However three days on from the catastrophe, hopes of discovering extra survivors are dwindling.
The courthouse in Valencia metropolis has been transformed right into a morgue, the place well being employees sporting smocks carried stretchers coated with white sheets.
What’s DANA and the way did it trigger Spain’s lethal floods?
The devastating floods have been attributable to a harmful climate system wherein chilly and heat air meet and produce highly effective rain clouds, a sample believed to be rising extra frequent on account of local weather change.
The phenomenon is understood domestically as DANA, a Spanish acronym for high-altitude remoted melancholy, and in contrast to frequent storms or squalls it may possibly kind independently of polar or subtropical jet streams.
When chilly air blows over heat Mediterranean waters it causes hotter air to rise rapidly and kind dense, water-laden clouds that may stay over the identical space for a lot of hours, elevating their harmful potential. The occasion typically provokes giant hail storms and tornadoes as seen this week, meteorologists say.
Which areas are extra vulnerable to DANA?
Japanese and Southern Spain are notably vulnerable to the phenomenon on account of its place between the Atlantic Ocean and the Mediterranean Sea. Heat, humid air plenty and chilly fronts meet in a area the place mountains favour the formation of storm clouds and rainfall.
This week’s DANA was one of many three most intense such storms within the final century within the Valencia area, Ruben del Campo, spokesperson for the nationwide climate company Aemet, mentioned.
“Forecasts have been in keeping with what occurred. However in an space between Utiel and Chiva, within the province of Valencia, rainfall exceeded 300 litres per sq. meter. In that space, storm techniques fashioned and regenerated constantly,” he defined.
The variety of deaths has prompted anger in addition to grief in Spain, with some folks accusing authorities of being poorly ready and never having warned folks quickly sufficient in regards to the risks posed by the storm. Supply: Getty / EPA/Biel Alino
Does local weather change play a component?
Whereas specialists say it should take time to analyse all the information to find out if this explicit DANA was attributable to local weather change, most agree that a rise in temperature of the Mediterranean and hotter and extra humid atmospheric circumstances contribute to producing extra frequent excessive episodes.
“We’ll see extra of those flash floods sooner or later. This has the fingerprints of local weather change on it, these terribly heavy rainfalls, and these devastating floods,” mentioned Hannah Cloke, professor of hydrology on the College of Studying.
She mentioned even early warnings of heavy rain based mostly on dependable forecasts did little to stop the fatalities and other people wanted to grasp the actual hazard.
“Simply telling those who it may rain quite a bit, it isn’t ok…We may see that folks have been placing themselves in danger driving in floodwaters, and there was simply a lot water that it has overwhelmed these locations.”
Earlier than the time period DANA was coined within the early 2000s, any heavy rainfall within the autumn, attribute of the Mediterranean local weather, used to go by the favored title “gota fria” (chilly drop) in Spain and elements of France. The time period continues to be broadly used colloquially.
Its origin dates again to 1886 when German scientists launched the concept of “kaltlufttropfen”, or chilly air drop, to explain excessive altitude disturbance however with out obvious reflection on the floor.
Aemet says the idea of chilly drop is outdated and defines DANA as a closed high-altitude melancholy that has turn out to be remoted and separated from an related jet stream. Aemet says DANAs typically turn out to be stationary and even transfer backwards, from east to west.
