The flood disaster in the Krasnodar region was a natural disaster that began on July 6, 2012, when prolonged, extremely heavy rain began to fall in the southern Russian region of Krasnodar on the north-eastern Black Sea coast . This rainfall caused flash floods , landslides and floods that killed at least 170 people and injured 300 others. The focus of the disaster was in Krymsk and the surrounding area. In Rajon Krymsk were more secure than 150 corpses after the city and its surrounding area was flooded by an eyewitness reports seven meter high tidal wave.

Thunderstorms of a cyclone reaching up to 12 km high slowly moved from the eastern part of the Black Sea over the west of southern Russia and remained almost stationary there, which is why there were long periods of heavy rain in southern Russia. The height of the system played just as much a role for the thermal and dynamic processes as the mountainous landscape. Due to the unstable atmospheric situation, persistent rainfall began in the region from July 4th. Up to 126mm of rain fell in the region by July 5th. There was a risk of tornadoes above the water . The heavy rain continued on July 6th. According to the state meteorological service, 280 mm of precipitation fell in Gelendzhik within just a few hours , which corresponds to the average rainfall of four to five months. The rain lasted all night.

Other areas in southern Russia and in the northern Caucasus also recorded high levels of precipitation on the night of July 6th. In Volgograd there was 43 mm of precipitation, and the wind speed reached 100 km / h in gusts. The region around Rostov-on-Don received up to 23 mm of rain, Adygea 33 mm, in Dagestan 31 mm of precipitation and hail with a grain size of up to 27 mm fell in less than an hour .

At the same time, there were severe monsoon floods in eastern India on the Brahmaputra , while in north-eastern central Russia, after a long drought, numerous forest fires broke out by mid-June. In southern Europe, too, there was an abnormally unstable weather phase, with extreme heat, severe thunderstorms and storms. This is a - after the Europe-Central Asia-cold wave in January / February - more extreme effects of the Arctic Oscillation , probably in connection with the folding La Niña -to- El Niño is seen.

Model study on the effects of ocean warming

A study from 2015 came to the conclusion that similar extreme weather events will occur more frequently around the world due to the rise in sea temperature. The simulations of the weather at Krymsk showed in a model way how catastrophic effects result from exceeding a threshold value. This phenomenon, known as the tipping point , led to significantly more humid air in the upper atmosphere near Krymsk and, as a result, to exceptionally heavy local rainfall. The authors state: "Over the entire eastern Mediterranean and Black Sea, the atmosphere has become significantly more unstable due to ocean warming" .

tidal wave

Krymsk region - Novorossiysk - Gelendzhik ; marked: area with reported flood victims

On Saturday, July 7th, around 2:00 a.m. local time (10:00 p.m. UTC on July 6th), a tidal wave struck the city of Krymsk, on the banks of the Adagum River . Houses were flooded right up to the roof ridge and numerous residents escaped to the roofs.

Thousands of houses were flooded, around a hundred of which were destroyed by the flood. 2,800 people were brought to safety. 13,000 residents of the region were directly affected by the flood. The highway A146 from Krasnodar to Novorossiysk was interrupted. In Gelendzhik, at least five people died from electric shock as a result of the flood .

Angry residents accused the authorities of failing to warn in good time and of hiding the truth about the causes. Russian Minister for Civil Protection Vladimir Putschkov admitted that officials from the local authorities made mistakes. The local leader of the opposition party Yabloko , Sergei Mitrokhin, accused the authorities of Twitter, the spillway , the contactors to open the DHW storage Neberdschajewskoje, thus causing the tidal wave. These allegations were rejected by the regional government as "total nonsense", reported RIA Novosti . The drinking water reservoir is located on the Neberdschai , which flows into the Adagum and, like other rivers in this catchment area , swelled strongly.

The loading of oil in the port of Novorossiysk has ceased.

Reactions

More than 1000 helpers were flown in to save the affected population and to help with clean-up work. Russian President Vladimir Putin traveled to the affected region to assess the situation and ordered an investigation. The judiciary is investigating an unknown person for negligent homicide . National mourning was ordered for one day across the country.

Meredith, Edmund ( Helmholtz Center for Ocean Research ) et al. in Nature Geoscience : Crucial role of Black Sea warming in amplifying the 2012 Krymsk precipitation extreme Our results reveal a physical mechanism linking a sudden amplificat ion of coastal convective precipitation extremes to gradual SST increase. The increased lower tropospheric humidity provides a richer moisture source for convective precipitation and contributes to low-level instability. More importantly, the near-surface warming reduces static stability, allowing deep convection to be more easily triggered. published July 13, 2015
