A recent study has revealed a correlation between solar cycles and drought patterns in Europe, particularly in Germany. The research focused on the Hale cycle, a roughly 22-year solar cycle, and its impact on precipitation.
The Standardized Precipitation Evapotranspiration Index (SPEI) was used to assess drought conditions. Analysis showed that drought intensity in Germany and parts of Europe fluctuates with the Hale cycle.
Years with low solar activity, especially in cycle year 9, exhibited increased drought intensity. This was observed in several European capitals, including Berlin, Paris, and Madrid.
Projections suggest an elevated risk of extreme droughts between 2027 and 2029. During this period, the Hale cycle will be in its drought-prone years 17 to 19.
The study highlights the importance of considering solar influence in climate research. It underscores the need for improved climate models and proactive measures to protect ecosystems and agriculture.
