatures expected to soar to 47-48 °C in parts of Spain and Portugal – August 4, 2018

Severe Weather Europe - 4. August 2018 - 10:51
Today will be the hottest day of the ongoing heat wave in southwestern Spain and south-central Portugal. Models indicate extremely high peak temperatures, likely close or perhaps even above the current European record. Models agree on peak temperatures reaching 47-48 °C. The hottest areas will be: the entire southern and central Portugal and parts of Andalusia and Extremadura in Spain. Peak temperatures of 47 °C are indicated by ARPEGE model, 48 °C by GFS, while AROME indicates up to 49 °C. In the latter two cases, the European all time maximum temperature record would be broken. It currently seems likely temperatures will peak close to record levels, however, it will take very favourable conditions to surpass the record. All maps:

Max temperatures ever recorded in Portugal

Severe Weather Europe - 3. August 2018 - 16:36
With all the discussions around an extreme heat across Iberian peninsula this week, we take a look at the records of the highest temperatures in Europe. Reaching such high temperatures is a very fine balancing act between numerous factors and there is only a very small window for error if record values are to be reached or not. Max afternoon temperature usually depends on a number factors. They must perfectly align together: apparent temperature in the lowest levels (boundary layer), its relative humidity which is often related to soil moisture and vegetation (evapotranspiration during the day) and winds. Light winds, which can produce Foehn effect can locally enhance temperatures significantly (for example, remember the hot weather in the Norwegian fjords

Three very hot days ahead in Portugal and Spain, Saturday may break European all time record

Severe Weather Europe - 3. August 2018 - 15:10
Parts of Spain and Portugal are gripped in an intense heat wave. Peak temperatures reached nearly 46 °C yesterday. Let us take a look at the expected peak temperatures today and during the weekend. Friday, August 3 In general models agree that today will be warmer than yesterday, by about 1 °C. Expect daytime highs up to 45-46 °C today. Saturday, August 4 Saturday will be the hottest day of this heat wave. Temperatures are expected to peak at 46-47 °C, possibly pushing to 48 °C. If favourable conditions are present, with a good overlap of subsidence and Foehn effect, it is possible a new European temperature record will be reached. Sunday, August 5 On Sunday the heat will abate

Heatwave and climate change having negative impact on our soil say experts

ScienceDaily - 2. August 2018 - 17:23
The recent heatwave and drought could be having a deeper, more negative effect on soil than we first realized say scientists. That's because organisms in soil are highly diverse and are responsible not only for producing the soil we need to grow crops, but also provide humans with many other benefits, such as cleaning water and regulating greenhouse gas emissions.

Arctic cyclone limits the time-scale of precise sea-ice prediction in Northern Sea Route?

ScienceDaily - 1. August 2018 - 16:37
Climate change has accelerated sea-ice retreat in the Arctic Ocean, leading to new opportunities for summer commercial maritime navigation along the Northern Sea Route. International researchers have demonstrated a new system for forecasting sea-ice thickness in early summer in the East Siberian Sea. The system was accurate up to 3 days ahead, representing high potential for use in operational maritime navigation of the Northern Sea Route.

Locally severe thunderstorms across eastern France, northwestern Italy and southern Germany today – August 1, 2018

Severe Weather Europe - 1. August 2018 - 12:40
Quite an interesting afternoon ahead for eastern France, northwest Italy and particularly south to southwestern Germany: expect widespread thunderstorm activity across the region. There is moderate to high instability available with 1000-2000 J/kg MLCAPE, locally up to 3000 J/kg. Deep layer shear is fairly marginal at 20-25 kt supporting the development of multicell clusters. Local interference of winds and relief effects can result in a supercell or two as well. Main threats with these storms will be torrential rainfall and local flooding, severe straight line winds and large hail. If a supercell develops, very large hail is not ruled out. Simulated IR brightness temperature across the region, indicating numerous thunderstorm anvils in the afternoon. AROME model guidance. Map: wxcharts.eu. Moderate

Update on the upcoming extreme heat wave in Spain and Portugal

Severe Weather Europe - 1. August 2018 - 11:52
Pattern evolution and latest model guidance are well on track for the development of an intense heat wave in the second half of this week across Spain and Portugal. We take a look at the latest model guidance. As already evident in GFS model guidance over the past few days, the entire region will experience an intense heat wave, with temperatures pushing into mid to high-40s, quite possibly breaking all-time records. The pattern will be optimal for extreme heat, as mutliple factors combine. GFS even hints at peaks of 50-51 °C, however, this may well be the effect of the relatively low resolution of the model. Models currently agree on the hottest day being on Saturday. It will be very
