NASA’s space solar observation platform by observing a few months, to capture the phenomenon of giant convective cells during the slow movement, and its follow-up observations carried out.
The current theory is that the dynamics of the sun, the sun’s thermonuclear fusion occurs when the internal energy source, the energy generated in the internal transport needs to go outside, and then radiated into the surrounding space, the sun’s energy transport from the inside out there convection from these forms to complete.
Scientists now know that the two convective energy forms, namely granulation and supergranulation, by definition granulation is shaped like a grain of rice unstable spots we found when observing the sun on the Earth, is formed on a particle convective cells energy forms like, rice organization has a strict energy upwelling and downwelling, the central region is rising channel flow, down the stream channel around the ring, we can also identify the temperature structure of the energy through color, according to our current granulation understanding of the situation, the size of its individual units is not large, about 1,000 km span, but there are some large scale, can reach more than 30,000 kilometers, there is a longer time, it is also known supergranulation .
In addition to the granulation and supergranulation, the latest discovery is the third type of energy transfer monomer structure, its size is relatively large, but move more slowly, so researchers in identifying these convective cells more difficult, the need for the Solar Dynamics Observatory captured video data every minute observation, so as to find these convective cells.
In the June 8, 2010, scientists discovered the trajectory of a giant convective cells, the underlying monomers are shown in red, announced this discovery allows us to have confirmed the existence of giant solar surface convective cells, it may appear CMEs, and if we uncover the energy exchange with the internal surface of the sun, we can predict the occurrence of events such as flares, such as energy, solar storms before they happen to make a warning, shut down critical equipment in advance of Earth and orbit.
