Forecasting Space Weather

Caption

Joint research by Southwest Research Institute and NSF-NCAR developed PINNBARDS — a physics-informed neural network that connects surface observations of solar active regions to the deep magnetic dynamics of the Sun. The left figure shows solar observations of two warped toroid patterns (derived from SDO/HMI magnetograms) in the southern and northern hemispheres. PINNBARDS-derived results (center) show magnetic vectors (black arrows) overlaid on bulges (red) and depressions (blue) match with observed toroidal bands. The velocity field is marked with black arrows in the right image. These results provide clues about the global sources of active regions that produce space weather, which can impact our technological society.
