Goldreich–Sridhar theory models a form of this phenomenon caused by shear Alfvén waves. Solenoidal and compressive forcings due to this phenomenon respectively (-5[1])decrease and increase star formation rate in molecular clouds. In accretion disks, magnetic fields act as springs in a mechanism leading (-5[1])to the onset of this phenomenon, which causes increased angular momentum transport. (-5[1])Deformable mirrors are used to correct for wavefront distortions caused by this phenomenon (-5[2])in the atmosphere in adaptive optics. The electrothermal (-5[1])and magnetorotational instabilities lead to this phenomenon (-5[1])in astrophysical plasmas. High wind shear (10[1])causes a “clear-air” form of this phenomenon (-5[1])in the jet stream (10[2])that can cause structural damage to airplanes. (10[2])For 10 points, give this phenomenon of chaotic fluid (10[1])flow. (10[1])■END■ (10[15])
