The ” Ianos “, the Mediterranean Cyclone (Medicane) that struck Greece in September 2020, was the strongest recorded in the Mediterranean since the mid-20th century.
This is the conclusion of a new study by the scientific team of the National Observatory of Athens / meteo.gr, which was published in the journal of the American Meteorological Society “Bulletin of the American Meteorological Society (BAMS)”, based on terrestrial and satellite observations.
Ianus began to grow on September 15, 2020 in the Gulf of Sirte in Libya and, after traveling about 1,900 kilometers passing over the Ionian Islands on 17-18 / 9/2020, arrived weakened off the coast of Egypt on 21/9/2020. In collaboration with the Ionian University, which operates a local network of meteorological stations in areas hit by Ianos in the Ionian Islands, wind speed data were analyzed with maximum values at 159 km / h and gusts at 195 km / h in Kefalonia in the early hours of Friday 18 September. 2020.
Impressive were the daily rainfall in Kefalonia, which reached 644.7 mm in less than 24 hours (769 mm in 48 hours) and resulted in severe landslides and torrents on the island. However, the floods in Thessaly were also catastrophic, where the network of meteorological stations of the National Observatory of Athens / meteo.gr recorded a maximum rainfall of 317 mm in Pertouli.
In addition, the study analyzes for the first time the vertical structure of the clouds of Ianos, using data from the satellite GPM Core Observatory, which has recorded the center of a medicane only once more, in the case of “Zeno” in November 2017.
