In fact, it's often claimed that, when the seeing is less than ideal, smaller apertures are affected by fewer convection cells
(or perhaps only one) and thus can provide a more stable image compared to that from a larger instrument.
The sun is covered with granular convection cells
similar to a pot of water at a rolling boil.
The 'X' feature is likely one of these - a former quadruple junction where four convection cells
meet," NASA said.
4) Analyzing the flow structure, we found these humps to be a result of short-range convection cells
Once at the surface, much of the plasma's energy radiates into space; the cooler, denser plasma then sinks, driving further convection and creating circulating loops called convection cells
On very small scales this is basic molecular convection, but as we get into scales of tens and hundreds of feet, these convection cells
aggregate into thermals.
The entire surface is riddled with granulation: small convection cells
of hot gas rising from below, breaking up, and sinking back down on a timescale of just a few minutes.
In the near-surface region, small-scale convection cells
- about the size of California - generate sound waves that travel to the interior of the Sun and are refracted back to the surface.
Sloping roofs can result in convection cells
, and worse.
Oceanic islands tend to occur at the young ends of hotspot trails because they record the passage of oceanic plates over rising convection cells
(plumes) in the mantle, of the propagation of cracks in the lithosphere.
The rigid outer layer of our planet, called the lithosphere, is the cold, top boundary of convection cells
in the mantle.
Using a suitable catalyzing agent such as temperature differential, fluid in a pan evolves into a more complex structure, convection cells
, which are considered an emergent property.
