Just as a hurricane drives rain, wind, and floods, the space weather arising from a solar eruption can come in different forms. First comes the light from a solar flare, disrupting high-frequency radio communications at the Earth more or less immediately (eight minutes after leaving the Sun).

For the first time a mesoscale-resolving whole atmosphere general circulation model has been developed. This was accomplished using the National Center for Atmospheric Research Whole Atmosphere Community Climate Model with ∼0.25° horizontal resolution and 0.1 scale height vertical resolution above the middle stratosphere (higher resolution below).

NCAR solar physicist Scott McIntosh is raising awareness. While the current peak in the 11-year cycle of sunspot activity is on the weak side, the Sun might still produce a major storm at any point. And as solar researchers point out, the most dangerous storms are most likely during the waning part of the solar cycle, which will unfold later this decade.
