Ich hab gestern aufgeschrieben, welche Rolle der #klimawandel bei den extremen Fluten in Griechenland und #Libyen und die Entwicklung des Sturms zum tropischen Wirbelsturm #Medicane spielte.
TRADUCTION :
« Oui, ces anomalies de température à la surface de la mer (écarts par rapport à la norme) sont encore élevées en Méditerranée (ainsi que dans l’Atlantique et le Pacifique), ce qui ALIMENTE les phénomènes météorologiques EXTRÊMES. »
sur @Infoclimat , un post de Thelj qui effleure la catastrophe en Libye.
Le #medicane#Daniel a déversé de fortes précipitations entrainant une crue et la rupture d'un barrage censé protéger la ville.
#StormDaniel
"As many as 2,000 people may have been drowned after a powerful storm unleashed catastrophic #floods in the eastern Libyan city of #Derna.
The deaths occurred after a powerful storm and heavy floods led to the collapse of two ageing dams, which released a swollen fast-moving river that simply washed away at least one neighbourhood."
"#StormDaniel — dubbed a “#medicane” for its hurricane-like characteristics – drew enormous energy from extremely warm sea water. And a warmer atmosphere holds more water vapor that can fall as rain, experts said."
A look at two of the dams that may have collapsed, leading to the disaster at #Derna from the huge rains of #Medicane#Daniel 🌀. Unrecognized east #Libya 🇱🇾government say deaths exceed 2000.
Images out of #Libya following extreme rainfall from the "#Medicane" (Mediterranean "tropical-like" cyclone) that made landfall this weekend are indicative of quite violent flood inundations. Based on these images, rumors of multiple dam failures unfortunately seem plausible. https://t.co/ZcboOcdzQO
Storm #Daniel is becoming a #Medicane - a tropical-like depression in the Mediterranean Sea. It will quickly move south into Libya, making landfall over #Benghazi tomorrow.
#Medicane
"Ein Medicane (Schachtelwort von englisch Mediterranean hurricane) ist ein tropensturm-ähnliches Sturmtief im Mittelmeerraum. Diese Form des Mittelmeertiefs erscheint vermutlich in einer Häufigkeit von etwa einmal jährlich." (Wikipedia) https://de.wikipedia.org/wiki/Medicane
Development of storm #Daniel that is forecasted to gain tropical characteristics in the coming days and may bring excessive precipitation for parts of #Lybia (weekend+ Monday). Animation shows precipitable water and surface pressure of ECMWF run 06.09. 12 z. #medicane
What's happening in the moment is an OMEGA-Block.
Two low pressure areas over the Mediterranean Sea wedge an area of high pressure over Central and Western Europe. #Medicane#Heatwave#Floods#StormDaniel in #Greece and Spain.
Fire to #flood: Greece's destructive roller-coaster ride
A summer in #Greece marked by deadly convulsions of #wildfire has plunged into an intensely wet week that has already dumped more than 20 inches (500 millimeters) of rain on parts of central Greece. The rains are being driven by an upper-level low pressure system, dubbed #Daniel, that may transition into a #medicane, or #Mediterranean tropical-like cyclone.
Omega block over Europe - high pressure heat dome flanked by low pressure systems.
Extreme heat for France , UK and others.
Medicane (Mediterranean Hurricane) brewing in the Mediterranean.
Catastrophic rainfall in Greece - up to 1 meter over the next few days.
DANA in Spain.
Hurricane Franklin may re-group and strike the Iberian Peninsula.
It's autumn.
Yup, those Sea Surface Temperature Anomalies (deviations from norm) are still high in the Mediterranean (and in the Atlantic and the Pacific), providing fuel for extreme weather.
