Despite the fluctuations between years and decades, rainfall in the Mediterranean region have remained stable since the late 19th century, according to a study published in Nature magazine.

Researchers, led by the University of Zaragoza in Spain, received data from 23,000 stations in 27 countries, including Greece, France, Italy, Morocco and Egypt, which analyzed for the period from 1871 by 2020. Their aim was to explore the trends of rainfall in the long run. They also compared the set of data with the modeling from the International Program “CMIP).

Found that rainfall in the area remained in high degree of constantduring this period of time in the last 150 years, although they presented strong spatial volatility and differences between decades ofas well as seasonally. Researchers attribute these differences to atmospheric dynamics. As they note, the data in the present study are in accordance with modeling Cmip 6 For rainfall of the past, both of which do not indicate a prevailing tendency to rain in the past in the area.

They also notice that the atmospheric circulation In the Mediterranean region is characterized by high complexity and further investigation is required to clarify the specific impact of mechanisms associated with the anthropogenic climate change and could lead to reduction of rainfall.

Researchers, however, note that the Mediterranean region is experiencing a period growing climate droughtmainly caused by increased atmospheric exhaust, which is the result of significant observed temperature rise in the area.
