about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale)...

directionality or polar pattern indicates how sensitive it is to sounds arriving at different angles about its central axis. The polar patterns illustrated...

space. Venus Express observed two large shape-shifting vortices on Venus' poles (polar vortices) in 2006 on one of its close-up flybys of the planet. The...
