For years, researchers(attempt) to forecast and predict CMEs in hope that warnings could help prevent damage to electronics and the power grid (电网). As it turnsthat a CME is more like a sneeze. Professor Mathew Owens of the University of Reading explains, "The research team and I have found they are more like an(expand) dust cloud or sneeze."
When the solar wind acts on the CME as it moves through space, it causes the shape and behavior of the energy explosion (become) unpredictable. "Therefore if we want to protect (we) from solar eruptions, we need to understand more about the solar wind, "Owens says.
The research team suggests that solar wind readings should (include) in the forecasting and prediction of future CMEs. This study could help scientists more(accurate) assess the risk that the ejections bring to human technology and potentially help reduce the damage they cause.
