New analysis questions prior assumptions
A recently released investigation appearing in the scientific periodical Nature indicates that the consequences of severe space weather episodes might be more substantial than earlier evaluations supposed. The paper is named "Regression to the mean can explain saturation of geomagnetic storms" and was directed by Dr. Nithin Sivadas of NASA's Goddard Space Flight Center.
Dr. Maria Walach from Lancaster University took part in the work as a co-author. The findings imply that statistical phenomena such as regression to the mean can affect comprehension of how geomagnetic storms saturate, potentially skewing existing risk estimates.
Relevance for hazard evaluation
Geomagnetic storms originate from solar activity and can disrupt satellites, power grids and communication networks on Earth. Should their real threat level exceed current models, operators of essential infrastructure may have prepared insufficient safeguards.

- Focus on saturation of geomagnetic storms
The team stresses that their examination is intended to refine the basis of space weather forecasting. Additional research will be required to define the practical implications for protecting technical assets with accuracy.
