... On the base of laboratory simulations (on rotating shallow water) of the formation of spiral arms in galactic gaseous disks, the existence of giant anticyclones in them was predicted. Numerical simulations shown that the vortex structures arise on a linear stage of spiral arms formation simultaneously with the latter. ... Thus second giants structures, after spiral arms, in spiral galactic disks are discovered. ...
