The dawnside auroral polarization stream is a unique type of plasma wind in Earth′s high-latitude ionosphere. These streams play a key role in shaping the aurora and affecting how energy enters from space into the atmosphere. In this study, we explore when and where these streams are most likely to occur. The results not only help us better understand what causes them but also increase the ability to predict space weather events related to them, such as variations in atmosphere temperature.
