Devastating DANA Brings Deadly Flash Floods to Spain

Spain faces catastrophic flash floods and extreme weather due to DANA, a high-altitude isolated depression. Experts link the growing frequency of DANA to climate change. Distinct from regular storms, DANA produces heavy rain, hail, and tornadoes by forming dense clouds when cold air meets warm Mediterranean waters.

On October 30, catastrophic flash floods have left at least 72 people dead in Spain, primarily caused by DANA, a high-altitude isolated depression. Experts indicate that this weather phenomenon, distinct from ordinary storms, is becoming more frequent due to climate change.

DANA is generated when cold air encounters warm Mediterranean waters, creating dense, water-rich clouds that can persist in one area for prolonged periods. This leads to increased rainfall, large hailstones, and even tornadoes. Particularly affected are the eastern and southern areas of Spain due to their geographical location between the Atlantic Ocean and the Mediterranean Sea.

According to Ruben del Campo from the national weather agency Aemet, this week's DANA ranks among the three most intense storms in the Valencia region over the past century, with certain areas experiencing rainfall exceeding 300 litres per square meter. While further data analysis is required to conclusively link this event to climate change, the consensus remains that such extreme weather events will become more frequent and intense.
