Tuesday, August 9, 2011 – Cloud haze spreads out with overlapping wave grid patterns. An expanded chemtrail cloud with a straight edge becomes filled with waves around a center hole. In just a few minutes time, the waves form spiral arms that resemble a hurricane on satellite radar. Another chemtrail line segment is captured forming HAARP waves and twisting around a vortex hole.
Pictures of persistent contrails used on Wikipedia to describe the word, “vortex”:
A vortex (plural: vortices) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex
