... The CME was formed at a distance of 0.2 0.5 R from the Sun's surface as a U-shaped structure, which was observed both in the 171 њ A images and in white-light. ... When the CME passes from TESIS Fe 171 њ to A LASCO C2 field of view, we see complete correspondence between the bright structures on the TESIS and LASCO images (see Figure 4b,c). Since bright structures on LASCO images are density structure, then the CME on TESIS Fe 171 њ images is also a density structure. ... Figure 2. ...

... In this case, the main vortex in the Benard cell is decomposed into smaller ones as a result of ten perioddoubling bifurcations. It is shown that the resulting turbulence is coherent and determinate; the fractal character (local selfsimilarity) of its spectrum is found. ... It is shown that the real atmospheric turbulence is the result of mixing of different coherent structures. ...
