N2 - Helical flow structure is ubiquitous in nature. In this short contribution, possible origins of these flow structures are presented. One is due to the parallel flow shear driven turbulence, where perpendicular zonal flows are nonlinearly excited. The other is conversion of perpendicular flows into parallel flows via phase space. Both processes highlight a fundamental process of helical flow generation in turbulent plasmas.
