Short summary
Spiral streaks or spirals are a common feature on satellite images of the sea surface. Spirals are overwhelmingly cyclonic: they wind anticlockwise in the Northern Hemisphere. Based on a regional circulation model with very high resolution we concluded that submesoscale cyclonic eddies differ from anticyclonic eddies in three ways favoring the formation of spirals: they can be characterized by (a) higher angular velocity, (b) more pronounced differential rotation and (c) negative helicity.
