Morphology

magnetic + storm

The meaning 'a sudden disturbance of the Earth's magnetic field' is directly and compositionally derivable from 'magnetic' (relating to the magnetic field) + 'storm' (a sudden violent disturbance). This adjective+noun combination follows a common semantic pattern and has close equivalents in other languages, so a B1 learner who knows both constituents should understand it.

Etymology

The term magnetic storm comes from a simple image: bursts from the sun hit Earth's magnetic field and make it wild like a weather storm, so magnetic points to magnetism and storm shows the sudden, violent activity. So, magnetic storm means a sudden change in Earth's magnetism that can 'disrupt' power systems and satellites.
