Very warm Mediterranean sea – and what that means for severe weather in the autumn

Severe Weather Europe - 3. August 2017 - 17:22
We take a short look at the weather patterns across the Mediterranean in the autumn that produce severe weather and how high sea surface temperatures may affect them. There are several weather patterns that generate particularly severe thunderstorms across the Mediterranean, particularly the N-CNTRL part. As summer progresses into autumn increasingly deep troughs enter the Mediterranean region, producing severe weather setups. Major flooding – particularly along the Ligurian coast (NW Italy) and north Adriatic region (NE Italy, W Slovenia, NW Croatia) Increasingly deep troughs over the northern Mediterranean with secondary cyclogenesis frequently establish slow moving strong surface wind convergences over the Ligurian sea. Lifting along the convergence and strong jetstream aloft produce long convective lines of training thunderstorms, that produce

Defunct satellites: Reliably determine and predict attitude motion

ScienceDaily - 2. August 2017 - 15:33
Uncontrollable flying objects in the Earth‘s orbit are an enormous risk for active satellites and for spacecraft in general. Since April 2012, the European environmental satellite ENVISAT has also been adrift in orbit. Now, experts have developed pioneering methods to precisely determine the attitude rotation of malfunctioning satellites and, thus, to support de-orbiting missions in the future.

Heat wave health risks

Severe Weather Europe - 2. August 2017 - 14:13
The ongoing heat wave across southern and southeastern Europe is pushing temperatures in the high 30s and locally even well above 40 °C – an extended period of such hot weather is physically challenging and presents an enhanced risk for health. Very hot weather, in particular in extended periods – heat waves – is uncomfortable, but it also presents a very significant health risk. During the European heat wave of 2003, the most intense heat wave in Europe on record, over 70 000 people died as the result of the hot weather. As the heat wave in southern and southeastern Europe intensifies, make sure to know the health risks and how to keep you and your loved ones healthy. Here

Successful prediction of multi-year US droughts and wildfire risk

ScienceDaily - 1. August 2017 - 16:45
A new study shows that difference in water temperature between the Pacific and the Atlantic oceans together with global warming impact the risk of drought and wildfire in southwestern North America. A new model proves capable of much longer-term forecasts of mega-drought and active wildfire seasons than those currently available to people in agriculture, water management and forestry.

Spectacular mud flow captured in Pians, Tyrol, Austria – July 30, 2017

Severe Weather Europe - 31. Juuli 2017 - 11:42
A spectacular, textbook mud flow was captured on cameras in Pians, Tyrol, W Austria yesterday afternoon, July 30. A mud flow is a form of mass wasting and slope mass movement, similar to landslides and debris flows. It is a fast, rapidly surging flow, much faster than a landslide and more fluid than a debris flows. Mud flows usually originate from landslides, which become saturated with water and mobilize into a rapidly moving flow. The Pians mudflow caused little damage, except for filling the channel and spilling over bridges, requiring cleaning, but mudflows (and similar debris flows) can be deadly and there have been numerous occasions across the Alps of devastating such events.
