article_snippet.sent: Researchers have found that twisted bands of magnetic fuel reach the surface of The sun every two years - in addition to The sun existing 11-year cycle.
article_snippet.sent: Every two years it appears 'bands' of magnetic field move to the surface.
article_snippet.sent: a new study found that the changes seem to be driven by bands of strong magnetic fields in The sun's hemispheres which emanate from the solar interior.
article_snippet.sent: this shorter two-year season occurs when twisted, ring-shaped 'bands' of magnetic field rise from the solar interior and pass to the surface through the tachocline - a 'transition' region in the outer third of The sun. '
article_snippet.sent: Much like Earth's jet stream, whose warps and waves have had severe impact on our regional weather patterns in the past couple of winters, the bands on The sun have very slow-moving waves that can expand and warp it too,' said co-author Dr Robert Leamon, a scientist at Montana State University. '
article_snippet.sent: Sometimes this results in magnetic fields leaking from one band to the other. '
article_snippet.sent: In other cases, the warp drags magnetic fields from deep in the solar interior, near the tachocline, and pushes other cases toward the surface.'

article_snippet.sent: The bands   are fueled by the rotation of The sun's deep interior, according to observations by the research team.
