At cA = 150 nM, 29% of the vesicles display a vortex and the probability to observe vortices is further increased at cA = 300 nM. Both a single vortex (Fig. 2b) and double vortices (Fig. 2c) can be observed on a vesicle. To elucidate the formation and polarity of vortices, we ...
and also, there’s a delay," Judah Cohen, Ph.D. and an atmospheric and environmental scientist who studies the polar vortex, told FOX Weather. "So, you’ve been talking about a sudden stratospheric warming. It takes about two weeks for the effects of the sudden stratospheric...

Obtaining high-rate data from the mesosphere-lower thermosphere region is a chal- lenge, and continuous ground observations of the mesospheric wind and temperature in the vicinity of the stratospheric polar vortex edge are still rare. Furthermore, sudden strato- spheric warming (SSW) manifestations...

The in-plane displacement direction maps clearly reveal that unidirectional polar order dominates in the top half of the particle while a counterclockwise vortex exists in the bottom half. This corresponds to the theoretically predicted polar-toroidal multiorder (PTMO) state, in which the polar and ...
